playing and parsing mpeg2ts file

[Duchassin Frederic]

: 	Sorry Tim,

I was too fast for may answer. Next time, i'll be carefull to answer to the list.
Even with max-size-bytes=0 max-size-buffers=0 max-size-time=0 for tsparsequeue it doesn't work.
Attached the dot file.

Hi,

Please reply to the list next time

What I forgot to write was: you can just unset all the limits on the
queue in front of tsparse, that should be fine (so max-size-bytes=0
max-size-buffers=0 max-size-time=0).

Cheers
