This must have happened sometime during the last two weeks. Canvas drawImage reliably (tested on clean profile) fails with an exception (NS_ERROR_DOM_SECURITY_ERR) if the video has finished loading. Everything works fine while it does.

Reproducible: Always

Steps to Reproduce:
1. Go to linked url
2. Quickly hit play while the video is still loading
3. Wait for it to finish loading
4. hit play again.
Actual Results:  
The canvas below the video is only updated (it should show the same image as above with anaglyph depth encoding) while the video is still loading. Afterwards you get a whole lot of errors in the console.

Expected Results:  
It should work no matter what the loading state of the video is.

roc, I think there was an issue related to channels in the media cache triggering security problems?  I think this is a trunk build he's using so that might be an issue.
Version: unspecified → Trunk
It is a trunk built and after testing with 1.9.1 it seems like a trunk-only issue.
