frontends/va: Derive image from interlaced buffers
Allow vaDriveImage to derive a vaImage from interlaced buffers by creating a new progressive buffer. v2: Keeps the surface used by DeriveImage untouched (Pierre-Eric) v3: Fixed a segfault reported by Roman Elshin Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/1428 Signed-off-by: Thong Thai <thong.thai@amd.com> Reviewed-by: Leo Liu <leo.liu@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5942>
