Hi Julian. For your reference, the performance of ffmpeg on a certain h.264 video decode has regressed since 4.4.0.
See: http://ex.seabright.co.nz/helpers/benchcompare for the relative numbers. We're significantly better than 4.4.0 in the two other test videos, and better than 4.5.1 in all.
The video itself is here: http://ex.seabright.co.nz/misc/cbuild/live/cbuild/files/ffmpeg/03-src13_hrc7...
Clicking on this link caused firefox to try the render the entire movie as an insanely long web page, which made it run incredibly slowly such that it took me about 45 mins to find out why my browser was jammed even after restarting.
Just a warning to save others from some aggravation.
Wookey
