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:
- start with older files
- google the filename to see if it was posted to the mplayer/ffmpeg mailing list
- do a search at http://bugzilla.mplayerhq.hu and http://roundup.mplayerhq.hu to see if it was posted there
- if no text file exists, try playback using mplayer and ffplay
- move file to samples.mphq and create/modify bugreport or delete
TODO:
- organize incoming into folders like "known issues-to be fixed"
- fix communication between developers-samples status
- explain what samples are to be kept and which to be deleted
- ask other projects (xine,vlc) if they want to take a look at such files before deletion

try to guess codecs by forcing them.
mplayer -vc +ffodivx file.avi or -vc +ffmjpeg (for files that may be mjpeg)
Finding Codecs:
- google for NSVI fourcc for hints as to the codec name
- search for "VIDC.NSVI". vidc is found in .inf files (registry installer) for vfw codecs.
- after locating vidc.nsvi=nsvideo.dll try to locate nsvideo.dll
- search for "nsvideo.dl_" which may appear in the installer/zip logs
- also try .drv, .dr_, .exe, .zip, .sys, .ax etc.
- try also the backward hex version of NSVI (4956534E) which is part of the GUID for the dshow codec.

DPSH - http://mxhaard.free.fr/sview.html; some sort of raw codec-http://mxhaard.free.fr/spca50x/Download/spcagui20060127.tar.gz has the spcaview program that creates them (it segfaulted when I tried the example in the documentation).
