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. also try +"VIDS:NSVI"
  4. after locating vidc.nsvi=nsvideo.dll try to locate nsvideo.dll
  5. search for "nsvideo.dl_" which may appear in the installer/zip logs
  6. also try .drv, .dr_, .exe, .zip, .sys, .ax etc.
  7. sometimes get lucky searching for "NSVI.rar" or "nsvi.zip" etc.
  8. try also the backward hex version of NSVI (4956534E) which is part of the GUID for the dshow codec.

unknown 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).

HHE1 - zvue video? hhe0 / hhe1 patent : http://www.freepatentsonline.com/y2007/0019741.html . looks like modified mpeg4.
.
official website in archive hheld.com zvue.com
zflicks 1.5 encodes to xvid, included with ZOrgInstall-1.0.1.exe
all of the -zvue.avi files are created with zflicks 1.1 , but zflicks 1.1 does not include the hhe0 or hhe1 codec. only divx.dll (comes with 1.1) or xvid (comes with 1.5).


speg - http://qstream.org/ appears to be an Xvid derivative- if you check out the source code, there's a patch mplayer-speg.patch
which just tacks SPEG onto all the xvid stuff. Dashcloud 14:23, 20 February 2009 (EST)

need to locate dlls

 gisz , gigasize.dll

actually, this file , when mplayer -dumpvideo gisz.avi seems to be only 230K of 'c:\gigasize\movie2_00000.gdv' repeating over and over again. so it looks like gisz fourcc is just a placeholder and not an actual codec. --Compn 09:25, 11 July 2012 (EDT)
