[FFmpeg-user] Weird problem converting video for PSvita,

[gene0mega]

PS2. The example-out2.mp4 seeks well and play smoothly on PSvita,
but with only 1/2 quality of the origin one(631 versus. 1201)

PS3.error at 1st mail:
`ffprobe /var/cache/ffmpeg/exampleout.rmvb`
to
`ffprobe /var/cache/ffmpeg/exampleout.mp4`

with love,dye

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`
...
Stream #0:0: Audio: aac (raac / 0x63616172), 44100Hz, stereo, fltp, 192kb/s
Stream #0:1: Video:rv40 (RV40 / 0x30345652), yuv420p, 1280x720, 1201 kb/s 24fps, 24tbr, 1ktbn, 1k tbc


`ffprobe /var/cache/ffmpeg/exampleout.rmvb`
...
major_brand: isom
minor_version: 512
compatible_brands: isomiso2avc1mp41
Stream #0:0(und): Vedio: h264(High) (avc1 / 0x31637661), yuv420p, 1280x720[SAR 1:1 DAR 16:9], 891 kb/s 24fps, 24tbr, 1572867.00 tbn, 48tbc(default)
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100Hz, stereo, fltp, 191kb/s (default)


`ffmpeg -version`
...
ffmpeg version N-62992-g89d2fc6
