SeekParameters (ExoPlayer library)

java.lang.Object
- com.google.android.exoplayer2.SeekParameters

```
public final class SeekParameters
extends Object
```
Parameters that apply to seeking.
The predefined EXACT, CLOSEST_SYNC, PREVIOUS_SYNC and NEXT_SYNC parameters are suitable for most use cases. Seeking to sync points is typically faster but less accurate than exact seeking.
In the general case, an instance specifies a maximum tolerance before (toleranceBeforeUs) and after (toleranceAfterUs) a requested seek position (x). If one or more sync points falls within the window [x - toleranceBeforeUs, x + toleranceAfterUs] then the seek will be performed to the sync point within the window that's closest to x. If no sync point falls within the window then the seek will be performed to x - toleranceBeforeUs. Internally the player may need to seek to an earlier sync point and discard media until this position is reached.
