[Bug 1774915] Re: Video freezes and stutters when using totem (audio continues fine)
*** This bug is a duplicate of bug 1698270 *** https://bugs.launchpad.net/bugs/1698270 Charlie, yes I would recommend using mpv instead of totem. mpv will perform better and is the only other video player that will take advantage of Intel hardware acceleration properly [2]. I do _not_ recommend gnome-mpv [1] and also do _not_ recommend vlc because it seems to be lacking in hardware acceleration. I have no experience with SMPlayer, but please see also [2].

[Bug 1774915] Re: Video freezes and stutters when using totem (audio continues fine)
Sorry for the long delay in responding - had to wait for some other things to finish so I could switch from Xorg to Wayland. The same types of pauses/lags/freezes happen to me under Wayland using mpv as were happening under Xorg. They may be slightly less frequent (subjective judgment, no actual counts done), but they still occur. Also, I find that I am unable to close mpv under Wayland. Alt-F4 does nothing, nor does going to the Window menu and choosing Quit. The video continues, and I am not sure exactly what else to use to close it (other than just waiting for it to finish running) - I don't know much about mpv. Closing wasn't a problem under Xorg - either of the two methods mentioned above worked there. Just throwing that out there for consideration. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1774915] Re: Video freezes and stutters when using totem (audio continues fine)
Before we merge this bug into bug 1698270 I would like to hear Tracy's response to comment #25. Then I expect we will need/want to get more of the above lists of gnome- shell performance issues fixed before we can confidently say this issue exists purely within video playback. P.S. If the problem is purely a video playback issue then my suspicion is that some component is implementing frame dropping incorrectly. If it is implemented using double buffers then you can easily starve the screen of new frames while repeatedly (racily) replacing the backbuffer. The right approach then is to use 3 buffers and the mailbox algorithm.

Sergei, "performance" is a general category of problems that includes dropped frames. For example, in gnome-shell I have separated those issues: https://trello.com/c/Q6JYXPPs from the ones that incur measurably high hardware usage: https://trello.com/c/pe5mRmx7 A low frame rate is still a performance problem even if it's not stressing the hardware. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I've checked iowait using iotop during lags and revealed no spikes or something like that. So it's not a performance problem at all. I believe gstreamer is just dropping frames due to some bugs.

Totem and gnome-shell both are running between 10% and 30% each (they bounce back and forth during playback). The next highest usage (according to top) is 8% and under.

Thanks, but there's no need to benchmark the CPU itself. We already know the CPU model.

OK, so I tested the removal of the items requested (still with BIOS set to fixed). After > sudo apt remove mesa-va-drivers I tried running the video in totem. Same problem as before - random lags/stutters/freezes, usually < 1 second, but a few that were longer (longest was about 2.5 seconds this time around). So then I tried > sudo apt remove i965-va-driver then ran the video in totem. If anything, the problem became worse - the lags were more prevalent, and the longest was > 3 seconds. So I went back to mpv and ran the video there. There were minor stutters (not long enough to call them lags - I would estimate they were mostly < 0.25 seconds) scattered through the video at random, but none long enough to really cause me to say "this is unwatchable". However, I did notice increased CPU usage - the system became noticably warmer to the touch while the video was playing, and the fan kicked on high to cool it (previous instances I didn't notice the fan kicking on - perhaps it did, and I just didn't notice it. I have copied below the terminal output for mpv, in case any of it is relevant (I didn't notice much different than the past - just a warning about a decoder not supporting hardware). I can re-run and see if I can catch a lag long enough for me to start dmesg if you like.

[Bug 1774915] Re: Video freezes and stutters when using totem (audio continues fine)
I don't see any changes in vainfo from before the change to the BIOS to after. I have posted both versions here, in case I missed something.

[Bug 1774915] Re: Video freezes and stutters when using totem (audio continues fine)
Ah! Your kernel log mentions the AMD video decoder here: [ 1223.799908] [drm] UVD initialized successfully. So it's possible that's the cause of the main problem. Can you please reintroduce the bug and run 'vainfo'? Does 'vainfo' report different information after you switch your BIOS? If that is the problem then the workaround should be: sudo apt remove mesa-va-drivers -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

By the way, I also set up Ubuntu 18.04 on a very similar HP machine last night (Intel Sandy Bridge + Radeon graphics) and can not reproduce any problems. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Thanks. What you are experiencing is worse than I have ever seen. We do have a catch-all bug 1698270 to cover similar issues, but I am not aware of it ever being as bad as you describe. Maybe this problem is specific to the VAAPI decoding that is common to both totem and mpv... Does the problem go away after running this?; sudo apt remove mesa-va-drivers If the problem then continues, how about after also running this?; sudo apt remove i965-va-driver ** Summary changed: - Video lag when using totem (audio does not lag) + Video freezes and stutters when using totem (audio continues fine) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
