Which quality level should the player start with? 0 = lowest, 4 = highest. The
default behavior is to start with the first quality rendition listed in the HLS manifest. Turning on
auto means the player will download the first segment of the lowest quality rendition and use that to test bandwidth. This however can slow down startup time because if it decides a higher quality is better, it will throw away the downloaded segment and start over at the first segment of the new quality.
What is the max quality level that should be used? 0 = lowset, 4 = highest. I believe this is similar to preferredPeakBitRate on iOS.
