db382cbc3d videocrop: handle non raw caps features 
Currently, videocrop, only negotiates raw caps (system memory) because
it's the type of memory it can modify. Nonetheless, it's also possible
for the element to handle non-raw caps when only adding the crop meta
is possible, in other words, when downstream buffer pools expose the
crop API.

This patch enable non-raw caps negotiation. If downstream doesn't
expose crop API and negotiated caps are featured, the negotiation
fails.

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().

73fb107a85 rtspsrc: Fix accumulation of before-send signal return values 
Since glib 2.62, the accumulated return values in RUN_CLEANUP override the
accumulated return values in RUN_FIRST. Since:

1. We have a default handler that always returns TRUE, and
2. User handlers are only run in RUN_FIRST, and
3. Our accumulator just takes the latest return value

We were discarding the return value from the user handler and always
sending messages even if the user handler said not to. See
https://gitlab.gnome.org/GNOME/glib/-/issues/2352 for more details.

This signal does not need RUN_CLEANUP or RUN_FIRST, so just change it
to RUN_LAST so that it's emitted exactly once and accumulated once.

With this fix, this signal can now be used to intercept PAUSE when
going to GST_STATE_NULL so that the server does a TEARDOWN (if
necessary) and not a PAUSE, which will confuse other RTSP clients when
playing shared media.

242f3cae6d matroskademux: Fix extraction of multichannel WavPack 
The old code had a couple of issues that all lead to potential memory
safety bugs.

  - Use a constant for the Wavpack4Header size instead of using sizeof.
    It's written out into the data and not from the struct and who knows
    what special alignment/padding requirements some C compilers have.
  - gst_buffer_set_size() does not realloc the buffer when setting a
    bigger size than allocated, it only allows growing up to the maximum
    allocated size. Instead use a GstAdapter to collect all the blocks
    and take out everything at once in the end.
  - Check that enough data is actually available in the input and
    otherwise handle it an error in all cases instead of silently
    ignoring it.

Among other things this fixes out of bounds writes because the code
assumed gst_buffer_set_size() can grow the buffer and simply wrote after
the end of the buffer.

Thanks to Natalie Silvanovich for reporting.

6c461e90bc matroskademux: Initialize track context out parameter to NULL before parsing 
Various error return paths don't set it to NULL and callers are only
checking if the pointer is NULL. As it's allocated on the stack this
usually contains random stack memory, and more often than not the memory
of a previously parsed track.

This then causes all kinds of memory corruptions further down the line.

76d624b2df rtspsrc: Do not send PAUSE command when going to GST_STATE_NULL 
This usually doesn't matter, but it is disruptive when streaming from
a shared media since it will pause all other clients when any client
exits.

This new behaviour is opt-in and should be safe because you need to
set the NULL state on rtspsrc directly, instead of just on the
pipeline. See the updated documentation for an explanation.

Some cameras (e.g. HikVision DS-2CD2732F-IS) return "551 Option
not supported" when a command is sent that is not implemented
(e.g. PAUSE). Instead; it should return "501 Not Implemented".

This is wrong, as previously, the camera did announce support for PAUSE
in the OPTIONS.

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.

409ea3ac84 v4l2src: Move preferred resolution query before the probe

And use this framerate in our preference. Note that we also flush
the probed caps as it seems that the format enumeration may change
when a new source change event get triggered.
