Because the lavf_container is sometimes called with only 2 arguments,
fate tests produce bash errors like this:

  tests/fate-run.sh: 299: test: =: unexpected operator

This commit fixes this.

Also normalize vector after rotation, it might be needed,
otherwise one can get NaNs.

roll/pitch can do exactly same thing.

Add option to change central point projection.

Due to the recent addition of Vulkan support to AMF, we require more
recent headers that include the new structures, which have been
available since AMF 1.4.9 released in September 2018.

Fixes Ticket #8125

Right now, the concat filter does not set the frame_rate value on any of
the out links. As a result, the default ffmpeg behaviour kicks in - to
copy the framerate from the first input to the outputs.

If a later input is higher framerate, this results in dropped frames; if
a later input is lower framerate it might cause judder.

This patch checks if all of the video inputs have the same framerate, and
if not it sets the out link to use '1/0' as the frame rate, the value
meaning "unknown/vfr".

A test is added to verify the VFR behaviour. The existing test for CFR
behaviour passes unchanged.
