Video soud is too loud

I have a layouts where main stream is rtsp, and time to time appear ad. Ad is video file. But I have issue with video sound it very loud. How can i make less sound of video ?

There is no volume control on Xibo players other than the webOS one.

You can only either have the sound or mute it.

Perhaps the volume can be adjusted on the audio system that you’re using to ensure that it is fine for both stream (if it has audio) and your videos?

Alternatively you can re-encode your video and lower the audio gain.
