Call for testing: Video playback in 18.04

vanvugt · February 7, 2018, 1:43am

Thanks all.

Yes, I meant Intel CPUs but if some AMD work then that’s a bonus.

Please note that I am only asking for testing in Totem and MPV. Not Gnome-MPV, Kodi or VLC. To the best of my knowledge the latter ones either don’t use acceleration (properly) or have other performance problems. So I’m only declaring Totem and MPV as supported right now. Remember; if it’s using high CPU at all then acceleration isn’t working.

If you can reproduce any problems with ‘mpv’ then please also paste the terminal output that command produces when playing a video.

If you can reproduce a problem that’s specific to just one player then please also help by logging a bug against that player. Only totem or mpv for now.

gst-play-1.0 and mpv plays with hardware acceleration (~5% cpu) without slowdowns.

Re; mpv in wayland & screen blanking
screen blanking is not inhibited in mpv while using wayland . Likely there is no solution for 0.27 in mpv itself.
The current mpv-0.28 does implement but thru zwp_idle_inhibit_manager_v1 protocol (wayland protocols) though it’s not implemented in mutter (- https://gitlab.gnome.org/GNOME/mutter/issues/20

Users can start mpv with gnome-session-inhibit mpv /path/to/file & blanking will be inhibited while mpv is open. It can be added to the front of mpv’s .desktop Exec= line with no apparent ill effects if using X11 instead of wayland.

mc3man · February 7, 2018, 9:05pm

Totem vaapi issue in X11 seems be from 1 of 3 mesa packages, see bug report for list

vanvugt · February 8, 2018, 1:54am

All, please avoid discussing too much detail in this topic (bug reports should contain those). And remember gnome-mpv is not recommended, so results from that one are unwanted (see https://community.ubuntu.com/t/hardware-accelerated-video-playback/304/4).

The bugs identified thus far (thanks for being on top of it mc3man), are:

Corrupt video in Xorg sessions: https://launchpad.net/bugs/1747744
Stuttering in stephen-d-allen’s AMD/Radeon case: Probably needs its own bug if not the shell’s fault: https://trello.com/c/Q6JYXPPs
Broken titlebars in rimez’s screenshot: https://launchpad.net/bugs/1745070
gnome-mpv high CPU: Acceleration probably isn’t enabled in that package, but also there’s a GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=787704
Screensaver kicks in during mpv playback in Wayland sessions: https://launchpad.net/bugs/1740771

mpv works fine, low CPU and shows this in output log “Using hardware decoding (vaapi).”
totem does not work, shows black screen, also shows “Using hardware decoding (vaapi).”
Uninstalling the gstreamer1.0-vaapi fixes totem blackscreen.

@vanvugt Let me know if you need any other info.

vanvugt · February 12, 2018, 6:08am

Thanks. The black screen which is probably also a little or a lot corrupt, is https://launchpad.net/bugs/1747744 … We have a fix for that coming soon, probably as a patch on top of the migration to Mesa 18.0.

Yes I forgot to mention that removing gstreamer1.0-vaapi is also a workaround. But not if you’re playing high-end 4K/HDR/HEVC type video, because playing that smoothly is really impossible without hardware acceleration.

I can’t yet see what you mean by weathered colours. Can you please try taking more photos? Particularly of a video for which I would be familiar with already, like:
http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_60fps_normal.mp4
or any of http://bbb3d.renderfarming.net/download.html

Are the weathered colours limited to MPV, or do they also occur in other apps (like web browsers and photo viewers)? I’m thinking maybe you’re hitting https://launchpad.net/bugs/1727232 which I think probably needs more priority. It’s such an invisible issue though many people would not yet realise it’s a bug.

Screenshots might be better actually (just press PrtScn and then look in your Pictures or home directory). It would be interesting to see if taking screenshots averts the issue.

oystein-alver · February 13, 2018, 7:44pm

I can’t yet see what you mean by weathered colours.

“Weathered” is possibly the wrong word; English is my second language. I’ll just call the issue ‘colour artefacts’.

Can you please try taking more photos? Particularly of a video for which I would be familiar with already

The forum only allows me to upload one photo, but here you go (my phone camera is awful, but the colour artefacts aren’t visible on screenshots):

Photo

Look at the sky’s light colours. They display with smooth gradients on Ubuntu 16.04, but as the photo illustrates 18.04 seems to display the video with a smaller range of white colours. This is the most apparent with either very dark or very light colours.

Are the weathered colours limited to MPV, or do they also occur in other apps (like web browsers and photo viewers)?

The issue is definitely system-wide; the artefacts are visible on the desktop, in Firefox (mostly when viewing photos) and other apps I use. Even on window titlebars the artefacts are visible (displayed as lines with different shades of grey/black). It honestly looks like the colour range is improperly configured.

I’m thinking maybe you’re hitting https://launchpad.net/bugs/17272321 which I think probably needs more priority. It’s such an invisible issue though many people would not yet realise it’s a bug.

It’s possible that the issue is related to that bug. But, as I mentioned, my issue is system-wide. And I tried the fix that the bug reported suggested - turn Settings > Devices > Color > (my monitor) = OFF - but it didn’t improve the issue.

Screenshots might be better actually (just press PrtScn and then look in your Pictures or home directory). It would be interesting to see if taking screenshots averts the issue.

As I mentioned, the artefacts are not present on PrtSc shots that are taken on Ubuntu 18.04 but viewed on a different system (16.04 and Windows).

What is most interesting: installing a previous kernel version fixes the issue completely! I used UKUU Update Utility to install kernel 4.4 (the same that I use in Ubuntu 16.04 without issues) and upon a reboot with 4.4 running on 18.04 everything displayed smoothly. So this indicates that there is a regression somewhere in the kernel?

vanvugt · February 14, 2018, 1:38am

That is indeed very interesting and sounds like your system is using a sub-optimal colour depth with the newer kernel. That will cause banding and artefacts.

Can you please log it as a kernel bug? Use this command in a terminal to open the bug:

ubuntu-bug linux

And let us/me know by subscribing user ‘vanvugt’ to the bug.

I don’t think it should be discussed any more here since it’s not a problem confined to video playback.

MPV is jacked up on i7-3770 & xorg. I didn’t even realize until just now testing, always use VLC and haven’t had an issue with 18.04 LTS. It looks the same as @shemgp seems to be taking pieces off my desktop and shuffling in chunks.

vanvugt · February 15, 2018, 1:35am

Please log a bug for that using this command:

And attach screenshots/photos to it.

Totem takes up a lot of CPU resources. However mpv works well.
And in many apps the GPU acceleration is diabled.

We only support hardware accelerated video decoding in totem and mpv right now. And we are aware that totem is still less efficient than mpv. However, I would like to check that you’re not encountering a new totem bug we’re not already aware of. So please run this command to log a new bug:
