[FFmpeg-user] Muxing raw H264 to container format (MP4, MOV)

[oblivion]

Hi,

> ffmpeg -threads 3 -i in.h264 -vcodec mpeg4 -r 25 -sameq outfile.mp4

Thanks  for the help, but as I said I don't want to recompress it, I just
want to mux the original encoded video stream in a container to get seeking
information (hence the "-vcodec copy"). 

I know it works because avc2avi does it, but it outputs AVI 1.0 and I need
AVI 2.0 (or mkv or mp4). I know the video content is ok because I can play
it in vlc and I can read the h264 packets in code.

The stream is at about 24fps but that is not the problem really. I can tweak
the frame rate if I get the file to actually mux in the container.

There is no sound. The original file is just a raw h264 stream from a
hardware device. I don't need to mux sound in the container at the moment
anyway.

The output is one stream, as expected:

Input #0, h264, from 'Anonymous-3-recording.h264':
  Duration: N/A, bitrate: N/A
    Stream #0:0: Video: h264 (High), yuv420p, 1280x960, 25 fps, 25 tbr,
1200k tb
n, 50 tbc
