[Ffmpeg-devel] Broken rv20 sample

[Roberto Togni]

Hi all

RV20 video from this stream
rtsp://ert.media.noc.ntua.gr:5554/encoder/tv.rm can't be played by
ffmpeg decoder (latest svn). A sample clip (dumped with MPlayer) can be
found at http://samples.mplayerhq.hu/real/VC-RV20/rv20errors.rm

The file works ok with the binary codec.

Some of the error messages are
