ci: Disable werror for documentation build

The documentation build is running on an ancient Fedora 30 image that
cannot be updated at present, and it's now triggering deprecation
warnings in system headers:

https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2568#note_1418956

Disable werror here, it's not actually useful.

clock: Use g_atomic_rc_box for refcounting entry clocks

can fix the FIXME and use this.

qsvencoder: Do not copy if input is D3D11 texture

In case that input is D3D11 texture, QSV seems to work regardless
of the alignment. Actually the alignment requirement seems to make
only sense for system memory.
Other Intel GPU dependent implementations (new VA encoder, and MediaFoundation)
do not require such alignment nor other vendor specific ones (NVENC and AMF)

-bad/docs: be more selective about header files to exclude

A few header files in -bad contain comments that start with the
/** gtk-doc pattern, but should not actually be parsed (and warned
about as such).

Previously, we were using far-reaching wildcard patterns to avoid
parsing those, but this had the unintended side effect of also
excluding legitimate files, and creating confusion when comments
were not parsed from those.

Switch to excluding specific files instead.

osxaudio: support hidden devices

macOS features hidden devices. These are devices that will
not be shown in the macOS UIs and that cannot be retrieved
without having the specific UID of the hidden device. There
are cases when you might want to have a hidden device, for example
when having a virtual speaker that forwards the data to a virtual
hidden input device from which you can then grab the audio.
The blackhole project supports these hidden devices and
this patch provides a way that if the device id is a hidden
device it will use it instead of check the hardware list of devices
to understand if the device is valid.

is not any msdk_allocator (i.e. msdk_video_allocator,
msdk_dmabuf_allocator and msdk_system_allocator). Otherwise, when using
pipeline "msdkh264dec ! vah264enc !" to transcode a not 16-bit-aligned
stream (i.e. 1920x1080), the transcoding will fail due to the size
mismatch issue between decoder pool and encoder pool.

gtk: Fix double-free when OpenGL can't be initialised

gtk_gl_area_get_error() doesn't return a copy of the error, but just the
error. If initialising OpenGL fails, then GtkGstGLWidget will consume
the error, and cause GTK to try and display freed memory.

aacparse: Avoid mismatch between src_caps and output_header_type

If our downstream caps didn't intersect, we attempted to convert between
raw and ADTS stream formats, if possible. If the caps still did not
intersect, we then used the modified `src_caps` but left the
`output_header_type` unmodified.

This caused a mismatch between caps and actual stream format.

Avoid this by first copying the `src_caps` to `convcaps` for the
additional intersection tests, replacing `src_caps` if we succeed.

While we're here, clean up the code a bit and remove the `codec_data`
field from outgoing ADTS caps.

amfencoder: always empty the queue when pushing output samples

queueing up in AMFComponent whenever QueryOutput() returns AMF_REPEAT
(and do_wait is FALSE). This has negative impact on latency when the

va: encoder: Fix regression since commit 2042c2d4f0.

There's no need to compare with the open entrypoint to query the
encoder. This commit removes the checks to the configured entrypoint
with the parameter.

rtpptdemux: Don't GST_FLOW_ERROR when ignoring invalid packets

https://bugzilla.gnome.org/show_bug.cgi?id=741398 changed
rtpptdemux in 2014 to not post a GST_ELEMENT_ERROR on the
bus when dropping an invalid (non-RTP) packet, but still
returned GST_FLOW_ERROR upstream - so the pipeline still
stops, but now without a useful bus error.

Return GST_FLOW_OK instead, so the pipeline keeps
running. Some old telephony equipment can send invalid
packets before the real RTP traffic starts.

We prefer black color as an initial texture color and

va: encoder: Do not reset the frame count when reconfig().

We should not reset the input/output_frame_count when some configure
changes. For example, the if resolution changes, the current way just
resets the frame count and make the PTS of the output buffer restart
from the original PTS of the first frame. That causes a lot of QOS
event and drop all the new frames.
We should only reset them when encoder start().

playbin3: Configure combiner on pad-added if needed
