AVC Mpeg2-TS problem

[chits007]

Hi,

I am working on ISDB-T system which has AVC/AAC over MPEG2-TS.
I have two problem.

1) The PES_Packet_length is zero ;the standard give permission for it also;so I keep buffering all the payload till I hit next payload_unit_start_indicator;Is my strategy right?

2) I regard all the data in the buffer as ONE frame ;but when I analyse the data I saw that it actually contain 5 video frame .I basically searched for nal_access_unit delimiter 0x09.
I also played back this data in mplayer/vlc ;they also identify 5 frames.
Now my question is where is this 5 figure comes from;Is this any standard on the multiplexor can choose anything ?How do I calculate the PTS of all those 5 frames?

Thanks

You could have edited your title on the other thread.

Sorry, I have no experience demuxing AVC, so I cannot help you.

Now that European HDTV broadcasters have adopted MPEG-4 AVC in .TS format, we could really do with some tools to de-mux these streams.....

chits007, you might have more success asking your questions over in the MPEG-4 AVC (http://forum.doom9.org/forumdisplay.php?f=77) section of the forum!

Maybe this thread could me moved there?
