+Subject: [PATCH] libs: decoder: release VA buffers after vaEndPicture
+
+This change is due a problem decoding JPEGs with Intel's media-driver:
+no image was generated.
+
+This patch relases the VA buffers after vaEndPicture() is called,
+and not before (after vaRenderPicture()).

+
+Upstream-Status: Backport [https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/commit/bb8894aaf934b3af4d44cf54e860510fe4d615b3]
