vk.com - no video playback

Unread post by motoprogger » 2022-08-13, 10:42

The Russian social network vk.com has a feature of attaching videos to posts/messages. The playback can occur in a number of environments including feed view, popup player or an iframe embedded into a different website. Video playback doesn't work in Pale Moon.
I consider the embeddable iframe the easiest environment to debug, so I provide a link to an example video:
https://vk.com/video_ext.php?oid=-62622 ... afb7d786bc
When attempting to start playback, the web console says:

Code: Select all

16:39:32.451 Unhandled promise rejection Error: No init buffer for starting representation

Works for me.
Probably some extension messes up scripting.

@ motoprogger

I clicked on the link you provided and the video plays for me without any problems.

At this time, I'm using 64 bit linux Pale Moon 31.2.0.1 running in 64 bit linux Mint 20.3 (Una) Xfce. The only extension I use in Pale Moon is uBlock Origin v1.16.4.30 with UBO enabled. I'm also using a lightweight theme named, Moonscape (v7.2.1).
Linux Mint 21.3 (Virginia) Xfce w/ Linux Pale Moon, Linux Waterfox, Linux SeaLion, Linux Firefox
MX Linux 23.2 (Libretto) Xfce w/ Linux Pale Moon, Linux Waterfox, Linux SeaLion, Linux Firefox
Linux Debian 12.5 (Bookworm) Xfce w/ Linux Pale Moon, Linux Waterfox, Linux SeaLion, Linux Firefox

OK, this turned out to be an automatic playback blocking extension interfering. I have checked it with Toggle Autoplay and Autoplay Whitelist. Both work with youtube.com, but not with vk.com.
Is the development of those extensions connected with the development of Pale Moon in any way? Otherwise, how do I find the authors' contacts in Pale Moon user interface?

Look int he add-on manager for information about the extensions. if it doesn't include information that allows you to contact them and there's nothing on the addons site for it, then there's no real way we can help. Maybe some other users have information that allows you to contact them.

Two extensions I have tried are:
https://addons.palemoon.org/addon/autoplay-whitelist/
https://addons.palemoon.org/addon/toggle-autoplay/
Neither page has a feedback form or the author's contacts except for his nickname.

Unfortunately riiis has PMs disabled and has left no contact information in the profile.
