Hi,
Doing the multimedia guide suggested, I get
Problem: libavformat58-4.1.3-5.4.x86_64 requires libavcodec58 = 4.1.3-5.4, but this requirement cannot be provided
What is the suggested solution to this message?
Hi, welcome to these forums !!!
Please show
zypper lr -d
. You need a vendor switch to the Packman repo.
Thanks!
Wow, that was fast …
The result is:
linux-q155:~ # zypper lr -d

In your first post, you posted the message, but not how you got that.
You repos look OK, but you should disable #2, that is the installation medium and when you leave that on, the system will ask for it every time you start softwar management.
And the you should od the Vendor switch like Knurpht says:
zypper dup --from packman
When you get the same (or any other) problem, please post here (complete including prompt-command line) for more help.
You might want to make that
sudo zypper dup --from packman --allow-vendor-change
Correct, I forgot the default on Tumbleweed is different. 
Thanks, that solved several issue with one reply (that is with the correct invocation of)
sudo zypper dup --from packman --allow-vendor-change
