[vlc] MPEG2 transport stream handling ??

[Moody, Paul G]

Hello,
	Q1	when I feed a multiplex TS stream to VLC it cannot process the TS unless it begins exactly on a packet header ... ie 0x47 sync byte. For instance my test file mpeg2.ts had 36 bytes of data before the first valid packet header. I had to dd if=mpeg2.ts of=mpeg2A.ts bs=36 skip =1 to 'clean' off the 36 bytes before VLC would play the stream. Additionally the stream breaks if there are further missing syncs /short packets /long packets in the stream. In real life there is never a clean feed unless you are at the studio :).

	Q2	how do I select a particular program ( video + audio ) PID from the multiplex TS. VLC seems to pick out the first one it finds and play that. For that matter  how do I  see the contents of the multiplex stream. ( is there a demux / PSI process ?)

	Q3	How do I feed  VLC from a pipe? I used a mkfifo pipe however VLC keeps reporting EOF and buffer writes / possible memory leak. It works beautifully from a file but not a pipe .. Huh ?.

	Q4	Looking through the code there seems to be multiple threads running ... is there some  sort of architectural diagram describing the thread interactions ? 

PS my thanks for an excellent project.
