Probably won't have time to analyse any time soon, but I suspect that the refcounted buffer stuff completely broke direct rendering, and it might not even be fixable.
You can just disable dr and live with FFmpeg getting slower and slower due to more and more optimizations being removed/broken (though in most cases new asm instructions and multithreading making up for it - doesn't help users of older or weaker hardware though)
