Made some more changes to get data out to the video filter properly. Had
to change the SampleFormat enum order to get around the merge formats
issue. Like Stefano said, this requires changes to the filter graph
building code in order to work without the hack. I also need to use a
filter for splitting audio instead of having two outputs for aviz as below
as this crashes after a few buffers of audio data are pushed through the
data.

The ffplay test code for this is also attached.
