Supporting HEVC/H.265 videos in Electron

Chrome/Electron don't normally support H.265 videos. I want the user to be able to play .mov files recorded by Apple devices in my app. How can I do this?

Possible approaches:

1. Use ffmpeg to transcode to H.264 in real-time, which will be resource intensive (not ideal)
2. Use WebAssembly to render the video in a <canvas> tag (not ideal)
3. Fork and manually add H.265 codec support to Chrome/Electron (overkill)
4. Use a native module that renders the video in a <canvas> or BrowserView
