[MEncoder-users] mpg to mp4 help

[Bill Moseley]

I've got a Sony Walkman player and I'm trying to create videos that will
play on it.  I have an existing movie trailer that does play on it (as
well as in mplayer).

So, I'm trying to convert an mpg from my digital camera to mp4.
This plays fine with mplayer, but not on the Walkman.

Video:
$ mencoder -vf format=i420 -nosound -ovc raw -of rawvideo -ofps 29.970 -o video.raw example.mpg
$ x264 -o video.264 --fps 29.970 --crf 26 --progress video.raw 352x240


Extract audio and encode
$ mplayer -ao pcm -vc null -vo null example.mpg
$ faac --mpeg-vers 4 audiodump.wav

Combine into mp4 container
$ MP4Box -add video.264 -add audiodump.aac -fps 29.970 example.MP4

But, the Walkman says it's a format that it cannot play.
I noted the audio was 44100Hz instead of 48000Hz, and the video sizes
vary.


Here's the output from running my created mp4 and the "Spider
Man" trailer:

Any ideas how to make it work?
