Nicolas Dufresne	e70993bf43	v4l2codecs: Wait for buffers to come back ... This code add required mechanism to try and allocate (not implemented yet) otherwise wait for more buffers. This also comes with mechanism to terminate the wait on flush or PAUSED_TO_READY transitions.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	bc0a8ff40d	v4l2codecs: pool: Create new buffer when pool is empty ... This simply create an empty GstBuffer when the pool is empty. This way it's up to the allocator to grow or wait if we ran out of memory.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	3c2d25eebf	v4l2codec: Add initial GstVideoMeta support ... In this patch we strictly set the GstVideoMeta width/height to the coded width and height. Further patches will add stride support and frame copying when downstream does not support GstVideoMeta.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	db787adfa1	v4l2codec: Add getter for buffer index in allocator and pool	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	c120f8b041	v4l2codec: Add allocator and pool implementation ... This is a pooling allocator and the buffer pool does nothing other then reusing the GstBuffer structure. Note that the pool is an internal pool, so the start/stop/set_config virtual functions are not implemented.	2020-03-31 09:34:05 -04:00
