How to play local videos

[ElrB]

Hi, thanks for the elegant and robust work.
I am a bit struggling to play local videos. I have a video stored on device files at location e.g. file:///private/var/mobile/Containers/Data/Application/C05628FE-BDCD-45A6-B150-E60545458349/tmp/81A2D762-4481-40E8-B335-6F091544AE49.mov

I pass the url to DarkRoomCarouselVideoDataImpl then to DarkRoomCarouselData but video does not seem to play. I have the same video online and when I pass the online url, the video does start to stream.

Also, I see that the video progress/slider bar is jumpy upon updates, how could we perhaps smoothen the played progress. I am assuming there is a timer to get the updates, and need to decrease timer interval?

Please assist. Thanks.
