I have tried to connect to a Google Meet session from my F-30 ppc64le workstation. It works only partially, I can hear the audio, but there is no video. There is nothing in the terminal except 2 "Gtk-CRITICAL **: 10:45:55.051: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed" messages. How can I get to the reason why there is no video? Shall I try with a debug build? Version-Release number of selected component (if applicable): firefox-74.0-3.fc30.ppc64le
Please run firefox with G_DEBUG=fatal-criticals under gdb (firefox -g -d gdb) and attach the backtrace here, see: https://fedoraproject.org/wiki/Debugging_guidelines_for_Mozilla_products#Application_crash gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed" usually means null pointer is passed to gtk_widget_get_window().
Martin, thanks for the info. The "gtk_widget_get_window: assertion" looks harmless, there is no crash registered, but the message appears when I confirm/select the "microphone" permissions (I have no camera attached). I guess I'll buy a web camera and prepare a debug build before my next attempts :-) I'll keep you informed. I have tried sharing a window from the ppc64le machine and it works = was seen correctly on the other machine in the Google Meet session (my x86 laptop). In testing with a Bluejeans session, I see the same "gtk_widget_get_window: assertion" message when it should start to receive the video stream from the other host. So there is likely a relation between the message and displaying the video.
a progress report from last week - with locally built FF from trunk I can passively use Google Meet (can receive both audio and video), no change with Bluejeans. I'll keep you updated when there is something new.
This message is a reminder that Fedora 30 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '30'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 30 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
