# FFmpegDirectory

The `FFmpegDirectory` parameter sets the path to the FFmpeg libraries that are installed with HPE IDOL Speech Server. These libraries are required for the `wav` module to be able to accept a range of media files as input. If this parameter is not set, the `wav` module (and therefore most tasks) can only accept 16-bit, linear, PCM WAV files.

The installer sets the initial value of the `FFmpegDirectory` parameter during installation.

Type: | String
Default: | `install-directory/ffmpeg`
Required: | No
Configuration Section: | Paths
Example: | `FFmpegDirectory=C:\HewlettPackardEnterprise\SpeechServer\libraries`
