9b2e1f9f36 rtph265depay: Don't assume that get_current_caps() returns non-NULL caps after has_current_caps()
Remove calls to gst_pad_has_current_caps() which then go on to call
gst_pad_get_current_caps() as the caps can go to NULL in between. Instead just
use gst_pad_get_current_caps() and check for NULL.

f2f31ec50f rtp: h264/h265: avoid duplication of read_golomb()
There is no need to have two identical implementations of the read_golomb
function.

139108c83a gstrtph265depay: keep consistency with rtph264depay
Use gst_rtp_drop_meta() and the same function prototype for
gst_rtp_copy_meta() to keep consistency with the RTP elements in

403ac009fa rtph265depay: fix termination of access unit
Only consider the access unit complete when the next-occurring VCL NAL unit
has the first bit after its NAL unit header equal to 1.

983e30f658 rtph265depay: fix unneeded sub-buffer creation
We create a sub-buffer just to copy over its metas and then throw it
away immediately, just use the original input buffer directly.

698e5bbfb5 rtph265depay: make sure we call handle_nal for each NAL
Call handle_nal for each NAL in the STAP-A RTP packet. This makes sure
we correctly extract the SPS and PPS.

f1e2849438 rtph265depay: copy metadata in the depayloader, but only the relevant ones
The payloader didn't copy anything so far, the depayloader copied every
possible meta. Let's make it consistent and just copy all metas without
tags or with only the video tag.

18b628824b 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.

d10b6f1e3a 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.

0bfa97b047 rtph265depay: implement process_rtp_packet() vfunc
For more optimised RTP packet handling: means we don't need to map the
input buffer again but can just re-use the mapping the base class has
already done.

470c8b3720 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
segfault.

59fea44503 rtp: fix nal unit type check
After further investigation the previous commit is wrong. The code intended to
check if the type is 39 or the ranges 41-44 and 48-55. Just like gsth265parse.c
does. Type 40 would not be complete.

d215b18a20 rtp: fix dead code and check for impossible values
nal_type is the index for a GstH265NalUnitType enum. There are two types of dead
code here:
First, after checking if nal_type is >= 39 there are two OR conditionals that
check if the value is in ranges higher than that number, so if nal_type >= 39
falls in the True branch those other conditions aren't checked and if it falls
in the False branch and they are checked, they will always also be False. They
are redundant.
Second, the enum has a range of 0 to 40. So the checks for ranges higher than 41
should never be True.
Removing this redundant checks.
