PS. It says that mpeg4 with Simple Profile works on PSvita,
so I convert it with
ffmpeg -i /usr/share/video/example.rmvb -c:a copy -c:v mpeg4 -aspect:v 16:9 -pix_fmt:v +yuv420p -map_metadata -1 -metadata title"mpeg4-test" /var/cache/ffmpeg/example-out2.mp4
The conversion is at the lightning speed and looks with the low quality(lots of q=31), anyway here is ffprobe
...
Stream #0:0(und): Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yub420p, 1280x720 [SAR 1:1 DAR 16:9], 631 kb/s, 24fps, 24tbr, 12288 tbn, 24 tbc(default)
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100Hz, stereo, fltp, 191kb/s (default)
Don't know if this mpeg4 version works well on PSvita, need experiment later...
with love,

Hello all,
I am new to ffmpeg and have weird problem converting video for psvita,
The result of converting failed to seek-to or play-consistent after about 30mins,
I do not think it's the problem with my command or ffmpeg, cuz the video-out works smoothly on my PC
anyway here they are:
ffmpeg -i /usr/share/video/example.rmvb -c:a copy -c:v libx264 -aspect 1:1 -aspect :v 16:9 -pix_fmt:v +yuv420p -map_metadata -1 /var/cache/ffmpeg/exampleout.mp4
FYI,
`ffprobe /usr/share/video/example.rmvb`
...
