Current Behavior

When I use the rotate function on a video, it only rotates the video once halfway through the video. All the other functions work.

Expected Behavior

I expected it to apply evenly throughout the entire video.

Steps To Reproduce

This is the command sequence I used:

node wackywebm.js rotate -a 45 -o <output path> <input video path>

you can see in the output that it is applying the rotation to half the frames at a time, rather than one by one as with the other tools.

Using minimum w/h 1px.
