This page describe bug fixes and other user-visible changes in each version released (starting at version 1.0.0.0). To check the version of mtvp, type:

$ mtvp -h | head

or use the menu Help->About... with mtv.

• Improved the Video Output Handler (VOH) architecture.

• Fixed bug: Name of video window and icon was not set properly, causing problems with some window managers.

• Fixed bug: Fixed deadlock problem when running with Linux kernel 2.2.x: mtv freezes when switching to root window of full-screen while playing.

• Fixed bug: Fixed yet another synchronization problem causing video to be jerky.

• Fixed bug: Fixed race-condition in the display thread that was causing occasional lock-ups on fast or multi-processors systems.

• Fixed bug: Fixed synchronization problem that was causing poor A/V sync on slow machines using display thread.

• Fixed bug: Fixed flickering problem in Full-screen.

• Fixed bug: Now video playback is much smoother, and a slightly more accurate IDCT is used (better image quality).

• Fixed bug: Fixed several bugs in display thread syncronization that was causing player to lock-up occasionally at startup.

• This version has a serious bug that may cause the player to lock-up at startup when the display thread is used (linux-glibc, Solaris). Please upgrade if you have this problem.

• This version has a serious bug that may cause the player to lock-up at startup when the display thread is used (linux-glibc, Solaris). Please upgrade if you have this problem.

• New: added support for Netscape remote control in mtv.

• Changed: Changed Splash screen and Help menu, added direct access to registration page, force to read License if not registered.

• New: mtv and mtvp-sdk are now available for Digital-Unix 4.0 for Alpha.

• Bug workaround: Some versions of the OSS audio driver for Linux (PPC, Alpha) have bugs and/or unimplemented ioctl that were causing problems with mtvp. The mtvp audio library has been improved and now works better in those conditions.

• Changed: Meaning of env variable MTVP_AUDIO_OSS_DELAY_METHOD has slightly changed. Type "mtvp -h" to see the details.

• New: mtvp-sdk is now available for Linux-ppc.

• Fixed bug: Fixed a problem in display thread syncronization that was causing player to lock-up occasionally at startup. The problem was seen only on multiprocessor Solaris-SPARC systems.

• Fixed bug: It was not possible to kill mtvp with ^C or the TERM signal.

• Fixed bug: Old/expired versions of mtv will still work, but with a warning.

• Fixed bug: Fixed a bug that was triggered on linux-alpha (uninitialized variable was causing arithmetic exception).

• New feature: Added new full-screen mode (Linux).

• Fixed bug: Video is now displayed properly in 24-bit depth on Matrox Millenium boards. Problem was traced to a typo.

• Fixed bug: Fixed XIL-related bug on Solaris: clicking on the Zoom button after resizing the window could produce an incorrect display.

• Fixed bug: Got rid of spurious "operation non implemented" message when starting mtv with -p option. Frame info would sometimes not be updated to represent currently displayed frame. This has been fixed.

• Performances: Better 64-bit motion compensation code. Now slightly faster on alpha systems.

• Fixed bug: Corrected an alignment problem on alpha. As a result the player is now significantly faster on alpha systems.

• Fixed bug: When using the display thread, video was sometimes playing too fast and not in sync with audio.

• Fixed bug: When using the display thread, resizing or zooming the video window was causing the player to freeze or crash.

• Fixed bug: When using the display thread, resizing or zooming the video window when player was paused or stopped would not redisplay the current frame properly.

• The display thread is now enabled on Solaris 2.5.

• The display operations (including chroma conversion, scaling and display itself) are now handled by a separate thread, whenever possible.

  Currently the display thread is used on Solaris-SPARC (requires Solaris 2.6 or later and the XIL libraries) and Linux glibc systems.

  Using a display thread generally improves the performances and takes better advantage of multiprocessors hardware. For example, on a dual-processor SS20 with 40MHz CPUs, frame rate goes up to 15 fps with 100% use of both CPUs, to compare to 10 fps without the display thread.

