problems with play

With decoders installed, ffdshow, and koepi's latest XviD codec, some avi xvid video files still play without video (audio ok, no video). Yet the same files will play successfully in vlan player.

[ISFT]	MEncoder 1.0pre6-3.2.3

[JUNK]	 MPlayer junk data

This seems to be an issue with XviD encoded on Linux with MEncoder.

Missing or Truncated Index

You may have downloaded an XviD avi that appears complete but is missing the tail end of the file. It may be that your download stalled at 99%. The offsets and sizes of the index can be recovered by scanning the entire file, however, the key frame flags that are required for seeking and decoding will not be recovered in this way. Seeking forward or back in the media player such as vlc may be slow or stall completely. mplayer, vlc, and windows media player may all have trouble seeking (skipping forward or back) from within such a broken video file.

Repair of the broken XviD without reencoding is possible with certain tools in most circumstances. DivXFix++ is a tool designed to repair broken AVI file streams by rebuilding index part of file, and works on Linux, Windows, and Mac. MPEG4 Modifier modifies a MPEG-4 ASP video (AVI with XviD, DivX) without re-encoding (change aspect ratio, edit userdata, remove or add packed bitstream, and change interlaced field order). Requires sucky .NET Framework 2.0.

Software

• MPlayer will render both video and sound for an xvid with this particular encoding glitch.

Troubleshooting

Ever notice an Xvid or Divx video that played just slightly too fast? "The speed difference is so slight that you really can't tell until you watch the original and hear that the theme song is in a lower key and the voices are lower." See Video Playback Slightly Too Fast.
