Speeding up video in Chrome browser

[Metaphore]

We have a custom interactive sign which spans several monitors and is implemented in an HTML 5 canvas.

We are attempting to add a video effect, namely a flock of birds flying through the foreground. We made an OGV file with the video and are displaying it with a transparent background over the sign. It works, but is very slow.

The video with transparency was made with ffmpeg.

Is there a better way to do this to make it faster?

Use H.264 instead of OGV, so you get hardware accelerated decode? OGV is mainly Ogg Theora, which is an ancient and sad codec.

And make sure you're running with a GPU and Chrome version that gives you H.264 accelerated decode.
