I am using exoplayer to play mp3 tracks. All good. If the track is completely buffered then in case of seek forward it does not reload as expected. However, in case of seek backward it reloads. How do i prevent that? Is it a bug in exo?
Not really a solution, but you can use a library that acts as a proxy between ExoPlayer and the video URL like AndroidVideoCache. It downloads the video to disk and supplies ExoPlayer with the local file URL so re-buffering is much faster.
