FFmpeg

The plugin comes with ffmpeg-for-homebridge which ensures that the right FFmpeg is automatically installed for the system. It can happen that the installation fails. In this case read on below.

To check if ffmpeg is installed correctly and see a list of available commands try running the following command in the command line:

libfdk_aac (audio)

If you want to listen to audio from the cameras in HomeKit, it is important that FFMpeg is compiled with libfdk_aac.

ffmpeg-for-homebridge comes with this ecnoder. But if you still have problems with the encoder, on the following page I wrote down the most important steps to reinstall FFMpeg with the encoder.
