hello,
I wonder if I can convert h264 stream so it can be played on my phone.
As I've seen H.264 codec can be played so not sure what's the matter exactly.

With little knowledge to mp4creator I've listed the problem video content:
H264 Baseline@2.1

..and playable video content:
H264 Baseline@1.1

This looks like my phone can't play Baseline@2.x codec.

So my question here, can I somehow change it to Baseline@1.x ?
I have mp4creator and mp4box tools but not much idea what they do, can they do the job for me?
If so, give me please exact commandline format, any help appreciated

i don't think hackering around will work, the difference is to big,

you will have to transode 2.1 to 1.1.

you can use http://mediainfo.sourceforge.net to figure out whats up (there should be for example drastic video bitrate difference if nothing else).
