Revision as of 12:23, 20 February 2009

The MPlayer IRC and bug report monkey.


Take the Sample Challenge!
Review one file from /incoming/ per week! (+delete/move/report bug)
Extra Credit- Write a new audio/video codec/format on the wiki.

Steps to review incoming:

  1. start with older files
  2. google the filename to see if it was posted to the mplayer/ffmpeg mailing list
  3. do a search at http://bugzilla.mplayerhq.hu and http://roundup.mplayerhq.hu to see if it was posted there
  4. if no text file exists, try playback using mplayer and ffplay
  5. move file to samples.mphq and create/modify bugreport or delete

TODO:

  1. organize incoming into folders like "known issues-to be fixed"
  2. fix communication between developers-samples status
  3. explain what samples are to be kept and which to be deleted
  4. ask other projects (xine,vlc) if they want to take a look at such files before deletion


Multimedia Archaelogy

try to guess codecs by forcing them.

mplayer -vc +ffodivx file.avi or -vc +ffmjpeg (for files that may be mjpeg)

Finding Codecs:

  1. google for NSVI fourcc for hints as to the codec name
  2. search for "VIDC.NSVI". vidc is found in .inf files (registry installer) for vfw codecs.
  3. after locating vidc.nsvi=nsvideo.dll try to locate nsvideo.dll
  4. search for "nsvideo.dl_" which may appear in the installer/zip logs
  5. also try .drv, .dr_, .exe, .zip, .sys, .ax etc.
  6. try also the backward hex version of NSVI (4956534E) which is part of the GUID for the dshow codec.
