However, regarding the example 2. and 3.
Sometimes, when i click the "reload button", then i can see the video and vice versa.

Comment 2

I've googled and found a solution.
Somebody mentioned how to fix this:

Solution:

about:config

media.hardware-video-decoding.failed

set it to "true"


Man, you guys work slow, no wonder why Firefox sucks and Chromium rocks.

Looks like a hardware decoding issue. I think Chrome have this driver disabled[0] for video decode specifically.

Matt, do you have a suggestion as to how to approach this? Is this something the sanity test could be expanded to catch?

Guys, i have made a final decision:

Because Firefox uses over time too much RAM and doesn't free it and because of the very bad hardware support, extreme bad audio/video/media playback support, i have deinstalled Firefox forever.

I will stay with Chromium that doen't have these problems at all.

I won't post here anymore, nevertheless i wish you all the best.

We'd need a super simple video (to simplify verifying that it looks as expected) that reproduces the issue.

Do you have access to hardware that reproduces the problem.

Jeff, do we have anything like this in Toronto?

Otherwise we can just add a blacklist entry similar to this one: https://searchfox.org/mozilla-central/source/widget/windows/GfxInfo.cpp#1279

[Jeff Muizelaar [:jrmuizel]]

Yeah. We have a AMD Radeon HD 3650. I can take a look on Monday.

Comment 7

[Jeff Muizelaar [:jrmuizel]]

I can reproduce this locally. In fact I even got a kernel panic in the ati driver while watching twitch.

Comment 8

[Jeff Muizelaar [:jrmuizel]]

Interestingly enough though, I can only seem to reproduce the problem with the twitch video. The other videos seem to play fine.

Comment 9

[Michael Froman [:mjf]]

Should this be marked confirmed?
