    So It looks like issue is resolved. I'm about to check the new version. Anyone try it out yet?

    @SIMBA-MUPFUNYA Given their recent release cycle history:
    https://unity3d.com/pt/get-unity/download/archive
    Probably in 1 to 1.5 weeks

    @Bluesheep They say the fix will be included in 2020.1.0b9 and currently only 2020.1.0b9 is available, so you will have to wait a couple of days.

    This issue is absolutely infuriating. I even downloaded the Beta 2020.1 bc it says they've fixed it, but it doesnt run there either! Beta isn't even equipped to run in a live server, and even in the localhost build the videos dont work.

    For my project it is imperative that I am able to use video in my WebGL build, and the fact that I see this issue has existed for years, across many versions of Unity is insane. Normally I have compassion for things like this, but the lack of documentation and the fact that the error continues to exist since what i can see 2015, across any number of versions is crazy!

    On my case, just not works in the last version of Google Chrome.
    I tested with Unity 2019.3.13

    Using 2019.3.10f1 : I built a scene with the same video played one as "camera far plane" and one as a render-texture applied to a plane. I am playing the videos as urls and uploaded them, so not a streaming-asset. Both videos are roughly the same small size of 5mb and both are mp4s. One of them is the big buck bunny video (the one having more problems).
    In Chrome one video plays most of the time! on both instances (camera far plane and rendertexture/material/plane). Sometimes it doesn't play on the camera far plane and sometimes not on the textured plane. What seems to help, is to manually add a "prepare()" function... most of the times. The other video is never played in chrome.

    In Firefox both videos play most of the time! (not reliable enough to actually ship my project to customers) on both instances, but there is massive stuttering (on an highend-gaming pc the same as on a cheap android phone).

    Would love this to be fixed, as I am relying on this for my current project.
