This gem has been disabled since 2001.

The lowest supported VAAPI version is 0.34 (checked at configure
time), so this test is no longer needed.

If no string argument is supplied when av_hwdevice_ctx_create() is
called to create a VAAPI device, we currently only try the default
X11 display (that is, $DISPLAY) to find a device, and will therefore
fail in the absence of an X server to connect to.  Change the logic
to also look for a device via the first DRM render node (that is,
"/dev/dri/renderD128"), which is probably the right thing to use in
most simple configurations which only have one DRM device.

Unbreak `avconv -filter_complex testsrc`.

This will be needed for frame threading.

We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.

This prepares the decoder for frame threading support.

Not from the underlying frame. Fixes races with frame threading in
field-coded files, where decoding would wait for the wrong field (e.g.
random failures in mixed-nal-coding).

Bug-Id: 954

Fixes memory leaks in some FATE tests.

A non-existent av_buffer_pool_can_uninit() function is mentioned instead
of av_buffer_pool_uninit(). Also, this function is to be called by the
caller, not the pool itself.
