In practice most videos are larger than most gifs. Yes, there are exceptions, and yes, there are other features that we could add to further reduce bandwidth usage, but we shouldn't let perfect be the enemy of good. Especially given that autoplay was explicitly added in order for UAs to implement policies such as the ones discussed here. It seems silly of us not to take advantage of that. If gfycat absolutely wants to autoplay their videos, they can still use the .play() API. That's what the spec says to do. That said, if you have ideas for how we can do even better, definitely speak up. I'd be happy to stop downloading animated gifs over a certain size over mobile connections if we can have some UI which lets the user resume the download. / Jonas _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
