Muxing elementary streams

[TCmullet]

I have a pair of files, elementary streams.  One is video with ".264", and the other is audio, ".ac3".  I can't figure out how to make Avidemux mux them together into a transport stream.  What am I missing?

If Avidemux can load the video, you can add audio from the "Audio" menu: "Select Track" --> Track 1 (x) Enabled --> [...Add audio track]. If Avidemux can't load the video because it is really a raw video stream: use ffmpeg. The following command should do it:

Code Select Expand

ffmpeg -f rawvideo -pixel_format PIXEL_FORMAT -video_size WIDTHxHEIGHT -i your_raw_video_stream.h264 -i your_audio_stream.ac3 -c copy output.mkv

If the pixel format is yuv420p (the default value), you can omit -pixel_format completely.

The first option worked well.  Amazing what features might lie hidden somewhere.  I never would have turned on the check mark as I thought that was for selecting existing ones.  Thanks very much, Eumagga0x2a!
