Comment (by jkqxz):

 The leak of VA buffers is due to a difference between the i965 driver and
 the VAAPI specification.  See the descriptions around
 <https://cgit.freedesktop.org/libva/tree/va/va.h#n2262> and
 <https://cgit.freedesktop.org/libva/tree/va/va.h#n2390>, but the i965
 driver does not free buffers after they are passed to vaRenderPicture().

 This is worked around in
 <https://git.libav.org/?p=libav.git;a=commit;h=4926fa9a4aa03f3b751f52e900b9efb87fea0591>
 along with
 <https://git.libav.org/?p=libav.git;a=commit;h=221ffca6314ed3ba9d38464ea50cd85251c04e74>
 for the encoder (both changes pending merge) by detecting the i965 driver
 and having different behaviour in that case.
