react-native-video-processing: Problem with source, no view loaded.

I’m trying the usage example from readme, i use

<VideoPlayer
....
source={{ uri: this.props.uri }}
....
/>

and also for Trimmer

<Trimmer
....
source={{ uri: this.props.uri }}
....
/>

but, i got warning ‘Failed prop type: Invalid prop source supplied to VideoPlayer’ and no view loaded, also same for Trimmer . i got this in ios and android. did i miss something ?

then i’m trying using source={require('./video.mp4')} no error and no view loaded.

if you don’t mind, would you add an example ?

thx
