Using h264 and aac, I've been trying to generate an mp4 and mpegts output in one command using the new tee muxer.
Either it complains about a lack of the aac_adtstoasc bsf, or if global_header is set a lack of the h264_mp4toannexb bsf. However, I can find no way to add a bsf for one output and not the other: adding it as usual applies to both outputs, and the muxer options (between
) do not accept bsfs.
Did the ffmpeg team a) document this feature poorly or b) render this combination of outputs impossible?
