yes i used mediainfo, this is the info for the working file:

Format profile : Simple@L3
Format settings, BVOP : Yes

FFmpeg gives this type:-

Format profile  : Simple@L1
Format settings, BVOP   : No

I don't know if it's possible to change it.

[Chris K]

Try to add this ...

-profile 0 -level 3 -bf 2

[bat999]

Try to add this ...

-profile 0 -level 3 -bf 2

Yes, that does the job.

This is the command I used:-

ffmpeg -i filename -vf "scale=320:trunc(ow/a/2)*2" -c:v mpeg4 -b:v 400k -profile 0 -level 3 -bf 2 -c:a aac -strict -2 -b:a 128k -ar 44100 -ac 2 filename.mp4

Yes! Only my recent FFmpeg version recommends to use -profile:v instead of -profile. It will probably taken off in a while.

EDIT:

I knew it had a reason so I looked it up again. Libfaac supports profiles and FFmpeg has to know for which encoder the command is meant.

This are the ones I know of ...

-profile:a aac_low (LC) and -profile:a aac_main

[rekotc]

it worked! ..thanks a lot for your help!

[rekotc]

ok one more question, i see that the codec ID is 'isom', is there any way to change it to 'mp42' ?

[poisondeathray]

Does your phone have problems with it? Why do you want to change it ?

If you use ffmbc instead of ffmpeg, or just re-wrap what you have with ffmbc, it uses mp42 for mp4 container instead of isom

[rekotc]

yes my phone refuses to load the file..it shows a generic message: wrong file format or too high bitrate, and i know the problem is not the bitrate, so i thought it may be connected to the codec ID..i try with ffmbc thanks

[poisondeathray]

If that's not the reason and it still doesn't work, there can be other reasons and/or differences for it not working . eg. max consec b-frames length, gop size

If you temporarily remux the working video into avi container (no audio), and use gspot, it will provide more information on the xvid settings used (it actually scans the file, where as mediainfo just reads the header)

ffmpeg -i input.mp4 -vcodec copy -an output.avi

[Chris K]

ok one more question, i see that the codec ID is 'isom', is there any way to change it to 'mp42' ?

mp42 is the MS implementation of the mpeg4 codec. FFmpeg supports it but not in the mp4 container. If your phone supports the avi container you could give it a try. the codec is -c:v msmpeg4v2 but it also doesn't support b-frames so you would have to try it plain as it is.

ok i finally got a solution, the phone (samsung s5230) plays videos with the following characteristics:
