Sets the lower limit of the interval range for the adaptive adjustment of the stream playing cache of the stream mixing server. In the real-time chorus KTV scenario, slight fluctuations in the network at the push end may cause the mixed stream to freeze. At this time, when the audience pulls the mixed stream, there is a high probability of the problem of freeze. By adjusting the lower limit of the interval range for the adaptive adjustment of the stream playing cache of the stream mixing server, it can optimize the freezing problem that occurs when playing mixing streams at the player end, but it will increase the delay. It is not set by default, that is, the server uses its own configuration values. It only takes effect for the new input stream setting, and does not take effect for the input stream that has already started mixing.Value Range: [0,10000], exceeding the maximum value will result in a failure of the stream mixing request. On web platforms, this property does not take effect.

If you want better video quality, lower the quality value based on 23 to test the adjustment. If you want a smaller file size, test the adjustment by increasing the high quality value at the base of 23. Take the file size under the value x as an example. The file size under the value x + 6 is half the size of the file size under the value x, and the file size under the value x-6 is twice the size of the file size under the value x.
