"It doesn't work" should kindly be amended with the actual error message. ffmpeg outputs a lot of useful information, and we usually ask you to provide the full, uncut console output.

If you're compiling on your own anyway, why didn't you compile git master? That's what the docs deployed on ffmpeg.org refer to (which they unfortunately don't explicitly say, I think). *Your* official - the ones valid for your particular version - are in your source package, or in your installation under $prefixshare/doc/ffmpeg/. What I'm trying to hint at: Those options where added to git master after the release of ffmpeg 3.1 (and not backported to 3.1.1), and will therefore likely not be in an ffmpeg release before 3.2. Checking your local docs will confirm that. You need to build from git master is the summary of my answer. ;) Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
