[WebGL] VideoPlayer is not rendered in WebGL builds when the video is loaded via URL

WebGL

Oct 01, 2019

How to reproduce:
1. Open the attached project ("case_1188316-Webgl_bug.zip")
2. Open the repro scene ("SampleScene")
3. Switch build target to WebGL
4. Enter Play Mode and notice that the Video starts playing
5. Exit Play Mode
6. Make a WebGL build and run it

Expected results: Video starts playing in the build the same way as in the Editor
Actual results: VideoPlayer window stays completely black, warnings are thrown in the browser's console ("Error: WebGL warning: texSubImage2D: Source must not be null.")

Couldn't test with 2019.2.0a7, 2019.2.0a8 ("RuntimeError: memory access out of bound" error is thrown on WebGL builds)

Reproduced with browsers: Chrome (77.0.3865.90), Firefox (69.0.2) Opera (63.0.3368.107)
Not reproduced in Edge (44.18362.329.0)

The only way I was able to play the unity webgl video on an iPhone was using this browser: https://apps. apple. com/us/app/webxr-viewer/id1295998056 although I know this does not fix the real problem.

Still not working on 2020.2.0b11. Tried both render texture, material rendering, far and near plane rendering.