  In some cases, using the display thread may cause problems with the X library. If this happens, you should disable the display thread by setting the env variable MTVP_DISPLAY_THREAD_MODE to the appropriate value.

• New feature: On systems where the display thread is available, the user can select the display thread mode using the env variable MTVP_DISPLAY_THREAD_MODE:
  • 0 = Use display thread when using shared memory (default)
  • 1 = Always use display thread
  • 2 = Never use display thread

• Added support for streming from HTTP and FTP.

• New feature: Now input stream can be identified by URL. URL must be the location of an MPEG-1 Video or Systems stream. URL may be:
  • file:<filename> or just <filename>
  • fd:<filedescriptor> (e.g. fd:0 for stdin), or '-' for stdin
  • http://<hostname>/{<dir>/}<filename>
  • ftp://<hostname>/{<dir>/}<filename>
  • udp:<port-number> (e.g. udp:8888)
  • vcd:<track-number> (e.g. vcd:1)

• Removed options -U and -P, which are not necessary anymore.

• New SIH plugin API replaces old SII plugin API.

• Fixed bug: Fixed a problem that was causing the player to sometimes "lockup" at startup, particularly on Linux systems. The problem was traced to what seems to be a bug of 'select'.

• Change: Reduced memory usage by 2 Meg when using 24-bit or 32-bit depth display. The new 24-bit YUV to RGB conversion appears to be slightly slower on some systems, but the gain in quality and in memory usage seems to be worth it.

• Fixed bug: Fixed problem with VCD playback that was introduced in 1.0.6.5.

• Fixed bug: Correct error handling is done in mtv when trying to play a VCD while the CD in the drive has no XA track.

• Fixed bug: Under Solaris, player would die at startup if /dev/audioctl could not be opened (e.g. bad permissions).

• Change: Add reminder window in mtv. Each time an unregistered player leaves the PLAYING state, a windows reminds the user to register the shareware.

• Fixed bug: Worked around a bug in the Solaris 2.5 pthread library that was causing option -w (trace) to core dump.

• Fixed bug: In 8-bit color mode (dithered), zooming was not always working, depending on the window manager and/or X server. It looks like our attempt to unmap the window while updating the colormap was causing ConfigureNotify events with somehow the old window size in the even, which was causing the problem.

• Change: Internal code is now fully re-entrant and multithreaded.

• Fixed bug: In the threaded versions (i.e. Linux and Solaris), seeking while playing a video elementary stream could cause the player to freeze or die. This problem has been fixed.

• Change: When playing VCD, player now automatically plays next track when the end of current track is reached. This new behaviour was suggested by several users.

• Change: Audio decoder is now running in a thread (rather than a process) on platforms that support pthread (Solaris, Linux).

• Fixed bug: _fini() is now called if a COM_QUIT command is sent to a Player that is linked to an SII plugin.

• Fixed bug: Fixed a race condition in mtvp that was causing the audio process to die at startup and mtvp to bail out immediately (unless started with -a0 i.e. no audio). This problem is now fixed.

• Fixed bug: Audio quality and channel (left/right/stereo) was sometimes reset to medium quality left channel when seeking or opening a new stream. This bug, that was introduced in recent releases, is now fixed.

• Fixed bug: Under Linux, when playing in the root window with a PseudoColor visual, setting a private colormap then quitting mtvp was causing the root window to be left with no colormap. Any window subsequently created by the window manager had no decoration. Although I believe that it is somehow a bug of the window manager, the problem has been fixed and mtvp reattachs the original colormap to the root window before exiting.

• Fixed bug: When playing in an existing window, mtvp was always using a private colormap, even if the colormap was associated with the window and had enough colors. This is fixed.

• New port: Linux for PowerPC (should also support MkLinux).

• New feature: Added 'Play from UDP Socket' in mtv's file menu. Playing from a UDP socket is implemented only in multithreaded versions of mtvp (i.e. Linux and Solaris).

• Fixed bug: Fixed problem in audio delay handling that was causing audio/video sync to be slightly off in some cases.

