[Libav-user] Change the Stream Info and Codec of MP4 file using FFMPEG muxing / remuxing code

[Ganesh kumar]

Hai friends

I was working project to change the Stream information and Codec
information of mp4 file. is it really possible change the stream
information and codec information using ffmpeg muxing/remuxing code?

For example:
consider the file type
1. major brand:isom
2. compatible brand: isommp42
3. resolution: 1280*780

convert to that file into

1. major brand: mp42
2. compatible brand: isomAVC1mp42
3. resolution: 355*288

Thanks
