Video encoding MPEG4


I had recently purchased a mobile phone that is supposed to be able to play mp4. After purchasing the mobile, noticed that I am unable to play the mp4 file. Upon clarification, I understand from sonyericsson that MP4 is a general category, and only video encoding MPEG4 can be viewed on on the mobile phone.

1. A file with an MP4 file extension, how do I check what is the actual video encoding?

2. How to convert the non-MPEG4 video encoded file to one that is MPEG4 video encoded?


Thanks in advance.

There still seems to be some confusion here:

mpeg4 is an mpeg 'wrapper'. mpeg4 may contain several different codecs including Xvid, h.264, and DiVX. My 'guess' is that Sony (being as proprietary as they are) have a specific codec that your phone can play, and you must use their software to encode to that codec (or find out what it is and find an application that allows the option to encode using that codec). To further the problem, when the PSP was first released there was some talk about file naming structure, this may also be the case with your phone. It may need a special nomenclature for the filename to even "see" the file.

My suggestion:
If you have a video that can play on the phone, throw it on your computer. Use mplayer to identify the video type and codec used, and then try encoding your video with similar parameters.

Good luck!

Cool
