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?
