Mathieu Duponchelle	62d1a3a143	cccombiner: don't drop buffers on video timestamp discontinuities ... If we receive video buffers with non-perfect timestamps, the caption buffers' timestamps might fall in the interval between the end of one video buffer and the start of the next one. Make our criteria for dropping that the caption buffer has a timestamp older than the end of the previous video buffer, not older than the start of the new one, unless of course this is the first video buffer.

Sebastian Dröge	92dd72b7ee	cccombiner: Make use of new GstAggregator::negotiate() ... Simplifies the caps handling code considerably here and removes some spurious negotiation.	2019-08-14 17:37:59 +00:00
Mathieu Duponchelle	74d281fbc2	cccombiner: implement update_src_caps ... It is necessary to implement this vmethod, as when the src pad is marked as reconfigure, the base class will reset to src caps, and the default update_src_caps simply queries the caps allowed downstream without taking into account the caps set by gst_aggregator_set_src_caps.	2019-02-28 17:03:33 +00:00
Sebastian Dröge	eb92865ea1	cccombiner: Add new closed caption combiner element ... This is the inverse of ccextractor: it takes a video and closed caption stream and places the closed caption metas on the video output buffers.	2018-11-06 16:21:42 +00:00
