Can' watch Twitch streams. Sound work but I see only back screen video

[AngryPenguinPL]

Like in title, when I trying watch Twitch streams I not see anything in player. Player start fine with loading circle and after that I see only black screen video but sound play fine. This happend only on Twitch (other Flash site with video content workinig fine).

Anyone know how to fix it?

I tried now, video is visible on my setup. I even tried to remove old NPAPI Flash, but it still works. (Last time, in #273, presence of NPAPI Flash masked issue for me).

Various bits of environment can affect the issue. I'll try to list what I believe is relevant:

• Firefox version;
• freshplayerplugin version;
• PepperFlash version (at least ensure it's latest);
• desktop environment or windows manager;
• presence of NPAPI Flash (11.2);
• enabled addons, like AdBlock+, HTTPS Everywhere, Greasemonkey with enabled scripts and so on;
• Linux distribution and its version;
• 32/64.

(I can't think about anything else related.)

In other question.

Browser version: Firefox 48 x64 from Mozilla site (Official Mozilla build, not from system repo) Freshplayerplugin version: freshplayerplugin-0.3.4-1.mga5 (only this version I can get fromn system repo) PepperFlash version: latest from Chrome Desktop environment: KDE4 +KWIN Presence of NPAPI Flash (11.2): Yep, but I trying also remove it and still is the same Enabled addons: Yep, uBlock but with disabled it is still the same. Linux: Mageia 5 x64 (derivates from Mandriva, it use urpmi+rpm)

Also I use AMD Radeon HD GPU with fglrx driver (Catalyst 15.9). In evening I will try to check another computer with Ubuntu + Mageia 6 development.

Freshplayerplugin version: freshplayerplugin-0.3.4-1.mga5

Could you try to build version from repository?

[fresh] [error] [NP] caught Xlib error 8

I think, some Xlib call fails due to unsupported combination of parameters. But before going there, it's worth to try newer freshplayerplugin version. Perhaps, some of the changes fixed that. Last released version was 0.3.5, and there were changes after that.

doesn't Twitch use HTML5 playback nowdays...or was it still optional/beta? I haven't checked that for a while when I moved to orion (3rd-party twitch app, qt5 based)

Checked right now — Twitch now offers HTML5 player as a beta test. HTML5 is now enabled by default, and it works. Old Flash-based player is still available, but one needs to explicitly turn it on.
