The SPS parsing functions take a parse_vui_param flag
to skip VUI parsing, but there's no indication in the output
SPS struct that the VUI was skipped.
The only caller that ever passed FALSE seems to be the
important gst_h264_parser_parse_nal() function, meaning - so the
cached SPS were always silently invalid. That needs changing
anyway, meaning noone ever passes FALSE.
I don't see any use for saving a few microseconds in
order to silently produce garbage, and since this is still
unstable API, let's remove the parse_vui_param.
The spec calls for pic_timing SEI to be absent unless
there's either a CpbDpbDelaysPresentFlag or
pic_struct_present_flag in the SPS VUI data. If
both those flags are missing, warn.
If parsing an SEI errors out, it might not consume
all bits, leaving extra unparsed data in the reader
that the outer loop then tries to parse as a new
appended SEI.
Skip all the bits if any are left over to avoid
'finding' extra garbage SEI in the parsing.
When parsing SEI that require an SPS, return
GST_H264_PARSER_BROKEN_LINK instead of a generic
parsing error to let callers distinguish
bitstream errors from (expected) missing packets
when resuming decode.
"High Throughput", "Multiview", "Scalable", "3D", "Screen Content Coding",
and "Scalable format range extensions" profiles can be supported
via h265parser APIs now.
The same timing_info will be present at vps or vui.
When the timeing_info is present in the VPS, vui_timing_info
, when present, shall be equal to vps_timing_info, and when
not present, is inferred to be equal to vps_timing_info.
It's almost a fork of glwindow_win32 implementation.
To build on Windows, Vulkan SDK (at https://vulkan.lunarg.com/sdk/home)
and VK_SDK_PATH environment are required. Note that VK_SDK_PATH environment
setting is a part of the SDK installation.
Limitations:
- No transport changes at all (ICE, DTLS)
- Codec changes are untested and probably don't work
- Stream removal doesn't remove transports (i.e. non-bundled transports
will stay around until webrtcbin is shutdown)
- Unified Plan SDP only. No Plan-B support.
Having the opencv feature enabled would lead to the opencv3 dependency
being required which failed with only opencv4 being available.
Instead don't require anything and error out at the end if the feature was enabled
but no dependency was found.
Expose SEI data in the H.264 bitstream parser API and
extract closed captions and other things that are not
specified in the H.264 spec itself in the videoparser.

This is the equivalent of iceTransportPolicy in the RTCConfiguration
dictionary.
Only two values are implemented:
* all: default behaviour
* relay: only gather relay candidates
The third member of the iceTransportPolicy enum, "public", is
obsolete.
* Add FIXME for future correction of HRDParames parsing.
Spec. defines that the number of HRDParames could be up to
"vps_num_layer_sets_minus1 + 1" (i.e., 1024).
* Add parsing vps_base_layer_{internal,available}_flag.
* Fix possible invalid vps_extension parsing.
Fixes#798
Otherwise setting an URI after creation will already set the state
to READY/buffering and disallow setting the configuration.

For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.
This fixes linker warnings on Windows when building with MSVC.
The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.
What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.
While we're at it, add new GST_API_EXPORT in config.h and use
that for GST_*_API decorators instead of GST_EXPORT.
The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.
We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.
The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h
Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.
This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

When the position query fails the returned value shall remain -1 instead of 0 to
avoid confusion on application side between error and beginning of media.

Move the errant piece of dtlssrtpenc state change
management from dtlstransport in the Webrtc libs,
into the transportsendbin that does the rest of
the element management so it's all in one place.
It is completely legal to have packets with zero sizes.
Zero-sized packet indicates header with only Start Code.
One eg: is user data packet. The patch allows having
GstMpegVideoPacket with zero sizes.

If connection-speed property is in use, this value should be used as the
current download rate since subclasses might read it to figure out
which playlist variant they will use.

Regardless of LIVE or VOD, "a manifest has next period but
currently EOSed" state is meaning that it's time to advance period.
Previous behavior of adpativedemux, however, was able to period
advancing only for VOD case, since the adaptivedemux tried to
update and wait new manifest without respecting existence of the next period.

This moves all the conversion related code to a single place, allows
less code-duplication inside compositor and makes the glmixer code less
awkward. It's also the same pattern as used by GstAudioAggregator.
This is only used for caching reasons and should never actually be in
the public API. If this is ever a bottleneck later, caching around a
class private struct could be implemented.
The aggregated_frame is now called prepared_frame and passed to the
prepare_frame and cleanup_frame virtual methods directly. For the
currently queued buffer there is a method on the video aggregator pad
now.
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
