He Junyan	b5c07e11ca	va: Use a lock to protect the surface copy by using vpp. ... If we use vpp to do the surface copy, its operation is not atomic. We need to maintain the filter's context unchanged during the whole copy progress. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1373>	2021-11-29 19:25:31 +00:00
Víctor Manuel Jáquez Leal	ffa2522fc0	va: Add GstVaSurfaceCopy class. ... This new class is a helper for fast/tricky copy of surfaces. First it tries to copy using the function vaCopy in libva 1.12. If it fails, or it's not available, a GstVaFilter is tried to be instantiated with the allocator's parameters, and if succeed, it's used for copying the source surface. This is required for dmabuf surfaces with drm modifier. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1023>	2021-10-10 17:03:29 +00:00
