The volume would change smoothly.

What actually happened?
As I was sliding the volume slider up, the volume jumped up, then back down and then up again a few times.

At first I thought this may be an issue with my app/volume slider, but I tried it on the Shaka player Demo page and was able to reproduce the problem.

I attached a video of the the issue on the Shaka player Demo page.

The issue is not that prominent on the Shaka player Demo page as the volume slider is very small and doesn't display the volume number.
It's much more noticeable when using a large volume slider which displays the number.

There is a similar issue with seeking and the timecode that we've already solved. The solution for volume should be similar. When the user is in the middle of changes, we should display and format for what the user has input, not what we're getting as feedback from the remote device (which may lag).
