Decode AV1 video (WebM) using the <canvas> tag

Same AV1/WebM source as the video tag version demo above, but rendered directly to a <canvas> instead of being re-encoded to MP4 — no encoder filter needed, since the decoded frames are drawn straight to the canvas.

Code snippet

<canvas is="universal-canvas_1" data-url="CityHall_640x360.webm" using="solver_1"
     with="libaom_1;webmdmx_1"> </canvas>