• Fixed bug: If Fast-forward was used, opening a new stream coded with a different nominal framerate was causing mtvp to play the new stream at the nominal framerate of the first stream, and audio was not played (because audio can only be played at nominal framerate). This is fixed.

• Fixed bug: Sometimes audio PTS were not matched properly, causing audio to be out of sync or video to be jittery. This is fixed.

• Fixed bug: Changing the contrast and brightness when playing a VCD was causing the player to crash. This is fixed.

• Fixed bug: Using the "Save As" command while playing a VCD was causing the player to chash. This is fixed: it is now possible to save VCD tracks.

• Fixed bug: Player would die after about 3 min when playing the easter-egg (rolling dice gimmick).

• Change: The Linux version of the Player is now dynamically linked with libpthread-mpegtv.so.0.7.

• Fixed bug: BSD/OS version of mtv now recognizes the key read from the ~/.mtvrc file.

• Fixed bug: BSD/OS version was very hanging frequently. The problem was traced to a spurious signal 2 (SIGINT) being sent to the mtvp process. The occurence of this signal was found to be related to a negative sleep time value occasionally passed to usleep() when the end of a stream was reached. This is now fixed.

• Fixed bug: A problem in the handling of audio PTS could in some cases cause the Player to loose audio sync or to get degraded performances. This problem has been fixed.

• Fixed bug: Player now works properly in push mode, i.e. Player can read from a source that delivers the coded stream at its nominal bitrate. In case an underflow occurs, Player pauses then restart when enough data has been prefetched.

• New feature: Linux version can now play VCDs directly (without xreadvcd), provided of course that your kernel supports the CDROMREADRAW ioctl which is necessary to read VCDs.
  • To play a VCD, put the VCD in your drive and select "Play VCD" in the File menu. Change tracks with the track selector in the bottom-left corner of the control pannel.

  • To eject the VCD you must first close the file ("Close" in the File menu).

  The default CD-ROM device name is /dev/cdrom. If you use another device name, set the env variable MTV_VCD_DEVICE (e.g. "$ setenv MTV_VCD_DEVICE /dev/cdrom0").

  Information regarding kernel versions and kernel patches that you may need are available in ftp://ftp.mpegtv.com/pub/mpeg/mpegtv/xreadvcd/README-xreadvcd. The kernel patches are included in the xreadvcd source package available from this ftp directory.

• Performances: The Stream Input Interface in the Linux and Solaris versions are now fully multithreaded. This improves significantly the performances when playing from a network or slow devices (e.g. CD-ROM).

• Fixed bug: Fixed a problem that was causing mtvp to never display the last frame of a sequence in some cases.

• New feature: Added chroma saturation control.

• Fixed bug: Fixed a problem that was causing ennoying vertical strip artifacts in the image in some cases.

• Fixed bug: Fixed mtvp's option -z.

• New feature: Enforce audio limit for unregistered players.

• Fixed bug: Player could sometimes render the X server sluggish to the point it was unusable (mouse pointer would not move). This problem has been fixed.

• Fixed bug: Player could crash if an attempt was made to open a non-MPEG file while playing another stream.

• Fixed bug: Player would sometimes get stuck when user presses paused then play rapidely while playing.

• New feature: Added expiration date to unregistered copies of mtv.

• New feature: Added menu Window->Play-in-root-window to display the video in the root window.

• New feature: Player uses higher quality 8-bit dithering when paused or stop.

• Fixed bug: Fixed several problems related to changes in the color mode.

• Fixed bug: Fixed a problem in fast 8-bit 2x2 zoom dithering.

• Fixed bug: When using XIL and an existing window, image is now centered.

• Fixed bug: Fixed bug that was causing plugin image to be move to the top-left corner of the navigator's window.

• New feature: Added pel-aspect-ratio control (XIL-accelerated version only).

• Fixed bug: Fixed problem with Matrox Millenium in 24-bit mode.

• Fixed bug: In "Gray" color mode, when horizontal_size or vertical_size was not multiple of 16, 2X2 zoom was broken.

