I couldn't find any info on either Theora codec or the plug-in, but does it support alpha-channel?

I looked for that too, and didn't find any info saying alpha channel is supported.
If you want to make some kind of mask you should use another ogg as a mask and change the shader to use it.

theora codec doesn't support alpha AFAIK. you could modify the shader as bartiss proposed to achieve some custom effect.

update on this, I've managed to "fake" alpha in a video, by adding a grayscale channel on the left side of the video frame and then manually merging it into a texture of half width upon decoding
