Your patch doesn't look right to me - it still results in an update=FALSE
segment being sent when it receives an update=TRUE segment. Why is it doing it
My case is specifically that update=TRUE new segment events MUST be forwarded
(I only really tested with single-stream audio files - so the selector isn't
actually doing any meaningful selecting)
- using playbin2
- some element sends a closed (i.e. has valid start AND stop) new-segment
- later, said element decides it didn't actually want that segment to have a
valid stop time. So it sends an update-new-segment that is the same as the
original one, but with stop=GST_CLOCK_TIME_NONE
- current input-selector forwards this as a new, update=FALSE, new-segment -
so the old segment with the incorrect stop time is still used.
- my patch makes it preserve the update flag
Something like your patch might be needed too - I think we're actually seeing
different problems with vaguely-related underlying causes, and we need to fix
both things. I'm not entirely convinced that I understand new-segment semantics
(particular for sparse streams) well enough to fix this properly.
