the old manner does not consider the profile idc. The profile idc should
play an more important role in recognizing the profile than the other
information. And there is no need to mix profiles of different extensions
together to find the closest profile when the bits stream is not standard,
different extensions support different features and should not be mixed.
The correct way should be recognize the extension category by profile idc
firstly, and then find the closest profile.

GstH265FormatRangeExtensionProfile declares the common bits used
for not only format range extensions profiles, but also for several
different h265 extension profiles, such as high throughput, screen
content coding extensions, etc. And So the old name is not proper.

If there are two elements and threads attempting to query each other for
an OpenGL context. The locking may result in a deadlock.
We need to unlock each element's context_lock when querying another
element for the OpenGL context in order to allow any other element to
take the lock when the other element is querying for an OpenGL context.

Downstream may provide extra things when we ask it for caps that we may
need to remove.
Fixes the following pipeline warning:
gltestsrc ! glvideomixerelement ! glimagesinkelement
** (gst-launch-1.0:908581): WARNING **: 13:53:28.518: glvideomixer0: update_src_caps returned caps which are not a real subset of the filter caps
Include the Program Stream Map packet type 0xBC in the
set of packets we treat as PES. This fixes typefinding
on MPEG-PS streams with PSM, where the PSM would previously
be considered a loss-of-sync and cause the typefind
to require more data.
Fix the check for whether the element is operating in ARGB mode. It
was incorrectly checking if the output format has an alpha channel,
which is true for both ARGB and AYUV, leading to the element
incorrectly outputting ARGB values into AYUV caps.
The string "\"OTIO_SCHEMA\":" is 14 characters and not 15. Checking for
15 characters would also check for the final '\0', which does not exist
in any otio file as the string is the key of a JSON map.
memcmp() returns 0 (aka FALSE) on match and a difference otherwise.
Previously the typefinder was matching on anything but otio files that
happened to have some curly braces in the beginning of the file.
Fixes a false positive with a MOV file.
When receiving an instant-rate-change event, store the updated
seek flags and replace the flags in any input segments with them
to allow for instant switching between trickmodes and not.

It's possible that a buffer might be within the segment proper,
but not within the "valid" part we're playing, which is only
things after the 'offset' part of the segment. In that case,
the running-times of the buffer-start and buffer-stop will be
GST_CLOCK_TIME_NONE, and we'd better not schedule playback that
far in the future.
This commit modifies GstVideoMasteringDisplayInfo and GstVideoContentLightLevel
structs so that each value is to be more like hdr_metadata_infoframe struct
of linux drm header and DXGI_HDR_METADATA_HDR10 struct of Windows.
So each value is no more fraction but normalized one as per CTA 861.G spec.
Also the unit of each value will be consistent with H.264, H.265
specifications, hdr_metadata_infoframe struct for linux and
DXGI_HDR_METADATA_HDR10 struct for Windows.

Because the color value is stored in MSB, so we can reuse the
Y210 code for P012_LE / P012_BE
Sample pipeline:
gst-launch-1.0 videotestsrc ! video/x-raw,format=Y212_LE ! glimagesink
This can be used to have compositor display either the background
or a stream on a lower zorder after a live input stream freezes
for a certain amount of time, for example because of network
issues.
