Hi Gary, A small question/comment regarding one of your statements: Le 05/02/2013 17:49, Gary Hughes a écrit : > [GH] While 13818-1 does not require any specific PES alignment other > than at signaled discontinuities or random access points, many > derivative specifications, such as those from SCTE, DVB, DLNA do > require that AVC AUs be aligned with PES packets. Transport stream > encoders that support cable or IPTV environments will have an option > to produce PES aligned streams, one AU per PES at least for video. DVB [1] only says that alignment *may* be used. And from what I've seen, typical Digital Terrestrial TV streams, at least in France, do *not* use the data alignment in PES packets for AVC streams. Requiring that MSE MPEG-2 TS Segments use it would preclude being able to reuse these DTTV streams as is.
