Summary of the bug: When copying a m2ts HE-AAC stream to mkv conteiner, the output file contains audio codec format 1602 instead of HE-AACv2 / HE-AAC / LC. ID do Codec : 00001000-0000-0216-8000-00AA00389B71 For the documentation of the undocumented generic options, see the Codec Options chapter.

OBS would specify the inputs and ffmpeg process them.ġ) setup on Setting > output > recording > Output to URL Maybe a way to implement all this in a single stroke would be the ability to pipe OBS with ffmepg scripts: The tee muxer does a single encode for all the outputs so it is better for the CPU. The tee muxer is quite convenient in that it enables multiple outputs.Ĭase_use: This would allow streaming to various destinations, URL and files (streaming and recording).Ĭase_use: this would allow more muxing options (the video and audio streams can be muxed differently on the various tee muxer outputs) This can be useful for mepgts or mkv (multi-language) for sdi embedded audio inputīut all the filters of ffmeg are available. ![]() ![]() This command separates for instance a 7.1 sourround audio in 8 streams ( video stream).
