Created attachment 1780 [details] youtube test Took me way longer than I want to admit to realize that I could just download the chromium SRPM and copy the spec into the extracted folder in order to easily acquire all the patches. It works great, and passed the "youtube test" https://www.youtube.com/html5 with flying colors!

It overrid the chromium-libs-media package as it was supposed to and worked out of the box after that. Well done mystery SPEC updater. Definitely promising results.
