yes, I know about the YUV stuff, but it seems nobody ever got the driver to output YUV in any other res than 320x240. So said Randall (fxtv author) ... so I am playing with fxtv and ffmpeg, and while mpeg1video works great. mpeg4, msmpeg4, mjpeg seems to stream/encode fine too, but then I can not play the stream with anything ! I tried mplayer for example, and all I get is this: MPlayer 0.50pre-1(C) 2000-2001 Arpad Gereoffy (see DOCS!) Reading /home/bruno/.mplayer/codecs.conf: can't open '/home/bruno/.mplayer/codecs.conf': No such file or directory Reading /usr/local/share/mplayer/codecs.conf: 18 audio & 39 video codecs font: can't open file: /home/bruno/.mplayer/font/font.desc font: can't open file: /usr/local/share/mplayer/font/font.desc Playing test.mps Detected MPEG-PS file format! MPEG: FATAL: EOF while searching for sequence header Exiting... (End of file) mplayer -vc help shows (among others) ffmjpeg 5 working FFmpeg MJPEG decoder [mjpeg] ffi263 5 working FFmpeg I263 decoder [h263i] ffh263 5 working FFmpeg H263+ decoder [h263] ffdivx 5 working FFmpeg DivX ;-) (MS MPEG-4 v3) [msmpeg4] ffodivx 5 working FFmpeg OpenDivX [mpeg4] ffmpeg12 5 working FFmpeg-1 [mpegvideo] so, anybody can play mpeg4 streams generated by ffmpeg ? problem is I do not know if the player has a problem or the encoder or most probably the parameters are wrong. But ffmpeg output during encoding does not show anything special. bruno On Fri, 19 Oct 2001, Daniel O'Connor wrote: > > On 18-Oct-2001 bruno schwander wrote: > > Fxtv is actually consuming twice as much cpu time as ffmpeg (probably > > because of the conversion to ppm, and because I do some inefficient > > things) > > If you could get fxtv to dump YUV frames you would find it would be much more > efficient.. > > The BT8x8 cards can generate such frames, and mpeg encoding starts off by > generating YUV from RGB (and it is a major CPU killer - witness how much CPU > the Xv extension saves you when playing a movie - the CPU no longer has to do > YUV -> RGB) > > And, uhh, no, I have no patches :) > > > I'll post a link when I get there.
