Hi All, We noticed that if ffnpeg is built with avfoundation, we can read from an audio device on MacOS, but we cannot write to one.
Is there any way to coerce ffmpeg into writing to an audio device on MacOS mojave? We would like to have the audio from our videos sent into the MacOS coreaudio framework.
