On the RPI, three different /dev/video devices exist (decoder, scaler, encoder).
When probing the devices in order, the originally requested pix fmt
would be mutated causing the wrong one to be chosen when a matching
device was finally found.

In rare circumstances, if the codec is not configured with the
proper parameters the input buffers can be allocated with a size
that's too small to hold an individual packet. Since MediaCodec
expects exactly one incoming buffer with a given PTS, it is not
valid to split data for a given PTS across two input buffers.
See https://developer.android.com/reference/android/media/MediaCodec#data-processing:
> Do not submit multiple input buffers with the same timestamp

When duplicating frames we need to schedule for activation again, otherwise frames can build up in the inlink fifo.

some bitstream have trailing junk, despite being valid webp data.
In case of apparent error, abort the loop and let *got_frame
decide whether this is an error or not.
fixes trac #8107 (/#7612)
Another possibility would be turning the loop into:
while (!*got_frame) {...}

The loop may mutate the input buffer, so re-fetch it to ensure
the current one is always used.

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

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.
