Improve ability to seek frame by frame forward and backward

Version

Media3 main branch

More version details

In my android application, user needs to identify the frame and then request for the process on the frame. When I pause the video and shift in frame backward or forward the behaviors is not correct. first time it always shifts frame to opposite direction.
Frame forward shift code:
val seekPositionForNewFrame = exoPlayer.currentPosition + ((1000 / fps))
exoplayer.seekTo(seekPositionForNewFrame)

Frame Backward shift code:
val seekPositionForNewFrame = exoPlayer.currentPosition - ((1000 / fps))
exoplayer.seekTo(seekPositionForNewFrame)

Mostly videos used are 60 fps.
