Thanks Sebastian. Do you have any suggestions as to how I may save my video stream to disk?

I presume I'd have the same problem if I used ogg theora instead of vp8 webm ?

I have a tee element after the webmmux element and I add a branch (queue ! filesink) dynamically. It is saving data, but it appears to be missing the webm header information and the resulting file is not playing.

Yes, it's in the caps in the "streamheader" field after webmmux.
multisocketsink and other elements are using that to allow new clients
to connect at a later time, but filesink is not going to do anything
with it right now.
