Hi! We are new users of ArcGIS FMV. We’ve program a Python toolbox that is using the Video Multiplexer to automate our workflow. Our input videos (mp4) contain sound. However, every multiplexed output videos don't have sound. Is this the expected behavior of the tool or there is an option somewhere? We really need to keep audio data in the videos. I’m using ArcGIS 10.4.1 with FMV 1.3.1. Thanks!
