Tvheadend

I would recommend to use other TS tools to analyze streams like tsduck or dvbsnoop . Just capture the mux or a service or subscribe requires pids (mux url and pids=<list> as http argument).

That was my first thought, however, the device i use a Wetek Play 2, their wonderful developers have abandoned the device. They proprietary drivers. Some people over at the coreelec team use some open source/custom driver that is better. However they do not contain DMX_FILTER option which dvbsnoop needs in order to get the output. Just thought it might have been a quick code adjustment to add more output from information that is already being read

You can just save the MPEG-TS output from tvheadend to a file and use those analyzers (both can use the input from a file instead the real DVB device).

So I can simply record a channel to a .ts file and feed that file into an analyser, and it should pick up all the tables?

I was not aware of that. Didn't think that .ts contained those streams. Thought it was only video audio and subs streams.

I will give it a shot

So I just tried it and I may be out of my depth here. When I have run dvbsnoop in the past, I can get a hex output filtered on the sdt table using:

dvbsnoop -s sec -tn -ph 2 -pd 4 -f 0x42 -m 0xFF -n 5 0x11

When i then replace that with the recorded .ts file,

dvbsnoop-s ts -if file.ts -ph 2 -pd 4 -f 0x42 -m 0xFF -n 5 0x11

I get no output. Only way is to remove "0x11" but that does not give me what I am looking for.

What am i missing. Does it not output this table correctly?

That was suppose to be, dvb -tssubdecode
