Stéphane Cerveau	51e93408a9	alphacombine: update example launch line ... Fix typos and missing videoconvert element to demonstrate the alphacombine element. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1494>	2022-01-06 14:59:02 +00:00
Nicolas Dufresne	2886eab3c4	alphacombine: Fix for early allocation queries ... When using playbin3, it seems that the alpha decode is always first to push caps and run an allocation query. As the format change from sink and alpha were not synchronized, the allocation query could endup being run before the caps are pushed. That may lead to failing query, which makes the decoder thinks there is no GstVideoMeta downstream and most likely CPU copy the frame. This patch implements a format cookie to track and synchronize the format changes on both pads fixing the racy performance issue.

Julian Bouzas	bc358e5827	alphacombine: use the same allocation query data for both decoders ... This allows downstream elements to set allocation query parameters for both decoders, which should be always the same.
