Description

[alexis.le-boucher]

Attachment: 4742fdd8-aefa-4724-aa37-9b55f7165ea2.mp4

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:105.0) Gecko/20100101 Firefox/105.0

Steps to reproduce:

I try to play an mp4 video in Firefox:
https://woopen.s3.eu-central-1.amazonaws.com/uploads/336bdd9f-62f6-40e0-8a12-89fe082ff2e1.mp4

I tried to clear my cache and restart Firefox
I tried to deactivate the recommanded performance settings and the hardware accelation and restart Firefox
I tried to deactivate the website protection on this website (the shield icon in adress bar).

I can see the video in Chrome or Safari

Actual results:

The video is not displayed. We can see the video player and hear the sound but the video is not displayed

Expected results:

I should see the video

Comment 1

[alexis.le-boucher]

I attached the video that is not displayed in Firefox in my ticket.
If I go to the ticket url in Firefox, I cannot see the video in my ticket but if go to the ticket url in Chrome, I can see the video in the ticket.

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can confirm, on my Linux machine the provided media file crashes Firefox nightly outright. Looks related to cubeb:

Comment 4

[Matthew Gregan [:kinetik]]

The video playback issue is caused by Firefox not supporting the HEVC (H.265) codec, so I'll dupe this to bug 1332136.

The cubeb assert is not directly related. It can only be triggered in debug builds when cubeb logging is enabled. I'll file a separate bug to fix that.

[alexis.le-boucher]

Hi, will the bug be fixed ? I saw it has been closed and linked to a RESOLVED WONTFIX ticket.
Thank you
