Faster encoding speed #554

I feel that generating webm videos takes quite too long, compared to other h264 
encoders.

Let's say, for example I want to convert 900 images into a video with this 
command:

avconv -f image2 -r 15 -i /tmp/test/input/%d.jpg -an -b:v 256k -r 25 -y 
/tmp/test/output/video.webm -loglevel info -c:v libvpx -deadline rt

It takes about 3 minutes to encode! With libx264 it's only 20 seconds. That's a 
difference of 9 times.

Discussed on mailing list - turned out to be due to parameter ordering.
