This is something I've seen quite a bit and I've finally started to
investigate: if I pause playback of a recording for a long time (i.e.
pause playback to go and do something quick and end up getting
distracted...) when I start playback again, vdr dies. The watchdog timer
expires and it tries to restart but it ends up with one process which
won't die (have yet to work out which thread this is, though).
Not sure if this is a vdr or softdevice problem but seeing the references
to libavcodec I'd be inclined to think softdevice.
I started playback and then paused it for about 2 h or so and then
pressed "play" again. Playback didn't restart. Trying to change channel
then caused the timoeut (or maybe it would have done it anyway). (All of
this was done over shh with SVDRP but this looks like it's doing what I
see 'in real life'.
Here is a backtrace from when this happens:
