Hi Moritz, I have given below the output in plain text. I also tried adding a USB external microphone which is working great in multiple apple apps but ffmpeg does not seem to recognize and the output is the same as shown below. I also wonder if my command is correct, as in Linix/Windows the command line to record from webcam explicitly includes Audio and Video streams inputs but in OSX the command I am using does not seem to include audio input explicitly.
Example: In Windows you explicitly identify video and audio inputs as shown below and this world great. >ffmpeg –f dshow –i video=”USB2.0 Camera”:audio=”Microphone (Realtek High >Definition Audio)” out.mp4 (Windows command line) How to do the same in OSX?
