Field description: whether to "ensure definition" or "ensure smoothness" on a weak network

Note

- Smoothness is ensured on a weak network, i.e., the video image will have a lot of blurs but can be smooth with no lagging.
- Definition is ensured on a weak network, i.e., the image will be as clear as possible but tend to lag.

## Implementation

    int preference;
