[FFmpeg-user] how do I set configuration the H264/MPEG4 in decoding?

[SON NAM RYE]

Hi All!

 

Whenever I have compiled the ffmpeg, sizes of created files are different.

In testing, memory occupancy and cpu performance are different according to
those.

 

I just want to decode H264 and MPEG4. How do I set configure?

My configuration and ffmpeg version are as following:

ffmpeg version 0.11.1 Copyright (c) 2000-2012 the FFmpeg developers
