Hi,

I found in libavformat/movenc.h

there's

*#define MODE_PSP 0x08 // example working PSP command line:*
*// ffmpeg -i testinput.avi -f psp -r 14.985 -s 320x240 -b 768 -ar 24000
-ab 32 M4V00001.MP4*

 As I know, ffmpeg -f is used to force output format, but if we still need
to set frame rate, resolution, bit rate.etc when converting to a PSP
compatible mp4, what -f psp does for us?

Thanks
