I have some more time available to allocate to testing and review of experimental ffv1 version 3 and wanted to check in on the current state of the evaluations. I see that Peter's test scripts detected some hard to find errors and that the git commit log has been active for ffv1. I wanted to check in to determine where the priorities still exist for testing and review.

Peter's test scripts provide a lot of stats on file size and encoding speed for different combinations of coder, context, gop size, slicecrc use, and other options. I could send this data through gnuplot to provide clearer summaries of the hundreds of lines of test results, especially gop size, slice count, and compression rates.
