[Solved] Chromium Pepper Flash freezes on fullscreen -Enlightenment 18

rabcor · 2014-02-05 01:42:22

When playing flash videos in chromium w pepper flash (stable from AUR), if I set them to fullscreen then in 2 or 3 seconds the video will freeze (but sound will still play).

This seems to be related to hardware acceleration, when I disable hardware acceleration for flash it doesn't freeze like that anymore.

But I really want hardware acceleration to be enabled :I

What's wrong? and how do I fix it? (How do I even troubleshoot it?...)

Additional info is that i've got an Nvidia GTX 670 GPU with proprietary drivers and am using enlightenment 18 as a DE.

Solution: Settings->Composite->Rendering->"Don't Composite Fullscreen Windows" (Untick)

Have you tried with the normal flashplugin package? With Nvidia HW, you should be able to use acceleration by setting it in /etc/adobe/mms.cfg.

Otherwise, if you want to stick with the pepper flash plugin, you are ging to have to find some kind of output or logs. Maybe run chromium from the command line and see if it tells you anything?

Nah command line tells me nothing complains a bit about my sound configuration, but I don't have sound issues (and muting doesn't help with this issue either)

And I want to stick with pepper flash.

There is not a 100% chance of this happening btw.. more like 80 or 90%, sometimes the vids keep going even in fullscreen. When they do keep going I usually see a white box appear for a millisecond

Maybe try this part from the wiki https://wiki.archlinux.org/index.php/Flash#Flash_Player

Fullscreen fix for GNOME 3
If you have problems with Flash's fullscreen-mode (video freezes but audio keeps playing), then it's probably because the fullscreen flash window is displayed behind the browser window. This is a known upstream bug in mutter. You can easily fix this by using devilspie:

Could be that it's not only limited to Gnome 3

Thanks for the hint, imma try that one.

Edit: I tried this one (added the config file and started devilspie) it didn't work, will see if I need to restart X for it to work.

Edit2: Nope, this did not work

Update: It seems that disabling "Allow Flipping" (<- What does this even do?) in the nvidia drivers fixed this. I'll re-check tomorrow to confirm (but if you have any ideas keep them coming)

straight from http://us.download.nvidia.com/XFree86/L … ngubb.html

Flipping: When OpenGL flipping is enabled, OpenGL can perform buffer swaps by changing which buffer is scanned out rather than copying the back buffer contents to the front buffer; this is generally a higher performance mechanism and allows tearless swapping during the vertical retrace (when __GL_SYNC_TO_VBLANK is set).

Basically the issue is that "Allow Flipping" isn't working correctly I think, which could be E18 related or driver related, I'd like that option to be on too D:

Any ideas? (I'm going to try another WM; Openbox tomorrow)

Edit: No it wasn't that option; I guess it was just toying with the drivers that somehow managed to temporarily fix it.

Edit2: I found the actual culprit! Settings->Composite->Rendering->"Don't Composite Fullscreen Windows" was on, I disabled that one and stuff seems to work now.
