More example videos can be found here (most others are geoblocked): https://www.srf.ch/play/tv/sendung/tagesschau?id=ff969c14-c5a7-44ab-ab72-14d4c9e427a9

Here with vah264dec playback works. With libav, decoding errors...

Please provide a debug log, see https://docs.webkit.org/Ports/WebKitGTK%20and%20WPE%20WebKit/Multimedia.html#layout-tests

and set GST_DEBUG="3,webkit*:9,videodec*:6"

srf.ch plays videos using HLS, which has been disabled since WebKitGTK version 2.39.4 https://webkitgtk.org/2023/01/16/webkitgtk2.39.4-released.html. This bug should be closed.

Too bad.

HLS is a workaround. If there is a bug in our MSE backend, it should be fixed.

By changing the user agent to remove Safari, videos now play on srf.ch, rts.ch, and playsuisse.ch (they all have the same issue otherwise).

There are still issues with the video playback though. When starting the playback, it stays still after a few seconds (you need to seek a little little bit back), seeking (more) at any time causes the video to now longer be playable, and it's not possible to resume it.

This should be closed. The issue in the description seems to no longer be one. The website also made changes and no longer requires HLS, which won't be added to WebKitGTK anyway. In short, the issue is not up-to-date.
