Which commands did you use? Which Walkman device do you use? – falstaff Sep 9 '11 at 13:52
There might be a few video codecs for MP4 [the only one I can think of is H.264, but I wouldn't be surprised if there were several], but if you look up what what codecs your walkman supports, then you can use the -vcodec flag in ffmpeg to use a specific codec – Matt Sep 9 '11 at 15:04
Have you resolved this question? – pl1nk Jun 25 '12 at 16:26

You can also use MikSoft Mobile Media Converter for the transcoding task, which features pre-loaded Presets for the Sony Ericsson Xperia and/or Vivaz devices, which should be compatible with your Sony Walkman. Additionally you can use several codecs from within the GUI in order to perform an easy transcodification.

Good luck!

I'd suggest HandBrake

You are probably using the wrong codecs, there might be several for MP4.

Take a look at Arista, you can download pre-made conversion presets for Arista from http://www.transcoder.org/presets/, they should be custom-made to include the correct codecs for that device.
