Status: RESOLVED INCOMPLETE

(Toolkit :: Picture-in-Picture, defect)

Description

Attachment: firefox-modal-problem.jpg

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Sometimes, when I play youtube videos and open PiP Modal, the modal frequently closes. I've observed that log bellow in the terminal when the modal closes, because I have the habit of open the Nightly from Linux terminal.

The log who appears when Youtube PiP modal closes:

"""ts
[Child 30997, MediaDecoderStateMachine #3] WARNING: Decoder=7f1fa4247e00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166
[Child 30997, MediaDecoderStateMachine #3] WARNING: Decoder=7f1fa4247e00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166
"""

• Open youtube video. Like: https://www.youtube.com/watch?v=psunHk5kWvQ (Live)
• Click in the PiP modal button
• The PiP modal opened
• Sometimes the modal closes and need to be opened again
• The error appears in the linux terminal

Actual results:

Youtube modal closes sometimes.

That warning appears when PiP modal closes:

"""js
[Child 30997, MediaDecoderStateMachine #3] WARNING: Decoder=7f1fa4247e00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166
[Child 30997, MediaDecoderStateMachine #3] WARNING: Decoder=7f1fa4247e00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166
"""

Expected results:

• Don't close the modal, keep the PiP video modal opened
• If the modal closes for some reason, automatically reopen the PiP
• Reopen the PiP modal if closes after error or warning

Thanks!!!

Hi there, thanks for the taking the time to report this bug.

@Wellington Torrejais de Silva - unfortunately, from the log alone, I can't tell what could've caused the PiP modal to close unexpectedly. It would help us greatly if you could answer the following questions:

• Does it occur only for that one video that you linked? Or do you see the same behaviour for other videos too?
• If you can reproduce with another video easily, would you be able to run the profiler when it happens and then send us a link to the profile?
• Does it happen again after making a new profile? (See how to make a new one here)

Thanks!

Also @alwu - do you happen to know what usually triggers the error logged above?

That indicates a decode error, but it could be caused by many different reasons. It would be great if you can help us capture a profiled result as well (if you can reproduce this issue steadily)

Closing due to lack of response from the reporter; if you can provide the requested information, then we can have another look, but right now as kpatenio said there isn't enough here to work with.

Hi,

Sorry for the delay.

The problem occurs when the system resources are on high usage.
Appears to be a browser managing resources and reallocating that resources on the tab who runs the video, closing the PiP modal in the proccess.

Thanks!
