I tested the demo at https://moq.dev/publish/ and it's buttery as hell. Very impressive. Thanks for the great technology!

Watching the Big Buck Bunny demo at https://moq.dev/watch/?name=bbb on my mobile phone leaves a lot of horizontal black lines. (Strangely, it is OK on my PC despite using the same Wi-Fi network.) Is it due to buffer size? Can I increase it client-side, or should it be done server-side?

Also, thanks for not missing South Kora in your "global" CDN map!

Is it Chrome only? On Android Firefox it just says no browser support :(

Same here

Horizontal black lines? Dunno what that could be about, we render to a <canvas> element which is resized to match the source video and then resized again to match the window with CSS.

What’s that like for performance and power usage? I understand normal videos can generally be entirely hardware-accelerated so that the video doesn’t even touch the CPU, and are passed straight through to the compositor. I’m guessing with this you’re stuck with only accelerating individual frames, and there’ll be more back and forth so that resource usage will probably be a fair bit higher?

An interesting and unpleasant side-effect of rendering to canvas: it bypasses video autoplay blocking.

Doesn't show up on screen capture, but there's random rolling quickly flickering lines on my phone, kinda like from analog distortion on old tvs

I have got same issue with the black lines

The page mentions a lot of Rust code and WASM. Maybe your phone's CPU cannot run WASM fast enough?

My Samsung S20 shows no black lines.

My Samsung S24 Ultra shows black lines too, on Chrome and Samsung Internet.

Chrome on my oneplus ten, I get flickering black lines routinely. The fact they're going from somewhere along the top, down towards the right makes me wonder if it's a refresh artifact maybe? It's sort of like the rolling shutter effect

On a mac book air m4 with a 600mbps connection, it's instantaneous and amazing.

with this pc spec and internet speed, I expect its "normal"

[stronglikedan]

I don't get the black lines on Android/Chrome but it doesn't respect my aspect ratio when I go full screen. Instead of adding black bars to the sides, it excludes the top and bottom of the video completely.

I am bad at CSS.

Holy shit that starts streaming fast! like WTF
