Videos on Udemy have been unplayable for some time now (I believe the issue arose after one of the latest WebKit or GStreamer updates).


??? Maybe can be related to https://bugs.webkit.org/show_bug.cgi?id=221622 ??? Not sure.

We'll need pipeline dumps.

I don't have a udemy account.

https://www.udemy.com/course/fearless-public-speaker-bootcamp-by-ricky-mendoza/ plays fine here.

It doesn't work for me

Which versions exactly?

If you're not using one of the Ephy flatpaks I don't think I can help further, sorry.

Your log shows no error.

Preview course videos play fine here in Ephy TP.

Two attempts today:
- the first one worked fine and the video started immediately;
- the second one the video stays on forever (like most of the time).

I'm on Epiphany 47.2 (WebKitGTK 2.46.3, GStreamer 1.24.9) on Fedora (rpm)

[Philippe Normand]

I also tested WebKit main with gst 1.24.9.

The only regression I can think of, due to gst 1.24.9, is https://commits.webkit.org/286347@main which will ship in 2.46.4 (afaik).

Ok thanks for the clarifications.
I'll update you if anything changes.

2.46.4 does not solve the issue

[Philippe Normand]

Please try the Flatpak Ephy TP.

[Angelo Schirinzi]

Same issue on newer Epiphany/WebKit/GStreamer and, yes, Ephy TP is also affected.

https://www.udemy.com/course/fearless-public-speaker-bootcamp-by-ricky-mendoza/ works for me now, but video courses don't start (to be precise, they start once in ten times, approximately).

[Angelo Schirinzi]

I have another observation to make: the preview videos and the advertising videos are always playable now; the problem only occurs with the course videos.

Can you share the JS console log?

[Michael Catanzaro]

Doesn't Udemy require Widevine? There is no way that will ever work.

[Philippe Normand]

I have no idea since I don't have an account for this and can't test myself.

Indeed this site requires EME I'm afraid. Closing, sorry!