• Change: Added splash screen to remind people that they should register if they use the Player. Added Registration key management in mtv.

• Change: Changed the terms of the Shareware license.

• Fixed bug: Fixed a bug that was introduced in 1.0.3.4 with all the major scaling changes done to support XIL: when horizontal_size or vertical_size was not multiple of 16, 2X2 zoom was broken.

• Change: Now mtv and xreadvcd uses Xforms-0.88.

• Change: xreadvcd-0.4 now bundled with Linux version.

• Fixed bug: Fixed a problem with Accelerated-X 3.1 and 4.1 in overlay mode with TrueColor visual.

• Fixed bug: A typo in the code was causing the player to not use of X shared memory in some cases without notifying user of the problem. This is fixed.

• Fixed bug: A race condition in mtv could cause the player's state to become "Stopped" after seeking, causing play to rewind.

• Fixed bug: When it was not possible to establish a connection to an X server (e.g. DISPLAY not properly defined), player would die or core dump with no message.

• Performances: Improved resilience to streams with incorrect or non-sequencial PTS/DTS. The player now works well to play Video CDs with xreadvcd.

• Video CD support: (Linux) A patched version of Ales Makarov's xreadvcd-0.3 is included. The patches resolves a number of problems with the original xreadvcd-0.3 (including performance problems). To play a Video CD, just get the xreadvcd binary (xreadvcd.gz), pop the Video CD in the drive and type "xreadvcd | mtv -". If it does not work, you should get the xreadvcd-0.3-patched distribution and read the README file. You may need to install some system patches to read Video CDs on your system.

• Fixed bug: Fixed a problem that was causing problems with the plug-in.

• Fixed bug: mtv's option -a2, that got broken in version 1.0.3.2, works again.

• New feature: mtvp now recognizes the env variable MTVP_FRAMERATE can be used to set a default framerate. See "mtvp -h" for details.

• Fixed bug: Closing a stream while playing would sometimes cause mtvp to die.

• New feature: XIL-accelerated version for Solaris SPARC.

  With the XIL-accelerated version the video window can be resized to any size (up to full screen). Requires the XIL library (libxil.so.1), an optionnal package only available with Solaris 2.5 and later. XIL is part of the package SUNWits (at least with Solaris 2.5.1). If you have Solaris 2.5 or 2.6, you should be able to install the XIL library from the Solaris system CDROM. Because XIL is not available on all Solaris systems, a non-XIL version will still be provided. The non-XIL version will only support 1X1 and 2x2 zooming. For more information on the XIL-accelerated version read the README-XIL file.

• New feature: It is now possible to zoom by resizing (or maximizing) the window. The Zoom button still works, of course. The initial video size when a new file is opened is determined by the Zoom button. This feature is disabled on HP (problems because of a bug in HP's X server).

• Performances: Smoother playback, specially on fast machines.

• Fixed bug: mtv's option -sf to specify a framerate now works.

• Fixed bug: Until now, when playing a systems stream, Player was attempting to decode only video stream #0 and audio stream #0. Now player selects the first video and audio streams encountered, which allows decoding of streams where audio and video streams #1 are used. Ideally it should be possible to tell which video and audio streams should be selected, and in case the player does the selection automatically, it should be possible to ask the player which streams have been selected but those features are not (yet) implemented.

• New feature: Added easter egg.

• Performances: Slightly improved.

• Fixed bug: Fixed a problem in the systems parser that was causing garbage to be decoded occasionally.

• New feature: Added easter egg.

• Fixed bug: When mtvp was streaming from stdin and had no controling application, it was not handling X Expose events when data was not available on input. This was causing the plug-in to not refresh its display properly.

• Fixed bug: Under HP-UX, fixed several bugs related to audio ports selection.

• Performances: Under HP-UX, the performances are slightly improved.

• Availability: The player now works very well under FreeBSD using the Linux or BSD/OS emulation and recent audio drivers. For details, see the System Requirements for FreeBSD on the Download page.

