Ruffle does not support loading external video files yet. See #3801.

Also, the video file on this page uses the H.264 codec, which is unlikely to be supported by Ruffle anytime soon due to patent/licensing restrictions. Ruffle would need to use the browser's native video playback capabilities, which would be particularly difficult to implement.

This now needs NetConnection.client and mixed AVM support.

At least on desktop, this will be partially fixed by #14654.
For web, I have a WIP (but already functional) branch on top of that PR that delegates H.264 decoding to the browser through the WebCodecs API where supported.

For audio, the AAC-LC audio codec will also have to be wired up (probably/preferably from Symphonia).
