How do I create an mp4 file from a collection of H.264 frames and audio frames?

Question

I have a program that captures and stores H.264 encoded video as well as audio into a proprietary format file. I need to be able to export that video and audio to an mp4 file. I prefer C# but will use C++ if necessary. Any suggestions?

Answer 1

To produce MPEG-4 Part 14 .MP4 file you need a multiplexer. There is a choice of multiplexers out there:

• FFmpeg (libavformat)
• DirectShow filters (free and open source from GDCL, commercial)
• Windows 7+ Media Foundation file sink

API and complexity might vary because some of multiplexers are expected to be a part of pipeline, they are not completely standalone classes. You might want to check respective samples (and license agreements, perhaps, too) to see what is best for you.

Answer 2

Take a look at libmp4v2. Fairly straightforward to use..
