Attachments:	Radeon deadlock with Flash + VDPAU

Description Marco Trevisan (Treviño) 2014-05-12 23:48:31 UTC

Created attachment 98951 [details]
Radeon deadlock with Flash + VDPAU

1) Enable VDPAU support in flash player [1]
2) Visit web pages such as [2] (in that page the hang happens
   when the AD has been played and the actual video should start).

At this point the flash player hangs (plugin-container process with firefox), and there's no way to resume it other than killing the parent process.

It seems like a deadlock, see the attached backtrace; not sure if this has something in common with Bug 70123.
This is when using mesa 10.1 (4a86465) in Ubuntu 14.04.

[1] echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" >> /etc/adobe/mms.cfg

Ah, this is not happening when using intel, then I suppose this is not an issue of the flash blob.

Comment 2 Grigori Goronzy 2014-05-13 00:18:25 UTC

It's not happening with Intel because the drivers don't support VDPAU.

Yes, of course... But I meant using the VDPAU support thought va_gl.
Also if VDPAU is not using mesa, in that case, I guess that if the problem would be in flash, then it would have hanged even when using va_gl, isn't it? :o
