Transmission optimization mode. Whether to prioritize video quality or smoothness:
"detail": Prioritizes video quality.
The SDK ensures high-quality images by automatically calculating a minimum bitrate based on the capturing resolution and frame rate. No matter how poor the network condition is, the sending bitrate will never be lower than the minimum value.
In most cases, the SDK does not reduce the sending resolution, but may reduce the frame rate.
"motion": Prioritizes video smoothness.
In poor network conditions, the SDK reduces the sending bitrate to minimize video freezes.
In most cases, the SDK does not reduce the frame rate, but may reduce the sending resolution.
Empty: Uses the default transmission optimization mode. The SDK may reduce the frame rate or the sending resolution in poor network conditions.
