Description

The conformance tests use video.currentTime > 0 before they upload textures. We've found this is voodoo programming and doesn't actually work, at least in Chrome. You might need to slow the network traffic down to see that it doesn't actually work.

Doesn't there need to be an official correct and tested way to pass an HTMLVIdeoElement to texImage2D and not generate an error? Even the texture being blank is better than spurious errors IMO.

Research direction

Start with the conformance tests that set video.currentTime > 0 before calling texImage2D or texSubImage2D, and reproduce the behavior with slowed network traffic. Define and test the official HTMLVideoElement usage in the spec so texture uploads do not produce spurious errors.
