This patch set adds a native On2 VP4 decoder to FFmpeg, and completes the set of Duck/On2/Google authored codecs.
VP4 is similar to VP3, adding new tables and some new tricks. Loop filtering is performed between the motion compensation and apply idct steps. For all my test streams, output is bit identical to the reference decoder. I have tested it on x86 and arm, but not done fuzzing to find hangs. Suggetions how to improve it are most welcome.
