Before this, a failed test would keep failing because the output file
is not cleaned up and subsequent runs would refuse to overwrite it.

Uses the same mechanism as other codecs - conformance test files are
passed through the metadata filter (which, with no options, reads the
input and writes it back) and the output verified to match the input.

Can adjust the colour information.

This makes the trace output for arrays significantly nicer.

Make this clear in the documentation and add some asserts to ensure
that it is always true.

Helps with multi-channels audio. Otherwise use threads=1.

Create a buffer from the data instead and use the buffer destructor to free the
DeckLink frame. This avoids a memcpy of the frame data.

introduced.
