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)

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You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.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)
