Bug ID: 164540
Summary: HLS WebGL video textures produces faulty colour
rendering in IOS 10
Classification: Unclassified
Product: WebKit
Version: Safari 10
Hardware: iPhone / iPad
OS: iOS 10
Status: NEW
Severity: Normal
Priority: P2
Component: WebGL

Regarding #163866
I am separating this into a different ticket but they might be related to the FlipY bug.
I was able to successfully test the HLS webGL rendering on an Iphone after the FlipY work arounds. The simulator was causing similar colour faults, but when using the RGBA format flag, the output I see on the Iphone is the same regardless which RGB format is used.
The colours are rendering incorrect. Using this code
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGB, gl.RGB, gl.UNSIGNED_BYTE, video);
If there is a quick fix work around rather waiting months for fixes that could be a start.
So such HLS webgl output is only partially working on IOS 10 not IOS 9. Many devices are stuck on 9 now like my Ipad 3. I need to find a work around for 9.