• Fixed bug: On systems using the OSS audio driver (e.g. Linux), the audio device is now opened without O_NONBLOCK. Even though OSS currently ignores this flag, OSS-compatible drivers on FreeBSD did not ignore it, and that was creating problems.

• New feature: On systems using the OSS audio driver (e.g. Linux), the user can select the strategy used by the player to access the delay on which the a/v sync is based, using the env variable MTVP_AUDIO_OSS_DELAY_METHOD. Type "mtvp -h" for details.

• New feature: The user can select the strategy used by the player to read the input stream, using the env variable MTVP_SYS_READ_STRATEGY. Type "mtvp -h" for details.

• Fixed bug: Under HP-UX, fixed a bug that was causing audio to mute with "Invalid parameter" message when changing audio quality from ulaw to medium or high.

• Fixed bug: Under HP-UX, fixed a bug that was preventing 48 KHz audio to play in medium quality.

• Fixed bug: Worked around a bug in the OSS audio driver (e.g. with Linux) that causes sometimes I/O errors when seeking.

• Fixed bug: Fixed a race condition in mtv that was causing the player to stop when seeking while playing.

• Fixed bug: Under HP-UX, mtvp now works around a bug in the HP-UX audio driver to fixe the problem of audio muting with "Device busy" message.

• Fixed bug: Under HP-UX, mtvp now compensates for the non-linearity of audio levels.

• New feature: mtv now checks the Xforms library version and complains if it is not the versions expected.

• New feature: mtv now requires libforms.so.0.87.

• Fixed bug: On SCO and HP-UX, upon exiting, player would sometimes enter a recursive loop, allocating all the available memory before dying with an error message. This should be fixed now.

• MpegTV Player 1.0 now available for SCO OpenServer Release 5 (aka SCO_SV 3.2).

• Fixed bug: In some cases the selected audio ports were not indicated correctly.

• Change: Player does not change audio volume at startup. Note that on systems with an audio mixer (e.g. Linux), if the Master Volume (mixer) is set to 0, you will not hear any audio even if you set the PCM Volume to max using the Player's control.

• New feature: License is displayed when the program is run the first time.

• New feature: New Options menu command "Save Options" saves current settings in the file ~/.mtvrc. Currently the setting that can be saved are: Audio channel, Audio quality, Video gamma, contrast and brightness, Sync options, zoom, loop and auto-play.

• New feature: New mtv option -sf can be used to specify an arbitrary video framerate (default is nominal framerate).

• Fixed bug: On HP-UX, killing the player could cause mtv to enter a recursive loop, allocating all the available memory before dying with an error message. This problem is now fixed.

• Fixed bug: the elapsed time and total time were showing times only multiple of 8 seconds. This is now fixed.

• Fixed bug: In some cases, Xforms used to print some warning messages like:

  In MapColor [flcolor.c 791] ColormapFull. Using substitutions
Failed to share colors. Using Private Color Map

  This is now fixed (Xforms warning messages are not printed anymore).

• Fixed bug: Improved audio/video sync on Solaris x86 with Sun's sbpro audio driver. However, because of limitations in Sun's sbpro audio driver, audio/video sync cannot be perfect. A better synchronization can be achieved using the OSS/Solaris audio driver.

• Fixed bug: Under Solaris SPARC, Audio ports can now be selected before opening a stream.

• Fixed bug: Fragment size is now set to a correct value when using low quality audio, which correct sync problems in this mode.

• New feature: New environment variable MTVP_AUDIO_OSS_FRAG_SPEC can be used to control the fragment size when using the OSS driver. Smaller fragment size improve the timing accuracy of lip-sync at a performance cost.

