Actually GXF muxer should work if packet containing 65536 samples
and correct dts are supplied, though Im concerned about the mandatory

Now Im thinking that PES packetizer should be made generic to get a
correct TS muxer, and maybe having some sort of mechanism could be
usefull, and IIRC h264 in TS (PS ?) needs strict packetization, maybe
vc-1 will too, and it could avoid bloating TS muxer with special cases.
