Looking at the provided test, the encoding part seems fine, it encodes around 150 video frames.
Looking at WebCodecs input, it seems most VideoFrames have the same content as the previous ones.
The issue might be in the generation of the VideoFrames from canvas, or maybe the canvas drawing.

@Ashley, I have difficulties debugging your canvas -> VideoFrame code.
It might help if you could you take a look at your canvas -> VideoFrame code path, maybe isolate what you are doing in a separate page that I could play with.