• Fixed bug: Elapsed play-time (on left side of slide-bar) is now available even when stream is not seek-able (e.g. when streaming from a pipe).
• New Feature: You can hide/show the Controls by clicking on the Video window.
• New Feature: New choice in the "Framerate & Sync" Options: "Play at nominal framerate" which is the default.
• Fixed bug: Now, when the user selects "Play at specified framerate", the specified framerate is not reset (as it used to be) when opening a new stream.
• Fixed bug: When a Window-ID is specified (with option -W), video is now properly centered in the specified window (used to be displayed at the top-left corner of the specified window).
• Fixed bug: Lip-sync should be better in some cases (to be checked).
• Fixed bug: Improved streaming support. Player works better in streaming situations where the source annot always deliver at the nominal bitrate.

• Fixed bug: A bug was introduced in previous versions that was causing the player to display with a lower framerate than expected, specially on fast systems. Typically, if the CPU power was just enough to play video at the full framerate, the Player was playing at a much slower framerate and was not using 100% of the available CPU. This is now fixed.

• New feature: MpegTV Player 1.0 is not "limited" to 30 second anymore. Player is free for non-commercial use. A new licensing scheme now applies. Please read the new LICENSE file for details. Note: License keys purchased for earlier versions continue to give access to the run-time Player's API.
• Changed API version: Version changed to 4 due to (minor) semantic changes in some commands.
• Changed API: COM_SEEK and COM_END do not change the Player state. In earlier versions, those commands used to change the state to "paused".
• New feature: In mtv, the commands |< (go to beginning) and >| (go to end) now do not change the state of the player, i.e. if player was playing, it continues to play after executing the commands. In earlier versions, those commands used to change the state to "paused".
• Changed: In mtv, the cosmetic aspect of the "Sync" dialog has been improved.
• Changed: In mtv and mtvp, option -n has been removed.
• Fixed (major) bug: Player now takes commands even when stream input is blocked (e.g. no data available on pipe or socket). A small cosmetic bug remains: display is not repainted if the window is obscured while stream input is blocked. In previous versions, player would not take any command when blocked on input.
• New feature: In mtv, new menu item File->Play-from-Stdin. Note: this command works only if Stdin is a pipe, file or socket, not a terminal. Data needs to be available for reading on stdin in order for that to work.
• Fixed bug: In mtv, options -amv-1 and -amb-1 now work, i.e. they keep the current master audio volume/balance settings.
• New feature: In mtv, new menu item Help->License displays the License.
• Fixed bug: Fixed framerate sync. In some cases, like playing at a very slow framerate (e.g. 1 frame/sec), framerate was quite erratic. Now plays at a regular rate, even slow.

• Fixed bug: In front-end mtv, got rid of spurious warning (Warning: Audio disabled) when un-Muting the player.
• Change default: When using an OSS audio driver: Now the default for the volume and balance controls is to be tied to the PCM control, not to the master (mixer) control. Unless otherwise specified with option -amv-1 and -amb-1, the master volume and balance are set to some acceptable values at start-up.
• Fixed bug: When the audio driver not OSS, the player does not set the initial volume and balance values at start-up, unless options -apv or -apb are used. Previous versions had a bug caused by the fact that option -amv was considered to be equivalent to -apv when there was no mixer.
• New feature: When master (mixer) controls are not available, the front-end received a message of type S2A_COM_NO_CONTROLS_SELECT that can be used to disable the master audio control selection.
• Fixed bug: Fixed a bug that was introduced in 1.0.1.8 and could cause the player to abort when closing the audio device.

• New feature: Solaris-sparc and Solaris-x86 versions now support both the OSS audio driver API (/dev/dsp) and the Sun audio driver API (/dev/audio).

  If the device /dev/dsp is found, it is assumed that the OSS API should be used, unless otherwise specified (see environment variable MTVP_AUDIO_API).

  Note that the Solaris-x86 audio driver has a bug that prevents correct audio/video sync. The OSS/Solaris driver v3.8d (dated 3pm July 7 1997 or later) works well. Previous versions of OSS/Solaris are broken.

