Perhaps youtube-dl is forgetting to pass '-strict -2' ? Or its position is wrong?

Most likely outdated ffmpeg.

Adding --perfer-ffmpeg solved the problem, but this still seems like a bug?

No. As I've already said: outdated avconv/avconv bug.

NightMachinary · 2018-06-14T20:50:42Z

@dstftw I am using the latest libav available from Homebrew:

avconv -v                                       1 ↵  6783  01:16:41

What version will solve this problem, exactly? 🙄
