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. try searching 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. try also searching for "nsvideo.dl_" which may appear in the installer/zip logs