• New feature: The player (mtvp) now recognizes the following environment variables:
  • MTVP_AUDIO_API = audio driver API
    0 = Sun API, 1 = OSS API
    Default: OSS API if /dev/dsp is found, Sun API otherwise.
  • MTVP_AUDIO_DEVICE_MAIN = name of main audio device
    Default: /dev/audio if Sun API, /dev/dsp if OSS API.
  • MTVP_AUDIO_DEVICE_CONTROL = name of control audio device
    Default: /dev/audioctl if Sun API, /dev/mixer if OSS API.
  • MTVP_AUDIO_DEVICE_ULAW = name of ulaw audio device (default /dev/audio).

  MTVP_AUDIO_API is available only on systems supporting several different audio drivers (e.g. Solaris). It is ignored on systems that support only the OSS API (e.g Linux).

  All those environment variables are ignored on Irix systems, because the SGI audio API does not use /dev/... device descriptors.

• New feature: The Irix version of the player (mtvp) now recognizes the following environment variable:
  • MTVP_AUDIO_SGI_DELAY_METHOD = method used to compute audio delay
    0 = simple method using ALgetfilled() (default)
    1 = more complicated method using dmGetUST(), ALgetframetime() and ALgetframetime()
    
  The default method seems to work well on most systems. The complicated method may work better on fast systems (it is more accurate, in theory). Please tell us if you see any difference.

• Performance: Irix version is about 5% faster than previous release. Now about 20% faster than SGI's movieplayer on my Indy.

• Bug fixed: In Irix version, changed the Xforms options in mtv to prevent the famous "clipped-menus" bug. Now the options passed by mtv to fl_initialize() are: -visual Default -depth 8. You can change them by recompiling mtv if needed, or overwrite them with mtv option '+' (see mtv -h).

• Performance: Slightly better performances and lower memory usage. Improved Video/Audio sync.
• New feature: In mtv, added warning when the user un-mutes the player while not in Sync mode.

• Performance: The Solaris-x86 version is now about 25% faster on Pentium (compared to version 1.0.1.3). This gain was achieved by compiling mtvp with a Pentium-optimized compiler.
• Added to API: The API package now contains the object libraries for the Solaris-x86 version.

• Bug fixed: Audio/Video sync has been significantly improved on slow systems.
• New feature: The default gamma correction values are now platform dependent. New default values are chosen to match better the type of monitor generally used with each platform.

• Added to API: COM_SEND_GOP_INFOS (int). Parameter must be 0 or 1. This command is used to tell the player whether or not to send A2G_COM_GOP_INFOS messages for each gop decoded while playing.
• Added to API: A2G_COM_GOP_INFOS. Parameter is a structure of type PMP_DATA_GOP_INFOS. This message is sent by the player each time a GOP header is decoded. The message parameter contains all the info found in the GOP header (including the time-code). By default A2G_COM_GOP_INFOS messages are not sent while playing, to avoid unnecessary overhead. This can be changed using COM_SEND_GOP_INFOS.

• New feature: The mtv front-end now requires libforms.so.0.86. The source code of mtv remains compatible with both libforms.so.0.81 and libforms.so.0.86.
• New feature: Socket/pipe support has been improved. In particular, the Player continues playing video even if input is not available from the pipe or socket for short periods of time (e.g. one second). Previous versions of the Player would cause the video to freeze in this case.
• Added to API: COM_VIDEO_FREEZE (int). Parameter must be 0 or 1. COM_VIDEO_FREEZE (1) disabled any display update. COM_VIDEO_FREEZE (0) enables display update (default).
• Bug fixed: Fixed a problem when changing audio quality of streams with audio sampling frequency not supported by the audio driver.

• New feature: Added support for #-comments in mtvp.key file.

• Bug fixed: Added support for env variable MTVP_GET_WINDOW_ORIGIN_METHOD to fix zoom window position problem under xview_3.2p1.3.orig.tar.gz (olwm/olvwm) under Linux.

• Bug fixed: Layer 2 joint stereo audio was not decoded properly.
• Bug fixed: The Linux-specific optimization for audio was accidentally turned off.

• Bug fixed: Audio was bad on the right channel when encoded in Layer 2 joint stereo.
• Bug fixed: The "Unregistered software" warning was displayed when the player had been registered and the key had expired.

