Some video content can not be displayed.
I use a laptop with Fedora 36 installed. Firefox is version 104.0.1
Until a few days ago, there were no problems with video display. But since a few days, video content that is offered by the news site from NOS (Dutch television) is not displayed anymore. I only get this error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support.
Also some content on Youtube aborts. For example loading https://www.youtube.com/watch?v=qq0BUiEs3JM results in this error: Er is een fout opgetreden. Probeer het later opnieuw. (Afspeel-ID: Ui0fzPxdSexgYcZ4).' (An error occured, try later again).
When using the Chrome Browser both websites can be used without giving errors implying that all the codecs are available.
How can I detect why video is blocked?
(Twitter also gives problems. After a fraction of a second, it stops displaying video)

After a reboot everything seems to be working. I don't know if it was the reboot or the removal of libwscale or libresample which solved the problem.

You can check the Web Console for media related messages.
Make sure you have the latest FFmpeg and libavcodec packages installed.
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages about blocked content.

You can try these steps in case of issues with webpages:
You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.
- hold down the Shift key and left-click the Reload button
- press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
- press "Command + Shift + R" (Mac)
Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).
"Remove the Cookies" for websites that cause problems:
- Settings -> Privacy & Security
Cookies and Site Data: "Manage Data"
"Clear the Cache":
- Settings -> Privacy & Security
Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

- https://support.mozilla.org/en-US/kb/how-clear-firefox-cache
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
Hi,
Attempts to (re)install ffmpeg and libavcodec resulted in errors. After adding --allowerasing and --skip-broken to the command I got the following output:
> sudo dnf install ffmpeg libavcodec-free --allowerasing --skip-broken Laatste metadata-expiratie-check: 0:02:04 geleden op di 13 sep 2022 12:27:48 CEST. Pakket libavcodec-free-5.0.1-11.fc36.x86_64 is al geïnstalleerd. Afhankelijkheden opgelost.
Probleem: pakket ffmpeg-libs-5.0.1-3.fc36.x86_64 conflicteert met libavcodec-free aangeboden door libavcodec-free-5.0.1-11.fc36.x86_64

After removing libswscale-free, the next attempt to install ffmpeg learned me that there were conflicts with libswresample. After removing libswresample, I was able to reinstall ffmpeg but I still cannot install libavcodec, due to conflicts with ffmpeg-libs.
I also tried to reinstall libswscale and libswresample but both installs tried to remove ffmpeg, ffmpwg-libs and libavdevice. > sudo dnf install libswscale-free-devel --allowerasing Laatste metadata-expiratie-check: 0:34:56 geleden op di 13 sep 2022 12:35:20 CEST. Afhankelijkheden opgelost.

What is the best way to resolve the conflicts (and reinstall libswscale and libswresample)
Ben
