[FFmpeg-user] Mux encoded video data directly into mp4 files

[fernando.takeshi]

Hi, thank you for your time and response.

What I meant is, with the linked sample data I supplied previously, I tried
the following:

mjpeg.hex: Invalid data found when processing input


But that was just a simple test. I need to do this programatically. What I'm
really looking for is the sequence of commands required to mux raw data
(h264, mpeg and mjpeg frames) into mp4 video files, skipping encoding so the
output is produced as fast as possible. It seems every search I do on the
topic turns up different functions and orders to accomplish this!
