RCCallVideoBitrateMode enum
Values
- cq → const RCCallVideoBitrateMode
-
ZHConstant quality mode
完全不控制码率，尽最大可能保证图像质量； 质量要求高、带宽足够、解码器支持码率剧烈波动的情况下，可以选择 CQ 码率控制策略。
ENConstant quality mode
Maximizes image quality without bitrate control Ideal when quality matters, bandwidth is sufficient, and the decoder handles bitrate fluctuations
- vbr → const RCCallVideoBitrateMode
-
ZHVariable bitrate mode
码率可以随着图像的复杂程度的不同而变化，因此其编码效率比较高，马赛克很少。适合的应用场景是媒体存储，而不是网络传输； VBR 输出码率会在一定范围内波动，对于小幅晃动，方块效应会有所改善，但对剧烈晃动仍无能为力；连续调低码率则会导致码率急剧下降，如果无法接受这个问题，那 VBR 就不是好的选择。
ENVariable bitrate mode
Bitrate adjusts to image complexity for higher encoding efficiency with minimal artifacts. Best for media storage, not streaming. VBR bitrate fluctuates within a range—reduces blocking for minor motion but struggles with rapid movement. Consistently lowering bitrate may cause sharp drops. Avoid VBR if this is unacceptable.
- cbr → const RCCallVideoBitrateMode
-
ZHConstant bitrate mode
码率在流的进行过程中基本保持恒定并且接近目标码率，当对复杂内容编码时质量会下降。在流式播放方案中使用CBR编码最为有效 CBR 的优点是稳定可控，这样对实时性的保证有帮助.
ENConstant bitrate mode
Maintains steady bitrate close to target, though complex content may reduce quality. Best for streaming CBR ensures stable performance for real-time needs
