I'm trying to get flv videos to work on a coby mp815 digital media player. I have one file the coby can show $ mplayer -identify -frames 0 good.flv 2>&1 | grep -i codec Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family libavcodec version 53.54.100 (internal) Selected video codec: [ffflv] vfm: ffmpeg (FFmpeg Flash video) ID_VIDEO_CODEC=ffflv Requested audio codec family [mpg123] (afm=mpg123) not available. Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders Selected audio codec: [ffmp3float] afm: ffmpeg (FFmpeg MPEG layer-3 audio) ID_AUDIO_CODEC=ffmp3float $ and another it can't (format error) $ mplayer -identify -frames 0 bad.flv 2>&1 | grep -i codec Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family libavcodec version 53.54.100 (internal) Selected video codec: [ffvp6f] vfm: ffmpeg (FFmpeg VP6 Flash) ID_VIDEO_CODEC=ffvp6f Requested audio codec family [mpg123] (afm=mpg123) not available.

Doesn't work with filters. frameno - special audio-only file for 3-pass encoding, see DOCS. raw - uncompressed video. Use fourcc option to set format explicitly. nuv - nuppel video lavc - libavcodec codecs - best quality! vfw - VfW DLLs, read DOCS/HTML/en/encoding-guide.html. qtvideo - QuickTime DLLs, currently only SVQ1/3 are supported. libdv - DV encoding with libdv v0.9.5 xvid - XviD encoding x264 - H.264 encoding $ What is the magic I need to invoke to go from ffvp6f to ffflv? Is this even the right track? This is on debian testing updated weekly, if that's important.
