e037391364 v4l2object: Avoid colorimetry mismatch for streams with invalid colorimetry 
video-info sets gst colorimetry to default value when colorimetry in caps
is unparsable or invalid. Then v4l2object uses this gst colorimetry to do
mapping with v4l2 colorimetry. This may cause colorimetry mismatch when
check mapped gst colorimetry with that read from caps directly.

To fix this, need to correct gst colorimetry as that parsed from video-info
when check gst_v4l2_video_colorimetry_matches().

4c6ff9fb58 v4l2object: Add support for hdr10 stream playback 
Colorimetry of hdr10 video is bt2100-pq with transfer as
GST_VIDEO_TRANSFER_SMPTE2084. So map GST_VIDEO_TRANSFER_SMPTE2084
to V4L2_XFER_FUNC_SMPTE2084 to support hdr10 stream playback.

V4L2 makes no difference between the BT.601 and BT.709 transfer

fc5a1e468b v4l2videodec: Do not expose profiles/levels in vp8/vp9 template caps 
Vp8/vp9 supported profiles/levels are listed in decoder sink caps, but
there is no parser for these two formats and the demuxers also don't have
these information. It causes negotiation fail between demuxers and decoder
when check caps "accept = gst_caps_is_subset (caps, template_caps);".
To fix this, need to remove profiles/levels for vp8/vp9 formats in decoder
sink caps.

Fix #854

e885e0e1d7 v4l2videodec: fix src side frame rate negotiation 
Negotiating v4l2h264dec ! v4l2h264enc transcoding pipelines fails in
case the encoder does not accept framerate=(fraction)0/1.
The acquired caps used for downstream negotiation are determined from
gst_v4l2_object_acquire_format(), which sets the GstVideoInfo::fps_n
and ::fps_d fields to 0.
To fix this, copy the frame rate from the sink side.

078560e70a v4l2: use GstV4l2Error in gst_v4l2_open() 
gst_v4l2_open() is called by gst_v4l2_device_provider_probe_device(),
where the GstV4l2Object is created without an associated GstElement.

If gst_v4l2_open() fails, it raises a bus message, but without an
element, a precondition check fails on
gst_element_message_full_with_details() generating a crash if running
with fatal-warnings debug mode.

GstV4l2Error is a helper to raise error bus messages when it is
appropiated. This patch changes the direct bus messages to this
helper, and the elements will actually send the error message.

ca61a76987 v4l2: Fix threading issues in orphaning mechanism 
The pool orphaning function was colling internal _stop() virtual function
implementation. This is not thread safe, as a private lock inside the buffer
pool is supposed to be held. Fix this by keeping delayed _stop() and orphaning
the GstV4L2Allocator instead (REQBUFS(0)).

Then, protect the orphaned boolean with the object lock for the case a buffer
is being released after we have orphaned the buffer. That would otherwise
cause a QBUF to happen while the queue is no longer owned by the buffer pool.
This boolean is otherwise used and set from the streaming lock, or after
threads have been stopped (final cleanup).

83f60aea54 v4l2bufferpool: Only resurrect the right amount of buffers 
On streamon, we need to resurrect (queue back) some buffers, as during
flushign seek we'd endup with an empty queued. We initially started with
resurrecting as many as we could without blocking, but that miss-behaved with
dynamic CREATE_BUFS, causing the pool to grow dramatically. This was limited
by the number of allocated buffers, but this still tried to resurrect too many
buffers for the first run, as activating the pool will queued buffers.

In this patch, we calculte the missing detal in the queue and only try and
resurrect that amount of buffers.
