DEGRADATION_PREFERENCE

Video degradation preferences when the bandwidth is a constraint.

Enumerator

MAINTAIN_QUALITY

0: (Default) Prefers to reduce the video frame rate while maintaining video resolution during video encoding under limited bandwidth. This degradation preference is suitable for scenarios where video quality is prioritized.

MAINTAIN_FRAMERATE
1: Reduces the video resolution while maintaining the video frame rate during video encoding under limited bandwidth. This degradation preference is suitable for scenarios where smoothness is prioritized and video quality is allowed to be reduced.
MAINTAIN_BALANCED

2: Reduces the video frame rate and video resolution simultaneously during video encoding under limited bandwidth. The MAINTAIN_BALANCED has a lower reduction than MAINTAIN_QUALITY and MAINTAIN_FRAMERATE, and this preference is suitable for scenarios where both smoothness and video quality are a priority.

Attention: The resolution of the video sent may change, so remote users need to handle this issue. See OnVideoSizeChanged.
MAINTAIN_RESOLUTION
3: Reduces the video frame rate while maintaining the video resolution during video encoding under limited bandwidth. This degradation preference is suitable for scenarios where video quality is prioritized.
