Tvheadend

Could you explain a bit more what hangs? Debug log might give a clue.

I'm not sure which debug subsystems to start (I used: main,muxer,service,channel,service-mapper), so I am not sure if this tells you anything. Please advise if you need other information!

For this test, I selected 3 channels: 2 regular TV channels and 1 on which tvheadend fails (Humax 5300 dev) and selected: 'map selected services'. tvheadend starts with mapping the last but never continues to the next channel. The progress bar in the status screen shows: 0 / 3, but no progress as well

Could you retest with v4.3-1487-gef939ad18 ?

v4.3-1492-g476ed21c0 ?

The watchdog kicks in after 30 seconds, but the total time apparently is too long for the service mapper, as the website return to the default page. You need to (re)start the service mapper again. I'm not sure if this is the best solution. After the service-mapper has gone through all of these specific services, the other services are mapped correctly.

If I look into the details of the service, I can see that these have a specific service type of 128. I do not know if this is a general rule (or not). If so, isn't it easier to check for this service type and skip mapping if equal? Unfortunately, I am not a developer...

I tried to improve the code in v4.3-1494-g26dc2643e - there's a check for A/V streams after 5 seconds and the mapper breaks the loop when no A/V streams are detected in PMT.

Anyway, there is no timeout in webui - if you got the default page, it usually means that the whole tvheadend was restarted for a reason.

What I mean is that the gui returns to the EPG page after a while. I have not restarted tvheadend. When then returning to the status page to look at the progress of the mapping process, it shows 0 / 0 and the Services tab confirms that no additional services are mapped.

I will give 1494 a try and get back to you

Just tried 1494. tvheadend gui freezes. Syslog shows the following:

Oct 22 21:41:33 meter tvheadend[7976]: mpegts: too much queued input data (over 50MB) for DRXK DVB-C DVB-T : DVB-C #0, discarding new

If required, I will make a dump. But that will be tomorrow at least...

Locking issue: Try v4.3-1495-g7ad64f712.

Retested with 1495: works perfect! Thanks!
