Carl, it's not a failing command line. It has nothing to do with that. It's a unsupported feature
Next time you report an unsupported feature that manifests itself when running FFmpeg with unsupported combinations of valid options (like in this case calling the e-ac3 encoder with seven channels) please provide the command line that does not produce the intended output together with the complete, uncut console output to make the ticket valid. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3755#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
