I don't believe so. There were two issues that could cause the assertion, one is we have a pending decoding in progress (1), and the other an initialisation in progress (2). We've definitely fixed (1). that leaves (2) I'll add some checks to check if that's the case.

Comment on attachment 8875292 [details] Bug 1370805: P3. Use whichever extradata is available when constructing the decoder. https://reviewboard.mozilla.org/r/146694/#review151082

Let current operation completes before continuing. https://reviewboard.mozilla.org/r/146692/#review151078 > We should also reject mDecodePromise here, right? the promise has already been rejected in H264converter::Flush() Decode can't be called before the flusb promise has been resolved. i could add an assertion in Decode that the flushpromise is empty too
