Sound ok, but video looks low quality and image changes only every 5-10 seconds

Hello,

OSMC 2024.08-1
on a raspi4 4 GB.

Arte+7 seems to work quite well (good quality sound&video).

RTS Play TV has good sound, but video quality and it's a bit like a slide-show (the image changes only every 5-10 seconds).
Changing the option about HD quality does not change anything.
Plugin version: 2.2.4

Do you have an idea? What should I try?

Thank you.

This only happened with the very latest Telejournal. Did not happen with the other broadcasts or older version of the Telejournal. Maybe there is something funny with the "live" version.

Unfortunately, I have no idea what the issue could be. I couldn't reproduce this issue. It somewhat sounds like your Pi could be overloaded, but honestly, I don't really have a clue. Does the issue still persist?

Thank your for trying to reproduce it. I will also try on another raspi4, and maybe with different versions of kodi and OSMC. Have a nice day.

I think I have located the issue: some of the RTS play media are protected through a proprietary codec. For those media, the first time, WineCDM is loaded automatically. However, then, when playing, you get the "slide show" effect: sound is ok, but the image only changes every 5-10 seconds. For example, on RTS, "Les enquêtes de Murdoch" seem to be protected. I guess you don't do anything about it and the issue is really the kodi video playback using WineCDM? Searching for this specific issue did not bring much, I am struggling for what keyword to use for "video does not play like a stream, but only get one image, which sticks for 5-10 seconds, then another image". Maybe it's MPEG and we only get to see the I (complete) image, and the P and B images don't get decoded? Have a nice night.

Thanks for mentioning a video. I have tried it and can confirm the issue (even on my PC, so it is definitely not a Pi issue). It only appears when playing a DRM protected video. I know that is used to work correctly when I first implemented it, although the video quality was always quite low (resolution-wise), but it definitely didn't have this slide-show effect. I'm not sure if the problem is a plugin issue or it is more a issue of Kodi itself.

I have opened an issue for this problem: goggle/script.module.srgssr#30
