I forgot the error information from Firefox. It is

There was an issue during media playback with the content that was playing. The sub-error code will contain additional information about the underlying cause. | NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error no decoder found for video/avc

Make sure you have the latest FFmpeg and libavcodec packages installed.

After the video stopped working I reinstalled the codecs using those from the packman repo. I assume they are the newest ones. Maybe I missed the libdvdcss repo.

I am not at that computer, I am using my home computer where I did not install the newest Firefox. Tomorrow I will check the libdvdcss repo.

Examples of the video(s) not working would be nice. Have you ever tried this site? https://www.opensuse-community.org/ Are you on Leap or Tumbleweed? X11 or Wayland? What desktop?

jonzn4SUSE,

Thank you for answering.

1) I tried several videos on cnn.com. None of them worked. All gave the same message as above. On Amazon I tried Jack Ryan, season 1, episode 7 with the same result.

2) After the failure I used a set of command line commands to reinstall the codecs and switch them to packman. After that Chrome worked for playing the videos.

3) I am using Leap 15.4 with KDE. No guarantee, but I think it is X11. Some of the hardware: Nvidia GTX 1050, AMD 3600, and 16 GB DDR4 ram.

4) I also checked the OPENSUSE forums and did not find any posts about this problem.

I will try reinstalling the codecs again tomorrow.

jonzn4SUSE,

Thank you for answering.

1) I tried several video segments from CNN and Jack Ryan, season 1, episode 7 from Amazon. All gave the same error as above.

2) I used a set of command line commands to change all of the codecs to packman. Chrome ran the videos with no errors.

3) I am using Leap 15.4 with KDE, and, I believe, X11. Some of the hardware Ryzen 5 3600, Nvidia GTX 1050, and 16 gb of DDR4 ram.

4) I checked the openSUSE forum and did not find this problem there.

I will try a cold start tomorrow to see if that helps.

I have an older laptop running 15.4. Let me get on it and see what happens. Do you have the same issues with Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode

No issues for me on 15.4. see screenshot

I tried the link you sent. It did not work. It is now working after using YAST to switch the codecs to packman manually.

Thank you for your help and patience.

I would try a VM and see if you have the same issue. It could be another app you have installed causing the issue. I have 5 laptops, 4 running Tumbleweed and 1 running 15.4 and have no video issues.

It could be, but I have too much junk on the computer to track it down now. Thank you for the help.
