Hi Andrea, The ffmpeg version I was using did not have this problem, (ffmpeg-20160517-git-af3e944-win64-shared) but after updating to ffmpeg-4.0 I could hear and see the problem as well. I've tried ffmpeg versions 3.4.2 and 3.2 as well - still problems, found a binary version of 3.0 here <https://bitbucket.org/sage2/binaries/downloads/> (build 2016-02-08) - that works. I don't have a build setup for ffmpeg yet, so I can't dig down to the actual problem, but I hope finding a working version helps you along.
