Hi there, will adding and using this

<https://news.opensuse.org/2023/01/24/opensuse-simplifies-codec-install/>

for 15.4 help my opensuse 15.4 firefox to surf twitter and see animations aka videos on twitter? multimedia on opensuse is bascially restricted to ancient mp3 and youtube.com for me using firefox and default stuff from opensuse 15.4 youtube being very generous when offering users a fallback codec for noncopyrighted or nonpatented codec layers and encoding stuff with that and delivering it to the user. I added this specialty cisco patent stuff codec repo from that news post url up there but twitter is still nonvideo for me. what am i doing wrong? or is this news just a very basic first step or something? i am not very literate in this kind of stuff. also i fail to see the real connection with this special area called packman repos for opensuse and who are the people behind running that packman stuff and why they dont have trouble with legal or patents but opensuse as a project does etc tia
