1d38728d05 h264decoder: Perform low-latency outputting only for live pipeline
Frequent outputting might drop throughput-wise performance.

00ad871628 h264decoder: Output decoded pictures as soon as possible
In case of IDR, any previously decoded pictures must be drained
before the IDR and POC of IDR should be zero. So we can output
IDR immediately. Also, when POC of current picture is expected to be
the next output POC, decoder can output the picture as well
without waiting.

90f374dd0c openh264: memcmp return value 0 means match
Commit e2aa76db79 introduced version
check guard for OpenH264 binary. There was a boolean error in
memcmp so matching OpenH264 was erroneously rejected.
Fixes #1278

4d585c64d1 nvcodec: Add suppport for environment based primary h264 decoder implementation
Introduce GST_USE_NV_STATELESS_CODEC environment to allow user to select
primary nvidia decoder implementation. In case the environment
GST_USE_NV_STATELESS_CODEC=h264 was set, old nvidia h264 decoder element
will not be registered. Instead, both nvh264dec and nvh264sldec
factory name will create gstcodecs based new nvidia h264 decoder element.

9c21923f04 nvcodec: Add H264 stateless codec implementation
Introduce GstH264Decoder based Nvidia H.264 decoder element.
Similar the element factory name of to v4l2 stateless codec,
this element can be configured with factory name "gstnvh264sldec".
Note that "sl" in the name stands for "stateless"

For now, existing nvh264dec covers more profile and formats
(e.g., interlaced stream) than this implementation.
However, this implementation allows us to control lower level
parameters such as decoded picture buffer management and therefore
we can get a chance to improve performance in terms of latency.

62d1a3a143 cccombiner: don't drop buffers on video timestamp discontinuities
If we receive video buffers with non-perfect timestamps, the
caption buffers' timestamps might fall in the interval between
the end of one video buffer and the start of the next one.

Make our criteria for dropping that the caption buffer has
a timestamp older than the end of the previous video buffer,
not older than the start of the new one, unless of course
this is the first video buffer.

ac850fd25d v4l2slh264dec: Support avc and avc3 formats

0d637c14c5 h264/h265parse: Fix handling of very last frame
Baseparse will never call us back on draining, so going into more: label will
cause the current frame to be discarded. So if we have a complete NAL, but not
a complete AU, make sure to terminate the frame properly.

This is a gression introduce by commit e88d848070 and
a194a87b26.

63940feaaf kmssink: Save last metadata at the same time as the last buffer
The render width/height and the vinfo was only saved upon renegotiation. This
fixes the problem by saving this metadata at the same time the buffer is
saved. The saved copy of this is needed for expose() and drain() virtual functions.
This fixes various assertion that happens on drain query.

e88d848070 h265parse: Don't wait for next NAL if input is aligned
Waiting for the next NAL increases the latency. If alignment=nal/au
has been negotiated, assumes the the buffer contains a complete
NAL and don't expect a second start-code. This way, nal -> nal,
au -> au and au -> nal no longer introduce latency.

As a side effect, the collect_pad() function was not able to poke at the
following NAL. This call is now moved before processing the NAL, so
it's looking at the current NAL before it's ingested into the parser
state in order to dermin if the end of an AU has been reached. The AUD
injection state as been adapted to support this.

This change will break pipelines if alignment=nal is used without respecting the
alignment. Effectively, the parser will no longer fix the broken aligment
which will result in parser error and the termination of the pipeline. Such
issue existed in tsdemux element and might exist in any forks of that code.
