Comment (by JEEB):
14496-15, 3rd edition is not yet finished
([http://www.iso.org/iso/home/store/catalogue_ics/catalogue_detail_ics.htm?csnumber=65216
link]). Because of various seemingly political reasons, the FDIS ballot
still hasn't been gotten through with, even though the drafts haven't
gotten any major edits since last summer.
Both GPAC and L-SMASH support muxing with the way that's noted in the
draft that was going to be pushed to the FDIS ballot. L-SMASH disables it
in the command line application for now as it's not official yet (although
it's a simple case of switching a #if 0 to #if 1 to re-enable it).
Thanks to the way how extradata for AVC and HEVC is handled in
libavformat/-codec (or more like, isn't handled), you would have to write
bitstream filters similar to AVC's to convert to and from Annex B from and
to the 14496-15 extradata format. For example, MPEG-TS contains HEVC in
Annex B format, while you need it in a different format to mux it like
noted in 14496-15.
