Notes
Requires following Permissions on android
READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGELimitations
- Remote videos aren't supported on android sdk_version < 14.
- This is a Native Module, so it won't work in expo managed projects.
- This library heavily depends on the native API's to generate the thumbnails. Thus it can only generate from the video formats/codecs that are supported by the device's OS.
