Bug #3577
TVHeadend soft-cancels recording of show after a certain sequence of events with recording and live TV (explained in description)
100%
Description
I have discovered a certain sequence of events that can "soft-cancel" a recording in progress. (TVHeadend still indicates that the recording is in progress, but the tuner is freed and the file size no longer grows.) The sequence of steps, for a two-tuner system, is as follows:
- Start watching two channels live. I used Kodi with kodi-pvr-hts 2.2.13, but it may not matter.
- Start recording a third channel, which will preempt the tuner for one of the channels you are watching live.
- Start recording on the channel that was preempted in step 2. This will preempt the other tuner, leaving both Kodi instances stopped with a static image and both tuners recording.
- Press the stop button on the Kodi instance that was playing the channel you began recording in step 3.
You can then see that the recording on the channel from steps 3 and 4 still appears to recording, but the file size no longer grows and one of the tuners is freed. The proper behavior would be to continue recording.

Updated by Further testing indicates that after step 3, there are four subscriptions present as I would expect. Two of them are for the channel from steps 3 and 4 that was previously preempted from live TV but is now recording, one for the live TV and one for the recording. When I stop the live TV session, the live TV subscription disappears and the recording subscription stays, but the tuner is freed anyway so the recording stops.
