Instead, store them in the context and compute on each parameter change.

We do not allow the frame parameters to change during encoding, so there
is no need to do this for each frame.

Intel i263 codec has special 8-byte dummy frames that should not be decoded,
so do not even attempt to decode them and skip them instead.

Only its size is actually used. Silence a clang warning.

Issue present in Avigilon IP cameras.

Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

It will be useful in the following commits.

Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.

Fall back to 1 (which is what is used for most cases anyway) when the
framerate is not set.

It has not been properly maintained for years and there is little hope
of that changing in the future.
It appears simpler to write a new replacement from scratch than
unbreaking it.

The new name more accurately describes what the file is about.

This is no longer needed since the version bump.

It is also not final yet, so require -strict experimental.

Requires a bump to version 17.

It obvously needs to be above the include statement.

The files are only ever compiled if that condition is true.
