IMX8M : aiurdemux and MPEG2TS

[fredericduchass]

Hello,

Is it possible to catch the mpeg2ts dvb-si table (PAT, PMT, SDT, NIT) from aiurdemux  ?

tsdemux can do this feature but there is a problem with tsdemux because the decoding is stopping after few seconds. (aiurdemux works perfectly for decoding)

Hello,

Excuse me if it wasn't very very clear...

I don't want to record the stream; i just want to play it and get the DVB tables (SDT,NIT...)

This is my pipeline :

gst-launch-1.0 pciesrc ! queue ! decodebin name=d d. ! queue ! kmssink d. ! queue ! audioconvert ! alsasink

The source is an MPEG2TS stream. I just switch  between aiurdemux and tsdemux by changing the ranking.

With aiurdemux : i can play video smoothly, but i can't catch DVB tables (GST_MESSAGE_ELEMENT)

WIth tsdemux : i can catch the DVB tables but can't play the video stream

for aiudemux, it maybe not send the DVB table information, for tsdemux, try not to use VPU, to use sw decoder.

Hello Joan,

OK i just would like to be sure aiurdemux can't send DVB table.

I solve the problem using tsparse with a tee in front of aiurdemux. But it increase CPU consumption!
