Status: NEW

(Core :: Audio/Video: GMP, defect, P3)

Description

[Simona Badau, Desktop QA]

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:69.0) Gecko/20100101 Firefox/69.0
Build ID: 20190812173625

Steps to reproduce:

1. Launch Firefox
2. Navigate to Amazon Prime and log in
3. In different tabs, open 3 amazon videos
4. After a while (approximately 10 minutes) close the 3 videos

Expected results:
After step 3, a plugin-container process is running. After the videos are closed, the plugin-container process is closed.

Actual results:
Sometimes, after the videos are closed, the plugin-container process remains opened.
The issue is intermittent, I managed to reproduce it so far on Mac OS X 10.9, Mac OS X 10.10 and Mac OS X 10.12 using Firefox 69 beta 14.

As this issue is intermittent and seems only happening on certain OS versions (I couldn't reproduce it on Night70 on Mac OSX 10.14), I will mark this bug as P3 temporarily.

Bryce,
Do you have any idea about this issue?
Thank you.

Sounds like an issue with the gmp machinery not getting signaled appropriately, but beyond that I don't have any immediate insight.

Simona, when you say close the 3 videos, you're closing the tabs with those videos in them?

Yes, I'm closing the tabs with the 3 videos in them.
