ef9b7ef60a rtph265depay: only update the srcpad caps if something else than the codec_data changed
h264parse and gstrtph264depay do the same, let's keep the behaviour
consistent. As we now include the codec_data inside the stream, this causes
less caps renegotiation.

021333a9fc rtph265depay: Insert SPS/PPS NALs into the stream
rtph264depay does the same and this fixes decoding of some streams with 32
SPS (or 256 PPS). It is allowed to have SPS ID 0 to 31 (or PPS ID 0 to 255),
but the field in the codec_data for the number of SPS or PPS is only 5
(or 8) bit. As such, 32 SPS (or 256 PPS) are interpreted as 0 everywhere.

This looks like a mistake in the part of the spect about the codec_data.

fee3129d49 rtph265depay: implement process_rtp_packet() vfunc
For more optimised RTP packet handling: means we don't need to map the

already done.

9379933607 rtph265depay: prevent trying to get 0 bytes from adapter
This causes an assertion and would lead to getting a NULL instead
of a buffer. Without proper checking this would easily lead to a

8a6cc4ed27 codecparsers: h265: Fix the range of delta_chroma_log2_weight_denom
ChromaLog2WeightDenom = luma_log2_weight_denom + delta_chroma_log2_weight_denom

The value of ChromaLog2WeightDenom should be in the range of 0 to 7 and
the value luma_log2_weight_denom  should be also in the range of 0 to 7.
Which means , delta_chroma_log2_weight_denom can have values in the range
between -7 and 7.

80d77aa0a5 gltransformation: implement pivot point for rotation and scale
https://bugzilla.gnome.org/show_bug.cgi?id=744763

Add a pivot vector for setting the origin of rotations and scales.

With the pivot point the rotation and scale operations can have
different origins. This adds the ability to rotate around different points.
Currently the default (0, 0) pivot point is possible,
a rotation around the center, and zooming into and out of the center.

With an pivot point this is optional.
I defined the following image coordinates for the pivot point:

	 (-1,1) ------------------------- (1,1)
		|			|
		|			|
		|			|
		|	  (0,0)		|
		|			|
		|			|
		|			|
	(-1,-1) ------------------------- (1,-1)

Example:

	Rotate the video at the bottom left corner

	gst-launch-1.0 videotestsrc \
			! gltransformation \
		 		scale-x=0.5 \
				scale-y=0.5 \
				rotation-z=25.0 \
				pivot-x=-1.0 \
				pivot-y=-1.0 \
			! glimagesink

The pivot-z option defines the pivot point in 3D space.
This only affects rotation, since we have no Z data to scale.
With this option a video can be rotated around a point in 3D space.

Example:

	Rotate around point behind the video:

    	gst-launch-1.0 videotestsrc \
			! gltransformation \
				rotation-x=10.0 \
				pivot-z=-4.0 \
			! glimagesink

but if we're streaming send a TIME segment instead (which goes

3a765e0805 facedetect: fix profile loading check
Since the profile gchar depends on DEFAULT_FACE_PROFILE, it should never be

69becd734d h265parse: expose compatible profiles to downstream
Some video bitstreams report a too restrictive set of profiles. If a video
decoder was to strictly follow the indicated profile, it wouldn't support that
stream, whereas it could in theory and in practice. So we should relax the
profile restriction for allowing the decoder to get connected with parser.

93c10d3f0e dashdemux: Fix leak in gst_dash_demux_stream_update_fragment_info()
The gst_dash_demux_stream_update_fragment_info function could call
gst_dash_demux_stream_update_headers_info function twice. The
gst_dash_demux_stream_update_headers_info function will set header_uri and
index_uri to some newly allocated strings. The values set by the first call of
gst_dash_demux_stream_update_headers_info will leak when the function is
called for a second time.

The solution is to call gst_adaptive_demux_stream_fragment_clear before the
second call of gst_dash_demux_stream_update_headers_info
