[MPlayer-users] Can't specify some raw video formats.

[Andy Furniss]

I am trying to play a certain raw video file, but I can't get many of 
the advertised format strings to be recognised.

mplayer -rawvideo format=help
Available formats: 444p16le 444p16be 444p14le 444p14be 444p12le 444p12be

Yet if I try to use some of these they don't get accepted -

working -

mplayer -vo gl -demuxer rawvideo  -rawvideo 
fps=25:w=704:h=576:format=i420 cact-422.yuv

but the yuv is not i420 - it's some variant of 422p - if I try

bash-3.2$ mplayer -vo gl -demuxer rawvideo  -rawvideo 
fps=25:w=704:h=576:format=422p cact-422.yuv

Playing cact-422.yuv.
rawvideo file format detected.
rawvideo: img size not specified and unknown format!

I have also tried the fourcc from ffmpeg output when making the file 
with ffmpeg -i infile outfile.yuy

Stream #0:0: Video: rawvideo (Y42B / 0x42323459), yuv422p, 704x576 [SAR 
1:1 DAR 11:9], q=2-31, 200 kb/s, 90k tbn, 25 tbc

but with the same results.

Am I doing something wrong?

Playing the mpeg2 source file works OK and looks like this -
