abfb5dd06c vaapidecode: parse source data until a frame is obtained.
Parse any pending data until a complete frame is obtained. This is a
memory optimization to avoid expansion of video packets stuffed into
the GstAdapter, and a fix to EOS condition to detect there is actually
pending data that needs to be decoded, and subsequently output.

cb81acd48c vaapidecode: add system memory caps to template caps.
Since vaapidecode provides buffer that can be mapped as regular memory,
those caps should be added to the template caps. That only applies to
GStreamer >= 1.2.

d2f6274f31 vaapidecode: fix hang on SIGINT.
vaapidecode hangs when pipeline is stopped without any EOS, e.g. when
<Ctrl>+C is pressed, thus causing the srcpad task to keep running and
locked. This fixes a deadlock on state change from PAUSED to READY.

6b6c10d94d plugins: request GLTextureUpload meta on buffers in the buffer pool.
Requesting the GLTextureUpload meta on buffers in the bufferpool
prevents such metas from being de-allocated when buffers are released
in the sink.

This is particulary useful in terms of performance when using the
GLTextureUploadMeta API since the GstVaapiTexture associated with
the target texture is stored in the meta.

a6436f27d5 vaapidecode: fix decoder flush.
There are situations where gst_video_decoder_flush() is called, and
this subsequently produces a gst_video_decoder_reset() that kills the
currently active GstVideoCodecFrame. This means that it no longer
exists by the time we reach GstVideoDecoder::finish() callback, thus
possibly resulting in a crash if we assumed spare data was still
available for decode (current_frame_size > 0).

Try to honour GstVideoDecoder::reset() behaviour from GStreamer 1.0
that means a flush, thus performing the actual operations there like
calling gst_video_decoder_have_frame() if pending data is available.

367944ba32 vaapidecode: drop decode timeout, always wait for a free surface.
vaapidecode used to wait up to one second past the expected time of
presentation for the last decoded frame. This is not realistic in
practice when it comes to video pause/resume. Changed behaviour to
unconditionnally wait for a free VA surface prior to continuing the
decoding. The decode task will continue pushing the output frames to
the downstream element while also reporting errors at the same time
to the main thread.

7e8470e1ec vaapidecode: fix srcpad caps for GStreamer 1.2.
The srcpad caps exposed for GStreamer 1.2 were missing any useful info
like framerate, pixel-aspect-ratio, interlace-mode et al. Not to mention
that it relied on possibly un-initialized data. Fix srcpad caps to be
initialized from a sanitized copy of GstVideoDecoder output state caps.

Note: the correct way to expose the srcpad caps triggers an additional
issue in core GStreamer auto-plugging capabilities as the correct caps
to be exposed should be format=ENCODED with memory:VASurface caps feature
at the minimum. In some situations, we could determine the underlying
VA surface format, but this is not always possible. e.g. cases where it
is not allowed to expose the underlying VA surface data, or when the
VA driver implementation cannot actually provide such information.

underlying VA surface format, or if it is actually not allowed to get

a00ae0918a plugins: cope with new GstVaapiVideoMeta API.
Update plugin elements with the new GstVaapiVideoMeta API.

This also fixes support for subpictures/overlay because GstVideoDecoder
generates a sub-buffer from the GstVaapiVideoBuffer. So, that sub-buffer
is marked as read-only. However, when comes in the textoverlay element
for example, it checks whether the input buffer is writable. Since that
buffer read-only, then a new GstBuffer is created. Since gst_buffer_copy()
does not preserve the parent field, the generated buffer in textoverlay
is not exploitable because we lost all VA specific information.

Now, with GstVaapiVideoMeta information attached to a standard GstBuffer,
all information are preserved through gst_buffer_copy() since the latter
does copy metadata (qdata in this case).

Make sure to push all decoded frames downstream as soon as possible.
This makes sure we don't need to wait for a new frame to be ready to
be decoded before receiving new decoded frames.

This also separates the decode process and the output process. The latter
could be moved to a specific GstTask later on.

Make vaapidecode derive from the standard GstVideoDecoder base element
class. This simplifies the code to the strict minimum for the decoder
element and makes it easier to port to GStreamer 1.x API.

4bcfa3fe0a vaapidecode: adopt non-deprecrated glib locking primitive pattern.
The use of heap allocated GMutex/GCond is deprecated. Instead place them
inside the structure they are locking.

These changes switch to use g_mutex_init/g_cond_init rather than the heap
allocation functions.

Because we cannot test for a NULL pointer for the GMutex/GCond we must
initialise inside the GObject _init function and clear inside the _finalize
which is guaranteed to only be called once and after the object is no longer
in use.

Reset, i.e. destroy then create, the decoder in _setcaps() handler only

to be more tolerant with certain MPEG-2 streams that get parsed to
form caps that are compatible with the previous state but minor changes
to "codec-data".

7a0382130f configure: drop check for --enable-vaapi-glx.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.

Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.

d43f3dc50a decode: delay NEWSEGMENT event if vaapidecode element was not linked.
Rationale: playbin2 links all elements at run-time. Once vaapidecode
is created and a NEWSEGMENT event arrives, downstream element may not
be ready yet. So, delay this event until next element is chained in,
otherwise basesink could output "Received buffer without a new-segment.
Assuming timestamps start from 0".
