VideoTexture position animation is inconsistent

[mauro1855]

Hi Lightning SDK team,

I created recently a little project to see how I could create "video thumbnails" that start playing when I focus the element - it involved punching a hole in the canvas (with the HoleShader) and changing the position and size of the VideoPlayer (with VideoPlayer.position() and VideoPlayer.size() methods)

But I found that the VideoPlayer.position() behaviour is not consistent when textureMode is turned on or off.

• If textureMode is turned off, the style is updated and the video player tag "jumps" to the location.
• If textureMode is turned on, the texture is "smoothed" into the location, thus causing a delay until it actually reaches there. This means that, with the a hole punched in the canvas, you can see the video texture sliding into place.

I find this behaviour difference between texture and non-texture mode to be inconsistent, and provides an unpredictable and uncontrollable experience to developers. Not only with the VideoPlayer.position() method, but with the .size(), .show() and .hide() methods as well - the VideoTexture animates / smooths all of them, while the video tag is directly assigned the CSS style which takes effect immediately without animation. Besides being inconsistent, it is rather opinionated as well; it assumes the developer wants the smooth effect, while it might not be the case.

You can find the relevant code here and here.

Would you consider a PR to remove the smoothness out of the video texture?

Best regards, Mauro

Hi @mauro1855, thanks for your report.

Starting v5.0.0 the VideoPlayer plugin is no longer part of the Lightning-SDK. It’s been moved to the Metrological-SDK.

I’m not able to move issues between organizations, so I would suggest to open this issue as a new ticket over here.
