19382f1e91 openh264: Conditionally support the main and high profiles 
openh264 added main/high profile support upstream after the 1.8.0
release, so detect a version higher than that and support main/high
stream input

40de7e5b98 openh264: Use DecodeFrameNoDelay() API instead of DecodeFrame2 
Replace legacy usage of DecodeFrame2 API in favour of the
recommended DecodeFrameNoDelay()

This fixes problems with DecodeFrame2() not (currently) returning
all frames in main/high streams with B-frames, and reduces latency -
previously openh264 would not return a decoded frame until the next
call to DecodeFrame2(). DecodeFrameNoDelay() returns them immediately.

d4594c5c75 openh264dec: Handle B frame decoding 
Support out-of-order decoding in OpenH264 by tracking
our internal frame reference in the OpenH264 timestamp
field.

Drain any pending frames at EOS.

984b150e65 openh264dec: Fix up EOS handling 
If the last frame(s) produce errors, then we need to drop them
or else we spin forever failing to decode a frame and thinking
it'll get better if we wait for more data that's never coming.

d1eb5f727c openh264dec: Drop current frame if passing it to the decoder caused an error 
Otherwise we will get it again later for output, however this frame will
never actually be output so we will shift timestamps.

This is especially bad if we're handling a live stream where the first
frames are not keyframes. We would output the keyframe with the
timestamp of the first frame, and everything would be too late when
arriving in the sink.

329f0ccba1 Revert "openh264: fix to work with released versions and master of upstream" 
This reverts commit 15394aa705.

The latest release (v1.1) does not have pkg-config support
yet, so this plugin won't be built with the latest release.
Cerbero uses the latest release, so this makes cerbero
builds fail, which expect the plugin to be built.

We can re-commit this once there's a release that includes
pkg-config support.

and declare this also on the srcpad caps.

With baseline profile there are no B-frames or frame reordering.

0e15f47bdf openh264dec: Try to handle frame reordering 
As openh264 has no way to attach any IDs to input frames that we then get on
the output frames, we have to assume that the input has valid PTS. We just
take the frame with the oldest PTS, and if there is no PTS information we take
the one with the oldest DTS.
