Use Taifun Files extension or Extension by @vknow360. You can not show video image in list view because the extensions available for extracting thumbnails is little bugged. 
which list i can take for showing videos by the device storage ?
You can use List View Image and Text but you can’t show thumbnails.
can i use grid view to showing device video?
You can use anything but you won’t be able to show the video thumbnail.
why?We have this extension:
I know. But it takes too much time to extract the thumbnail and show it in the listview.
The extension is good for extracting thumbnail from a single video but not from multiple videos at a time. I have tried every possible method but not getting the desired results.
It works a bit slow for online videos but not for local videos.
I would like to see your blocks.
How much time does it take?
Here you know the image component so why not use SetImage method?
I think for 20 videos, it takes around 20-25 seconds.
It is dynamic, so how can I use SetImage method? 
There is a method in my extension to set image’s picture asynchronously.
Oh yes, I tried that too but delay is same.
