Hi Rutger, ----- Forwarded message from Rutger Helling ----- Date: Wed, 27 Dec 2017 04:52:26 -0500 (EST) From: Rutger Helling To: guix-commits@gnu.org Subject: 02/02: gnu: mpv: Update to 0.28.0. rhelling pushed a commit to branch master in repository guix. commit abc5ef5a7f7fecb99ca8213c0962f42cc1a65552 Author: Rutger Helling Date: Wed Dec 27 10:46:26 2017 +0100 gnu: mpv: Update to 0.28.0. * gnu/packages/video.scm (mpv): Update to 0.28.0. [inputs]: Change ffmpeg to ffmpeg-git, add wayland-protocols. ----- As a frequent user of mpv, I also noticed that its latest release requires this unreleased branch of FFmpeg (it will eventually be released as FFmpeg 3.5). I wonder, does mpv 0.28.0 bring some new features that make it worth it to build three copies of FFmpeg? There was already ffmpeg-2.8 and ffmpeg@3.4.1 (the latest upstream release). And, do we know if this copy of FFmpeg is ready to be deployed? If I remember correctly, FFmpeg is pretty expensive to build from source. But maybe it's no big deal, or the new features are worth it. Or maybe we should replace ffmpeg@3.4.1 with this unreleased development branch.