• Bug fixed: When player was stopped and FFW was used, the slide-bar was not updated.
• Bug fixed: When player was stopped, seeking did not change the state in the Control's window title to "Paused".
• Bug fixed: Muting the Player was causing problems with streams that have very low audio bitrate (32 Kbit/sec), like those found in http://208.196.157.36/smirror/fusionfilms/. In some cases, up to 20 sec of audio would not play after un-muting. This problem was caused by Player flushing audio packets when muting. Now the behavior of the Player when muting with this type of streams is much better.
• Bug fixed: On Linux, in some cases, after seeking in the last 2 seconds before the end of a stream and playing, audio would not play. This was cause by an incorrect method for triggering audio output: Audio output was triggered only when the audio driver's FIFO was getting full (which in this cases never happened). Now, audio output is also triggered when the input buffer gets empty, which resolves this problem.
• Bug fixed: On Solaris and Irix, Player could sometimes get out of sync when seeking in very low bitrate streams, because of a bug in the usleep() emulation using select().

• Bug fixed: Pausing the Player was causing problems with streams that have very low audio bitrate (32 Kbit/sec), like those found in http://208.196.157.36/smirror/fusionfilms/. In some cases, up to 20 sec of audio would not play after restarting the Player. This problem was caused by Player flushing audio packets when pausing. Now the behavior of the Player when pausing with this type of streams is much better, but a similar problem still exist with mute.
• Change in behavior: Seeking with the slide bar while playing does not cause the Player to go in the pause state, as it used to. Now, once the slide bar is released, the Player returns to playing mode, which is more convenient.
• Change in API: In order to permit the change above, the API behavior had to be slightly modified. Now the A2G_COM_STATE message is received only when the state of the Player changes spontaneously (e.g. the player stops when the end of a file is reached). It is not received when the state changes because a command that causes (or may cause) the state to change was issued. Commands that may change the state are COM_STATE, COM_SEEK, COM_END, COM_CLOSE etc.
• Added to API: A2G_COM_SYSTEMS_END_CODE, sent when a systems-end-code is found.
• Added to API: A2G_COM_VIDEO_END_CODE, sent when a video-end-code is found.

• Bug fixed: Player's window was not resized properly when playing concatenated sequences with different picture size.
• Bug fixed: Player's window was not resized properly when zooming. This problem was accidentally introduced in version 1.0.0.6.

• This version should not be used, because of some serious bugs.

• New feature: mtv option -F[=][<width>{xX}<height>][{+-}<xoffset>{+-}<yoffset>] can be used to set the initial size and position of the control window.
• New feature: mtv option -G[=][<width>{xX}<height>][{+-}<xoffset>{+-}<yoffset>] can be used to set the initial size and position of the Player window. Currently width and height are ignored.

• Bug fixed: Player did not work if maximum depth of TrueColor visual was not a multiple of 8. This was a problem on some SGI systems.
• New feature: env variable MTVP_FULL_COLOR_MAX_DEPTH can be used to limit the depth. By default the Player creates a window with the maximum depth possible in TrueColor visual, up to 32.
• New feature: mtv option -i starts iconic Player controls.
• Change: mtv with no parameter does not open a file browser at startup anymore. To emulate the previous behavior of mtv, just give mtv a directory as parameter (e.g. "mtv .").
• Change: mtv option menu is now active even when no stream is opened.

• Bug fixed: Player's window and icon names were not set properly when video mode was changed.
• Added to API: commands to specify initial position of Player's window.

• Bug fixed: mtv's controls window title used to say "Playing" at startup when no stream was opened.
• mtv was modified to work around an Xform bug that was causing garbled text in alert windows in case of multiple alerts.
• Audio code was optimized, resulting is slight overall performance improvement.

• Bug fixed: a typo in the code was preventing efficient error concealment.
• Bug fixed: sometimes bad images were displayed when using option -S of mtv.
• Player was exiting with an internal error when given an MPEG-2 stream. Now the proper warning is displayed when attempting to play an MPEG-2 stream.
