898b436219 h263parse: Fix PSC matching
We were off by one byte in the matching

It should be (using 24 bit matching):

   * mask (bin) : 1111 1111 1111 1111 1111 1100
   * mask (hex) :    f    f    f    f    f    c
   * match      :    0    0    0    0    8    0

6adf3c2499 h263parse: fix custom picture format (CPFMT) parsing
In the H263 spec, CPFMT is present only if the use of a custom
picture format is signalled in PLUSEPTYPE and UFEP is "001",
so we need to check params->format and only if the value is
6 (custom source format) the CPFMT should be read, otherwise
it's not present and wrong data will be parsed.

When reading the CPFMT, the width and height were not
calculated correctly (wrong bitmask).

14f6fcdbd8 h264parse: reset the parser information when caps changes
This prevents it from going into passthrough after receiving 2
byte-stream caps (different ones) as it would keep the have_pps and
have_sps set to true and would just go into passthrough without
updating its caps.

This patch makes it reset its stream information to restart properly
when new caps are received.

Some video bitstreams report a too restrictive set of profiles. If a video
decoder was to strictly follow the indicated profile, it wouldn't support that

59e7f0597d pngparse: improve parsing of the image
Everytime a buffer is being provided from baseparse, we are parsing all the data from the beginning.
But since we would have already parsed some of the data in the previous iterations,
it doesnt make much sense to keep parsing the same everytime.

025f8b9129 vc1parse: implement asf to *-frame-layer stream-format
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.

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.

67df207280 codecparsers: h264: add support for Recovery Point SEI message.
The recovery point SEI message helps a decoder in determining if the
decoding process would produce acceptable pictures for display after
the decoder initiates random access or after the encoder indicates
a broken link in the coded video sequence.

This is not used in the h264parse element, but it could help debugging.

d9d4a91c62 h265parse: fix hvcC size check
In ISO/IEC 14496-15, the minimum size of a HEVCDecoderConfigurationRecord
(i.e., the contents of a hvcC box) is 23 bytes. However, the code in h265parse
checks that the size of this data is not less than 28 bytes, and it refuses to
accept caps if the check fails. The result is that standards-conformant streams
that don't carry any parameter sets in their hvcC boxes won't play.

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.

Right now decodebin will concider the pad template caps as fixed and if a decoder

gst_caps_is_subset fails as those fields are missing from the pad template caps.

da89903f81 h264parse: disable optimized packetized processing for reverse playback
... as baseparse then provides whole chunks of data (as it should) at once
to be parsed, and so the assumptions used to optimize are no longer valid.

Fixes #667560.

94ae4ca833 h264parse: do wait for a keyframe when handling force key unit events
Although some decoders can start decoding with just PPS and SPS and waiting for
a keyframe is bad when the keyframe interval is large, gst-ffmpeg does need a
keyframe to start decoding.
