[MPlayer-advusers] ID_DEMUXER=nuv + ID_VIDEO_FORMAT=RJPG --> no picture ?!

[tormen at gmx.net]

Hi.

I have a .nuv file recorded with mythtv 0.20.1_p13344 which contains pcm 
uncompressed audio and RJPEG compressed video.
mythfrontend can play the video.

mplayer does not. It seems to detect the video-codec, but no picture 
appears.

Below you'll find info 
    1.) about the kernel,
    2.) about my mplayer version,
    3.) about what mplayer thinks of a sample video
    4.) about the sample video from nuvinfo (part of media-tv/nuvexport 0.4_p20061203)

The sample video is downloadable from: http://posern.org/test/sample.nuv

Is this a bug or a feature?

Thnx for any feedback in advance.

Greetings,

tormen.
