0fa43aaab4 h264parse: constrained-baseline is a subset of baseline
We get into this code path if the profile is already constrained-baseline and
downstream does not support constrained-baseline. So we should try baseline
and the other compatible profiles.

d8e681bb63 h264parse, h265parse: fix handling of downstream force-key-unit events
The parser handles the downstream force-key-unit event incorrectly,
it tries to parse it as an upstream force-key-unit event, does not
check the return value, and then uses uninitialized memory in
"all_headers" boolean variable.

5ebf1d477d mpegvideoparser: Handle non-hierarchical profiles again
This is a regression from since mpegvideoparser was switched to
use the codecparsing library.

The problem is that the high bit of the profile_and_level is used
to specify non-hierarchical profiles and levels. Unfortunately we
were discarding that information.

Expose that escape bit, and use it in the element

cf7056a312 videoparsers: h264: Disable passthorugh mode enabling
Enabling passthorugh mode is causing multiple issue:
For nal aligned multiresoluton streams, passthrough mode
make h264parse unable to advertise the new resoultions.
Also causing issues while parsing MVC streams which have two
separate layers (base-view and non-base-view).

This fix is only a temporary workaround.

For MVC, proper fixes needed in many places:
(handle prefix nal unit, handle non-base-view slice nal extension,
fix the picture_start detection for multi-layer-mvc streams etc)

b392a6e3b9 h264parse/h265parse: Fix negotiation crash
As it's recursive, gst_pad_get_allowed_caps() may also return
empty for anything incompatible downstream. EMPTY is not valid caps
value for gst_caps_fixate(). This lead to assertion and then crash.

value, and we could make the negotiation fails earlier.

This commit add an helper to convert a frame to frame-layer format and
use it to implement these two stream-format conversion:
- asf --> sequence-layer-frame-layer
- asf --> frame-layer

In simple/main profile, we basically have a raw frame, so building a
frame layer isn't too complicated. But in advanced profile, the first
frame-layer should contain sequence-header, entrypoint, and frame and
each keyframe should contain entrypoint, so we have to handle these
carefully.

It add the support of following stream-format conversion:
- bdu --> sequence-layer-bdu
- bdu-frame --> sequence-layer-bdu-frame
- frame-layer --> sequence-layer-frame-layer

For these conversion, the only requirements is to push a sequence-layer
buffer prior to data.

7d44a51bfe h264parse: fix collection of access units to preserve config headers.
Always use a GstAdapter when collecting access units (alignment="au")
in either byte-stream or avcC format. This is required to properly
preserve config headers like SPS and PPS when invalid or broken NAL
units are subsequently parsed.

More precisely, this fixes scenario like:
<SPS> <PPS> <invalid-NAL> <slice>

where we used to reset the output frame buffer when an invalid or
broken NAL is parsed, i.e. SPS and PPS NAL units were lost, thus
preventing the next slice unit to be decoded, should this also
represent any valid data.

34c2cfd4dd h264parse: improve conditions for skipping NAL units.
Carefully track cases when skipping broken or invalid NAL units is
necessary. In particular, always allow NAL units to be processed
and let that gst_h264_parse_process_nal() function decide on whether
the current NAL needs to be dropped or not.

This fixes parsing of streams with SEI NAL buffering_period() message
inserted between SPS and PPS, or SPS-Ext NAL following a traditional
SPS NAL unit, among other cases too.

Practical examples from the H.264 AVC conformance suite include
alphaconformanceG, CVSE2_Sony_B, CVSE3_Sony_H, CVSEFDFT3_Sony_E
when parsing in stream-format=byte-stream,alignment=au mode.

31d1c05871 h264parse: Add support for stream-format=avc3
When outputting in AVC3 stream format, the codec_data should not
contain any SPS or PPS, because they are embedded inside the stream.

In case of avc->bytestream h264parse will push the SPS and PPS from
codec_data downstream at the start of the stream, at intervals
controlled by "config-interval" and when there is a codec_data change.

In the case of avc3->bytstream h264parse detects that there is
already SPS/PPS in the stream and sets h264parse->push_codec to FALSE.
Therefore avc3->bytstream was already supported, except for the stream
type.

In the case of bystream->avc h264parse will generate codec_data caps
from the parsed SPS/PPS in the stream. However it does not remove these
SPS/PPS from the stream. bytestream->avc3 is the same as bytestream->avc
except that the codec_data must not have any SPS/PPS in it.

|--------------+-------------+-------------------|
|stream-format | SPS in-band | SPS in codec_data |
|--------------+-------------+-------------------|
| avc          | maybe       | always            |
|--------------+-------------+-------------------|
| avc3         | always      | never             |
|--------------+-------------+-------------------|

Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
structure for fragmented MP4 called "avc3". The principal difference
between AVC1 and AVC3 is the location of the codec initialisation
data (e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
(moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
first sample of every fragment.

b17676a1d5 h264parse: Do not trigger caps update if we only have PPS updates
Updating caps results in downstream elements potentially reconfiguring themselves

in those elements being reconfigured and handling garbage until the next keyframe.

Instead of this only send (potentially) new codec_data when we have *both* SPS and
PPS.

a9f46ed059 mpegvideoparse: only apply repeat count when set
When there is no extension header, the repeat_count variable is left to 0 and
then the duration on the output buffers is calculated wrongly. Because the
duration is used to interpolate output timestamps, the output timestamps are
also wrong, causing bad framerates.

7c6093357b videoparsers: Fix GstBaseParse::get_sink_caps() implementations
They should take the filter caps into account and always return
the template caps appended to the actual caps. Otherwise the
parsers stop to accept unparsed streams where upstream does not
know about width, height, etc.

Fixes bug #677401.

35a58df012 mpegvideoparse: Revert "fix crash"
This reverts commit 91210831ee672343a296f31357144359d5c2e768.

Such explicit reset should not be needed as it is arranged for by
the baseclass in unison with monitoring for a new frame by subclass.

As such it might wrongfully hide something else going on ...

Partially reverts commit 20669d461a while
trying to keep (some?) compilers happy.

IIRC, the purpose of GstByteWriter in the first place was (at least)
being able to dump data without having to fuss with memory expansion
and size issues ...

20669d461a Fix 'ignoring return value of function declared with const attribute'
This always happens with GstByteReader/Writer and friends when
not taking into account returned boolean of the _read/_write functions
(which is actually wrong).

Make use of the *_unchecked variant as much as possible, or take the
returned value into account.

c7216162e4 h264parse: remove _chain hack
As we can now rely upon being passed upstream delineated data in
::handle_frame(), the latter can also parse avc formatted data
without having to intercept baseparse's chain function.

While this evidently requires 2 separate parsing paths, each can
be streamlined accordingly.
