Thank you for your consideration. I have re-arranged the ffmpeg package basend on Fedora's ffmpeg-free package. https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg/ > If you don't think the package is useful under those constraints, don't > let this discourage you from offering either the cygport for interested > people to build it themselves, or the packages via an overlay package > server [2] As I mentioned in IRC, the Fedora approved numerous of codecs for ffmpeg recently. As a result, ffmpeg-free package becomes much more useful compared to the past. As far as using for ffmpeg-plugin of moc (Music player), it has almost enough codecs. ffmpeg itself might be somewhat weak (e.g., no x264, x265), however, it whold be much better than nothing. > [1] https://cygwin.com/packaging-contributors-guide.html#submitting > [2] https://cygwin.com/package-server.html#overlay -- Takashi Yano <takashi.y...@nifty.ne.jp>
