Updating EL-7 multimedia libraries

Hi there, This question was raised in a ticket, but would have been better raised in this mailing list for a better audience. I'm asking for opportunity to update at least the ffmpeg/x264/x265/live555/vlc, etc on EL7. It's questionable whether to keep "deep stable" libraries or to switch to newer ones on "deep stable" distros. Some EL users dislike newer versions and prefer known good (but secure) releases. On the others side, some others EL users rely on "deep stable" distros for most components, but when it comes to some (multimedia) activities, prefers newer components. (EL users that want newer components everywhere are fools and should better use Fedora). It seems hard to satisfy both sides at the same time. But at least something is possible. For example, we could introduce a new branch called el7-next that will relies on newer version of some components. most packages should be rebuilt for el7-next and superseed the one in the related el7 branches. I've not much time theses day for working on this on the infra side (not until July at least). But maybe it's already possible to collect ideas. Also it should be possible for someone to test build an updated stack. I would suggest the following: ffmpeg-3.3x (this version doesn't have the vdpau/vaapi breakage as found in ffmpeg-3.4 that may prevent some application to build). x264/x265/live555 current gsteamer1 needs EL7 matching libraries. The other way is probably to look at modularity, software collections or even copr dedicated repos... Any idea ? -- - Nicolas (kwizart)
