1322694 - WebGL video textures fail to render in Firefox Nightly for MP4 format with 2048x1024 pixels dimensions

Status: UNCONFIRMED

(Core :: Graphics: CanvasWebGL, defect, P3)

Description

[AlteredQualia]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20161209030212

Steps to reproduce:

Visit in Firefox Nightly 53.0a1 (2016-12-09):

http://alteredqualia.com/xg/examples/webgl_video_performance_MP4_1024p.html

Observe both tab content and JS console. 


Actual results:

Video rectangle is black. 

In JS console there are repeated errors (presumably every frame):

Error: WebGL: texImage2D: Failed to hit GPU-copy fast-path. Falling back to CPU upload.
Error: WebGL: texImage2D: GetAsSourceSurface or GetDataSurface failed after blit failed for TexUnpackImage.


Expected results:

There should be shown video of clouds.

This test still works ok in the current stable Firefox 50.0.2, so this seems to be a regress.

Also notably MP4 format but with 1920x1080 pixels dimensions and VP9 format with 2048x1024 dimensions do work ok in Firefox Nightly:

Thanks for the bug report!  Any change you could run a mozregression tool and help find out the change that regressed this?

Comment 2

That's a nice tool ;)

I found something, though not sure if this is the same issue. It also fails to render that test video, but the error message is different than what I get in the latest nightly.

Bisect-found range fails with this message:

Error: WebGL: texImage2D: Desired upload requires more data than is available: (4294967295 rows plus 0 pixels needed, 0 rows plus 0 pixels available)

Latest nightly fails with this message:

Error: WebGL: texImage2D: GetAsSourceSurface or GetDataSurface failed after blit failed for TexUnpackImage.

Can you attach the graphics section of about:support?

I have this video playing in nightly on Windows 10, NVIDIA GeForce GTX 960M, 21.21.13.7619.  There are definitely problems with the format (we had to reformat 0x1907 -> 0x1401, end up with video with a non pre-multiplied alpha) that makes things go slow.

Hmmm, interesting. I tried it on another notebook and there it worked too.

Here is graphics section of "about:support" for machine where it doesn't work (Windows 7 64-bit, Nvidia Quadro 2000M):

Besides different Windows versions and bit more up-to-date Nvidia driver, what jumped for me was:
