Chromium's MPRIS implementation freezes and then crashes the browser when trying to play any video with Laine gnome-shell extension

[BavarianPH]

(upstream bug report: https://bugs.chromium.org/p/chromium/issues/detail?id=983203)

Ubuntu 18.04
I expect Chrome to play videos.
When I try to play any video on Google Chrome for Linux, any version of 75 or higher, Google Chrome freezes.
Chrome 75 will allow sound but no video.
All mouse clicks become unresponsive.
Attempting to close Chrome after many mouse clicks causes Chrome to crash.
Even worse it often also crashes Ubuntu 18.04.
Google Chrome 74 or lower work without any problems playing videos.
It is a Google Chrome Linux version 75 or higher problem.
I cannot believe that neither Google or Ubuntu or any other Linux OS seem to completely ignore this extremely serious problem.
I am forced to install Google Chrome 71 to fix video playback problem.
I posted on Ubuntu ask, and show over 90 views but no comments.
One answer confirms that he has the exact same problem.

Chromium version 75 has the exact same video issue as Google Chrome 75.
It freezes when I try to play any video.

Since chrome is also affected, would you mind filing an upstream bug at https://crbug.com, and sharing the link to it here?

Also, can you run chromium from a terminal like this, reproduce the problem and attach the full output?

    chromium-browser --enable-logging=stderr --v=1

Thanks!

[BavarianPH (bavarianph)]

chromium-browser --enable-logging=stderr --v=1
When I reproduce the problem chromium 75 and Ubuntu 18.04 freeze.
After many mouse clicks chromium and Ubuntu 18.04 crash.
There is no output from the terminal because it also crashes.
Chromium does not produce an error report because it is frozen and crashes before it can make a report.
Are you telling me that nobody else has these same severe problems?
How can chrome and chromium 74 and older work perfectly and versions 75 freezes and crashes.
It is a chromium and chrome 75 issue, and not a Ubuntu 18.04.
Filing a bug with https://crbug.com is too complicated.
I am not a developer, I just need chrome and chromium to work.
Please contact the developers of chrome and chromium 75 and have them work on this, instead of hiding this insidious issue.
Why don't you use Ubuntu 18.04 with firewall on install chrome and chromium 75 and see what happens.
I am tired of solving other peoples errors.
I will just continue to use chrome 71 till google and chromium decide to fix this very well known issue.

[BavarianPH (bavarianph)]

This bug report is only incomplete because I am unable to reproduce the issue and get output.
Not getting usable error output or an error report IS part of the issue!

[BavarianPH (bavarianph)]

I just filed a bug report on https://crbug.com/

[BavarianPH (bavarianph)]

I just discovered that I can play audio but chromium freezes as well.
Also after clicking in chromium many times chromium crashes, and Ubuntu crashes but not always.
It seems that in chromium 75 the media process is started and then blocked.
Whatever they added to control media playing seems to be the issue in version 75.
Windows 10 chrome 75 seems to work fine

Comment #1 on issue 983203 by <email address hidden>: video playback fails and freezes chromium and Ubuntu and then crashes
https://bugs.chromium.org/p/chromium/issues/detail?id=983203#c1

Sorry we don't provide support for Chromium builds. You'll need to see if the issue reproduces with an official Google Chrome build:
https://www.google.com/chrome/

The official build should generate a crash report in chrome://crashes then. Have you tried this?

[BavarianPH (bavarianph)]

chrome://crashes does not give a crash report after chrome 75 freezes and then crashes
HELP!
chromium 75 is the same, no crash report

[BavarianPH (bavarianph)]

since I cannot give a an error report about chromium or chrome
You cannot possibly say that my bug report is incomplete.

[BavarianPH (bavarianph)]

I now have 100 people look at my ask ubuntu question.

https://askubuntu.com/questions/1152145/how-to-repair-chrome-75-video-playback-with-freezes-and-crashes?

Apparently they do not have a solution either.

Is anyone taking this serious?

[Olivier Tilloy (osomon)]

Thank you for filing an upstream bug.

Your issue is being treated as seriously as other incoming bugs. The problem right now is that triagers haven't observed or managed to reproduce the problem, which makes it difficult to know where to start. No one else has reported similar issues on Launchpad either, so the bug you're experiencing doesn't seem to be affecting many people (fortunately).

Can you browse to chrome://media-internals/, click the button to save the logs, and attach the log file here? Thanks!

What changed about video and audio playback on version 75 of chrome and chromium?

As I said before any earlier version worked just fine.

In chrome or chromium 75 when I click on any video to play, the moving circle appears and then
freezes instantly, as if it is stopped on purpose.
It may have to do with the process that stops videos from automatically starting until one clicks on the play arrow.
Except in this case clicking on a video is treated as if it were a automatic video start?

I still cannot believe that no one else has reported this issue.

my askubuntu question:

https://askubuntu.com/questions/1152145/how-to-repair-chrome-75-video-playback-with-freezes-and-crashes
has had 103 views, which leads me to believe that at least over 100 users are affected.

[BavarianPH (bavarianph)]

I suppose many Linux users probably use Firefox as a browser.
And I can use the newest version of Firefox to play videos without any trouble.

But with chrome and chromium 75:
Even after deleting all files and programs related to these browsers and starting totally fresh,
video will not play and freeze the browsers.
Could it be my nvidia drivers?
But even audio play freezes.
So it appears that all active media is affected on versions 75 and up, including beta and unstable versions.

[BavarianPH (bavarianph)]

Bug solved!

In my case, the Laine gnome-shell extension was causing all the problems. when I turned the Laine extension off both google-chrome and chromium versions 75 (newest updates) worked again.
Both video and audio playback ran normally again.

[Olivier Tilloy (osomon)]

Thanks for the feedback. I'm closing this bug accordingly.

Note that "Delete this seriously flawed extension!" (on https://extensions.gnome.org/extension/937/laine/ and https://gitlab.com/jhoran/Laine/issues/52) is not usually considered constructive feedback. I'm sure the developers of that extension will be more than happy to investigate and fix the problem, now that it has been reported to them. Wording the report in friendly terms wouldn't hurt.

[BavarianPH (bavarianph)]

I am sorry about suggesting to delete the extension. One can also turn off the extension until the developer has found a fix. It seems that the use of MPRIS and Pulseaudio may be causing a conflict with Chrome and Chromium version 75 and newer. Any older versions seem not to be affected by the use of Laine.

[BavarianPH (bavarianph)]

In my case, the Laine gnome-shell extension was causing all the problems.
when I turned the Laine extension off both google-chrome and chromium versions 75 (newest updates) worked again.
Both video and audio playback ran normally again.

It may be an MPRIS or pulseaudio, or other gnome-shell media extension interaction with chrome or chromium 75.

this link may have further answers.

https://bugs.chromium.org/p/chromium/issues/detail?id=983203#c24

There really is a bug, so I do not understand why this bug report is invalid.

The above web link tells you that there is a bug!

[Olivier Tilloy (osomon)]

So this is indeed a bug in upstream chromium. Correcting the status accordingly.
Unfortunately launchpad is not able to track remote bugs at bugs.chromium.org, so we will have to update the status again once the fix is released.

MPRIS: Return list of artists instead of an artist string

This CL changes the MPRIS artist metadata to be a list of strings
instead of just one string. This makes MPRIS correctly match the spec
of the xesam:artist property. This fixes an issue where some users of
MPRIS (e.g. the Laine GNOME extension) would crash when reading the
xesam:artist value since they assume it's a list instead of just a
string.

Tommy Steimel commented:

Chrome 75 doesn't correctly follow the spec for the xesam:artist attribute. It's supposed to be a list of strings, but Chrome just returns a string. I have a fix out for that here: crrev.com/c/1715233. Some MPRIS clients gracefully handle that case though, so it may be worth updating Laine to not break when given just a string. Thanks!
