Configuring and using FFmpeg for MP3 audio recordings

note

FFmpeg is only needed if you require MP3 recordings.

The plugin will try to find the ffmpeg binary in the following order:

1. Command line argument -FFmpegPath=
2. Environment variable FFMPEG
3. Environment variable FFMPEG_PATH
4. Edit -> Project Settings -> Onset VoIP Settings -> Advanced -> FFmpeg Path

Go to:

Edit -> Project Settings -> Onset VoIP Settings -> Advanced -> FFmpeg Path

Set the path to the folder that contains the ffmpeg(.exe) binary.

This can be a relative or absolute path. To package your project with ffmpeg, set a relative path to your Content directory like in the image above.

Then add the ffmpeg folder to be included in your packaged build under:

Edit -> Project Settings -> Project -> Packaging -> Additional Non-Asset Directories To Copy

If you only require ffmpeg for recording on dedicated servers, you can use:

Additional Non-Asset Directories To Copy for dedicated server only

After setup, audio recording supports MP3.

There is also another node to convert any audio file to another codec.
