Looping in movieTexture does not cache the video #1269

Open parthranawat opened 1 year ago

parthranawat commented 1 year ago

The video is downloaded for every loop over the network when setting the loop attribute as "true" in the MovieTexture tag. I am unsure why it is not caching the video and if it is a browser/video-specific issue.

Browser- Chrome (Version 112.0.5615.49 (Official Build) (arm64)) OS- MacOS Video- .mp4 file (128mb in size) [LINK]

I tried https://metagrid1.sv.vt.edu/~parthranawat/Nazila_Class_23/ but could not get Scene 2 Day to start to play.

For Scene 1 Day it did not reproduce with loop=true on my system (latest Chrome, Win10).

Did you try to enable cache in devtools ?

I think all what loop=true does is to call video.play() after the video ended. There is no explicit fetching from the network.

Here is a related question:

128MB may be too large somehow.

We would need a simple scene which consistently shows the behavior.
