Is it possible to have it so the fast forward and rewind go at a certain speed like 2x , 4x, and 8x depending on how many times you hit the button vs 30 second increments? I have converted my whole home to progtv Android for IPTV and that is the only feature that really keeps hanging me up. Much appreciated.

It is looks to complex on current step. For example I am do that only for ffmpeg and possible for mediacodec modes. But not many users use FFmpeg.
More possibility in Exo mode.

If you can do that with exo that would be a good work around. I have some of my streams using exo to deal with AC3 issues on some streams and it works pretty good. Other than the fast forward and rewind speed the app is fantastic you did an awesome job with it. Many thanks.
