[Mplayer-advusers] codec tsccvid.dll: playback fails if vid.res. is 1024:768 (device is incompatible with this codec)

Sun Feb 15 16:18:20 CET 2004

Simply solution found:
The codecs.conf entry has to be updated from out "BGR15 flip" to out "BGR15,BGR16 flip"
please fix this in the official release of mplayer:

codecs.conf:

; sample videos: http://www.techsmith.com/products/camtasia/examplevideos.asp
videocodec camtasia
  info "TechSmith Camtasia Screen Codec"
  status working
  fourcc TSCC,tscc
  driver vfw
  dll "tsccvid.dll"
  out BGR15,BGR24 flip
