In general, installing ffmpeg supposed to be straight forward. More general info on ffmpeg is available at. Video encoder and audio encoder are then : mp2Ģ) locate your profile folder or : File > Show Profile folderĤ) edit as follows the basic.The best site as a reference of compiling ffmpeg on Ubuntu is Ubuntu Compilation Guide. 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).

One would need to pass options to ffmpeg here: ffmpeg -i INPUT -c:v -c:a -f muxer OUTPUTĮx: ffmpeg -channels 8 -f decklink -i Decklink-INPUT -filter_complex 'pan=mono|c0=c0 pan=mono|c0=c1 pan=mono|c0=c2 pan=mono|c0=c3 pan=mono|c0=c4 pan=mono|c0=c5 pan=mono|c0=c6 pan=mono|c0=c7' / (3) enable custom filter options on ffmpeg input:Ĭase use: -filter_complex on audio and video Ĭase use: surround audio recorded in different channelsĬoupled to mpegts (see (1) ), this is useful in professional settings (stb iptv dvb) (2) increase the number of audio tracks to at least 16 or better 32:Ĭase use: SDI with embedded audio (16 channels usually) corresponding to various languages, commentary, etc. (1) better codec selections (at least for mpegts):Īt the moment when selecting any given muxer in recording > Custom Output (FFmpeg), a default encoder is selected but there is not always freedom to select another compatible codec.Įx: mpegts => video encoder is only mpeg2video and audio encoder is: mp2īut mpegts is compatible with x264 and aac. This is a series of suggestions for a better use of ffmpeg capabilities.
