Summary VideoEncoder does not call output callback on FullHD configuration

Created attachment 466864 [details] bug demonstration When encoding FullHD VideoFrame-s with avc1 VideoEncoder, the output callback is never executed even after encoder.flush() call. - This problem only exists on frames larger than ~912000 pixels (912x1000 or more, i.e. 1920x1080). - There is no error thrown during the code execution. - VideoEncoder.isConfigSupported reports that the config is supported. - Same config works on Chrome and produces encoded data. - However, the output callback is fired as expected on videos with lower resolution i.e. 1280x720. - Changing codec to vp8 or vp09.00.10.08 with FullHD res also works and produces encoded data. I tried to change various properties for `VideoEncoder.configure(...)` as well as `new VideoFrame(...)` but no luck. See attached safari-bug.html for demonstration.

actually the max working width/height is a tricky one to resolve: - 1280x720 works ok (921600 pixels) - 916x1000 does not work (916000 pixels)
