1911283 - [Windows] Videos on Hulu fail to play

Status: VERIFIED FIXED

(Core :: Audio/Video: Playback, defect, P1)

Description

[Ciprian Georgiu, Desktop QA]

Found in

• 129.0 RC2

Affected versions

• 129.0 RC2
• 128.0 RC2

Tested platforms

• Affected platforms: Win 10 x64
• Unaffected platforms: macOS and Ubuntu

Preconditions

• The user is logged into Hulu

Steps to reproduce

1. Navigate to https://www.hulu.com/ and attempt to play any video.

Expected result

• The video is correctly played back.

Actual result

• The video fails to play and loads endlessly.

Regression range

• This issue does not appear to be recent regression; it also occurs in Firefox 128-build2.

Additional notes

• Interestingly, the issue does not repro with the latest Nightly build. In Nightly, DRM content is detected as soon as the link is loaded. However, in Firefox 129 and 128, the DRM icon does not appear in the URL bar, as the issue persists.

Could anyone help me turn the pref media.eme.mfcdm.origin-filter.enabled to 0 to see if that fixes the issue or not? Thanks!

This fixed it for me. I put it back to 1 again and confirmed Hulu stopped working again. Back to 0 and works.

Thanks! I will submit a patch and uplift it to other versions! Sorry for the inconvenience!

Comment 9

[Alastor Wu [:alwu]]

In addition, bug 1896948 was landed on Fx129, so the issue in Fx128 is not possible caused by that. If we do have an issue on Fx128, that will be a different issue and please file another bug to track it.

This might be a stupid question, but where do I find that preference? Thank you so much and sorry if I'm wasting your time.

Type about:config in your URL bar. Then accept I'll be careful on the warning. Then copy the name of the preference and put in that search bar. Once it comes up edit the 1 to 0

Thanks for the confirmation! Would you mind help me do more testing? From your profile in the comment4 , the issue happens on Fx129 for you. Does this also happen on the official Nightly for you? And this is another new build, would you also see error on this build? Thank you so much!

Sorry for the delay, storm was coming through.

Nightly works without issue. I've uploaded the profile in case you needed it.

The bug is marked as tracked for firefox129 (release), tracked for firefox130 (beta) and tracked for firefox131 (nightly). However, the bug still has low severity.

:jimm, could you please increase the severity for this tracked bug? If you disagree with the tracking decision, please talk with the release managers.

I investigated this issue on Win 10x64. Here are my results:
Fx 129.0 - video fails to play: https://share.firefox.dev/4dgymby.
Nightly 131.0a1 - video works as expected: https://share.firefox.dev/4fGvpCA
The new build from comment 19 - an error message is displayed: https://share.firefox.dev/3WWLdtL

Comment 24

[Jim Mathies [:jimm]]

This impacts some content on the site, but not all. Trying to find a regression range has been tricky. The media.eme.mfcdm.origin-filter.enabled pref doesn't seem to be tied to this in nightly. Alastor says this is another issue with experimental hevc support.

FYI flipping media.eme.mfcdm.origin-filter.enabled=0 in release seems to fix it.

Revision D218867 was moved to bug 1912496. Setting attachment 9418376 [details] to obsolete.

Comment 29

[Jim Mathies [:jimm]]

Not all content on Hulu is impacted by this. Mostly animated TV episodes. Movie content from providers like HBO plays properly. We've confirmed the pref flip addresses the issue.

Note for QA, testing in Nightly requires you flip the experimental hevc support off by setting media.wmf.hevc.enabled=0. Hulu has other issues with that setting that can interfere with testing.

I've tested this fix on the latest Nightly 131.0a1, Beta 130.0b4, and Firefox 129.0.1 on Windows 10 x64. I can confirm that all the Hulu videos tried played correctly. On Nightly, I checked with the media.wmf.hevc.enabled preference set to 1 and 0, and the videos worked as expected in both cases.

Hello, I wonder if you would mind to help me check this build again to see if the issue still persists or not? Thank you so much!

Hi, just gave it a try. I get Error code P-Dev313 on Hulu. The current version of Firefox 129.0.1, works fine.

I don't know if my result is still useful but I was out. For build from comment 38 I get the same Error code P-Dev313 as per comment 39 from Jason.
