e7f8c62d42 openh264enc: Remove broken byte-stream to avc conversion and just output byte-stream as generated by the encoder 
The byte-stream to avc conversion did not consider NAL sizes bigger than 2^16,
multiple layers, multiple NALs per layer, and various other things. This
caused corrupted streams in higher bitrates and other circumstances.

Let's just forward byte-stream as generated by the encoder and let h264parse
handle conversion to avc if needed. That way we only have to keep around one
version of the conversion and don't have to fix it in multiple places.

9617a371ca openh264: remove unnecessary instance private structures 
Element instance structures are not public API, so no need
for the extra indirection to hide the data.

5109d9930c openh264dec: Uninitializing the decoder can't fail and will always return 0 == cmResultSuccess 
... but when we cast cmResultSuccess to a gboolean it will be FALSE, and make
GstVideoDecoder::stop() fail for no reason.

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.

354fa3f2c9 openh264enc: Add new enable-frame-skip property and disable it by default 
Otherwise e.g. videotestsrc ! openh264enc ! ... will drop every second frame
because otherwise the target bitrate can't be reached without loosing too
much quality.

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.
