Video Scrubbing not working in Leanback Showcase #46

Open vkhirani93 opened 3 years ago

vkhirani93 commented 3 years ago

I cloned the repository and when I play video using ExoPlayer implementation, video scrubbing does not work at all. Instead it gives me a small yellow square as shown below.

Can anyone please help me here? I am new to Leanback & Android TV and couldn't figure it out at all.

It's not clear in the UI but the sample demonstrates different thumbnail providers for seeking; however, it uses placeholders by default. If you take a look at https://github.com/android/tv-samples/blob/main/LeanbackShowcase/app/src/main/java/androidx/leanback/leanbackshowcase/app/media/PlaybackSeekDiskDataProvider.java, you can see it's checking if a file is at that position otherwise falling back on a placeholder. The changes to file permissions make this not really a viable option, but seek thumbnails should also be provided via a server in most cases.
