I'm available for discussion anytime, I got a little busy in the past days and I will busy the next 3 days, but I should be available today evening or now. I stated already what I think about the whole discussion in a blog post. To summarize it my take is quite simple, Libav leads the way regarding the main API, it offers a more compact surface for attacks if you are really concerned about security and usually it is a little more compact and a bit more tested over a wider range of architectures. I'm not for removing ffmpeg overnight since there are features that might be of use and I'm not so hypocrite to value diversity only when it is in favor of my interests. That said as long the two project are compatible having one or another as default is just a matter of making our life easier. I'm upstream for Libav and a good number of Libav developers are Gentoo users, including Gentoo on special platforms (e.g. aarch64). Few large projects such as VLC and Gstreamer switched to Libav as their default. Since Libav is the no-frills variant, notwithstanding the interesting campaign of "we have more security11ein!" less stuff should break since it is usually more tested and once we gather the samples triggering a crash usually we do not stop preventing that single crash but the whole class of possible defect (see my work on mov as an example). I cannot and will not say that Libav is perfect or that no bugs are introduced on our side and other outlandish statements, but within my biased point of view I would expect a better experience for the user not caring about which library to use. If you want to discuss on #gentoo-media ping me within 30 min or in 2 hours. I hope somebody not Libav nor FFmpeg committer could come up with a pros-cons list. lu
