So, here's roughly what I think happens (schematically):
- playbin contains, say,
- bin1 with the source and decoder
- bin2 bin with volume ! audioconvert ! audiosink
now, the source posts a DURATION message, which clears all cached durations for
bin1 and then clears all cached durations for bin2. However, the cached
durations from bin2 will not be cleard. So then, next time one does
gst_element_query_duration (playbin, ....)
there is no cached query, so the bin will pass the query on to its children. If
that child is bin2, it will return the outdated previously cached query.
Not sure what the right solution for this is. Maybe have all elements post a
duration message on the bus whenever they come across a NEW_SEGMENT event
maybe? Or introduce some kind of gst_bin_clear_cached_durations() which a bin
calls on all children that are bins after clearing its own cached durations.
