--- Comment #5 from Jer Noble <jer.noble at apple.com> ---
Aha, this is a slightly different, but related, issue than the one in #135379. The CORS check fails because the scheme used for the <video> element ("blob://") does not match the one used for the page ("http://").  Additionally, nothing is painted to canvas because our MSE back-end does not currently support painting. We'll have to re-write the way decoding works to get access to the decoded frames before they're added to a AVSampleBufferDisplayLayer, in order to be able to paint efficiently. I raised this issue with Richard in the linked bug.
