Nicolas Dufresne	e7b962d9b5	alphacombine: Ignore all events coming from the alpha_pad ... As per usage of this element, everything from this pad is a duplicate. Instead of implemented needless aggregation, simply drop all events from this pad and let the one from the main stream passthrough. Also stop proxying some queries from the alpha pad_too. This fixes racy test failure: - validate.file.playback.scrub_forward_seeking.opus_vp9-alpha_webm Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2247>	2021-05-14 14:11:39 -04:00
Nicolas Dufresne	1229257ad4	alphacombine: Implement flow return propagation ... The EOS handling was not the problem way. Instead of this, implement proper prorogation of the flow return for the alpha chain function.

Nicolas Dufresne	2cd927435c	codecalpha: Implement alphacombine element ... This element will merge video buffers in order to use the alpha stream luma plane as the alpha of the video stream. The implementation is zero-copy and currently only support merging I420 stream with an I420, NV12 or GRAY8 alpha stream.
