We can implement seek data provider in our android application. So when user seeks the video progress bar, he/she will see thumbnails of video just above the progress bar. (like youtube player!)
There is ways to implement this feature on server side to get some jpeg images along video and show them as user seeks. But if there is not such feature in the server, can we (at android client) extract some thumbnails (say every 1 second) to show as seek data as we get and buffer video for playing?
Is there an android library for this? (specially related to exo player which android devs use!)
