Description

I've noticed that when some services move or time-share with another service broadcasters will leave the remains of the old service, they often just remove the video & audio from the PMT. Tvheadend doesn't detect this & still sees the service as live.

For example BBC Three in the UK time-shares with CBBC on Freeview between 7pm-5.30am. This is what happens when the video & audio get stolen for CBBC.

Index    PID    Type    Language    Details
     0x1fff /  8191    PCR          
     0x012c /   300    PMT          

After filtering and reordering (without PCR and PMT)
Index    PID    Type    Language    Details
None

Would it be possible to improve checking on services? I've noticed that it takes Tvheadend up to 5-10 seconds for it to declare that there is nothing to stream even though it already knows there is nothing available..

It would also be nice to have a log of when changes occur to a service. For example the dates/times of when a service loses streams. This could be added to the service details dialog.

Opinions? :)

Fixed in v4.1-642-g35c0d91 . I moved the "decision" things to the PMT parser and added the audio/video stream check to be sure that the service is live.
