Description

if you look at ts files in https://www.lonelycoder.com/redmine/boards/5/topics/7845 you will see that we do not have the PAT/PMT generated each 1000 packet as expected, that the TS recorded file does not start with the PAT packet.

My TV does not like the TS generated by new TVHEADEND either.

Simply record a file is passthrough mode and run TSINFO on it.

What was happening was that the passthrough muxer was injecting the PMT packet first, followed by the PAT.

I've just pushed a change to master which swaps the order. Does this make your TV happier?

Yes the write order was swapped. But that does not explain the count?

tvheadend outputs the PAT/PMT, then 1000 media packets, then the PAT/PMT, then 1000 media packets...

Problem is that tsinfo output says something else. https://www.lonelycoder.com/redmine/boards/5/topics/7845 "Found 10 PAT packets and 4 PMT packets in 5000 TS packets." Or the output of tsinfo is wrong?

Yes, as discussed in the forum, the tsinfo output is wrong.

Can we now close this issue?

You can close it but I haven't finished testing with the TV. I would like to record channels with EAC3 5.1 audio and make sure it works also. I will probably manage to finish testing over the week-end.
