I am using Vitamio Library in my app. But the problem is, while playing when i try to move seek bar forward or backward the progress bar is in accurate.
I debug the code and found that, in setProgress() method in MediaController class:
long position = mPlayer.getCurrentPosition();
this position is always same. I am not getting that why getCurrentPosition() is always returning same value.
I also search it on Vitamio website and i found:
https://www.vitamio.org/en/docs/FAQ/2013/0509/6.html
When I drag the seekBar, Why the progress bar is inaccurate?
It's all right, this isn't Vitamio's bug, because you must drag the seekBar to the key frame, But the key frame is not always on every timestamp, except you use the intra-only encoding.
What does this mean? and how can i fix it. Please help me.
In Vitamio When I drag the seekBar, the progress bar is inaccurate? How to fix it?
I just wanted to tell you all that I had made a custom solution to fix this issue. You can take help from this solution If you still facing this issue. I have made changes in MediaController.java class in library. You just need to replace this class from your previous class and then run your code.
