The PictureRelease function is being overriden by the vaapi_vout module, but
forgot to release the associated picture when refcount reached zero. This results
in a memory leak for the pictures.

The memleak is solved by this patch.

Manual backport of 7fbedf14e

We can't keep the cc decoder serialized with video decoder.
If the decoding delay between packetizer and video decoder is bigger
than caching (for example when using multi threaded decoder), we will
be too late for the next picture display while we wait for the right
rendering time for the CC.
