How to pack raw data (h.264) to mp4 (C#)?

Question

.NET

Hello. I have this situation: I receive video from an IP camera via the RTSP protocol, write the received bytes to a file and get raw h.264. The file is played, but it is not good to store it in its naked form.
Tell me, who knows how to pack this raw data (h.264) into mp4?
Using C#

Answer 1

ffmpeg -i "source.h264" -c:v copy -f mp4 "myOutputFile.mp4". I suppose you can run ffmpeg through the system.diagnostic.process api or use a wrapper.

Answer 2

Process.Start("ffmpeg.exe", "params");
