[opensuse] ffmpeg question
I have a brand new PSP, and I want to put some videos on it but it only supports. MP4 video files, I know that ffmpeg supports outputing to a psp compatable MP4 file because I have seen all of the GUI frontends for it, but I can't get them to work, so I figured I would give attempting this in the command line and I was wondering what the options that I would have to give to ffmpeg in order for it to do this. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

ffmpeg -i $name.flv -ar 22050 -ac 2 -acodec libfaac -vcodec h263 -s 352x288 -r 20 -b 5000 -ab 32 $name.mp4 The -acodec and -vcodec can directly use the library for audio and video codec, maybe you need change these for different converting. -- Sincerely Yours, Charles Li -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Is 352x288 the most the PSP supports? I have tried it on a short video that I have and it works but the video is originally 720x480 and when viewing the newly created mp4 video it looks squeezed to me. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

704x576 also should be work, but I'm not sure which one is the most PSP supports, I just used 352x288 in my mp4 player before. -- Sincerely Yours, Charles Li -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

ffmpeg -i $name.flv -ar 22050 -ac 2 -acodec libfaac -vcodec h263 -s 352x288 -r 20 -b 5000 -ab 32 $name.mp4 ^^^^ ^^ That's going to result in very bad quality video. FFmpeg takes those in bits per second, unlike mencoder which would assume you meant Kbps.

The FFmpeg FAQ[0] gives a bit of couple of example command lines: ffmpeg -i input \ -acodec libfaac -ab 128kb \ -vcodec mpeg4 -b 1200kb \ -ar 24000 -mbd 2 -flags +4mv+trell \ -aic 2 -cmp 2 -subcmp 2 -s 368x192 \ -r 30000/1001 -title X \ -f psp output.mp4 ffmpeg -i input \ -acodec libfaac -ab 128kb \ -vcodec h264 -b 1200kb \ -ar 48000 -mbd 2 \ -coder 1 -cmp 2 -subcmp 2 \ -s 368x192 -r 30000/1001 \ -title X -f psp \ -flags loop -trellis 2 \ -partitions parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 \ output.mp4 As to which one will give the better quality, I have no idea.
