VideoTextures on Safari and seeking issue

[dustinkerstein]

@mrdoob Since we're talking about all this video stuff, I have a somewhat related question / possible bug, though it likely only affects my particularly use case. In this example I try to set the currentTime to some frame before showing the texture. I don't ever want to show frame 0. In the above example, it should immediately load to the frame that appears half cut-off. This works fine in Chrome and Firefox, but on iOS Safari it somehow forces me to render frame 0. Try tapping the screen and it will force a needsUpdate and then show the new frame, but no matter how long those setTimeouts are, it always will show frame 0 initially. On Desktop Safari, I see the same behavior, but it's compounded by the flashing black issue. Any ideas on why this happens, or how to avoid it?

Thanks,
Dustin

Sorry, but better to use the forum for questions like this.

Fair enough :) Just thought it could somehow be related to some of the existing Safari issues we were discussing (ie. the black frame flashing).

Right. We should report these to Apple though. It's dangerous!

FYI - I posted over on the Three.js Discourse - https://discourse.threejs.org/t/video-texture-updates-sometimes-showing-previous-frame/2247 - and also put together a simple color coded JSFiddle example that highlights this Safari issue - https://jsfiddle.net/rj7L0rsa/
