通过互联网流媒体 - 喜欢VBR到CBR？ [英] Streaming over the Internet - Prefer VBR to CBR?

问题描述

您好！

当您通过互联网进行流媒体编码时，您应该更喜欢VBR到CBR（如果您的目标是获得最佳观看质量），这是否正确？ ，例如由于这里给出的理由：
http://en.wikipedia.org/wiki/Variable_bitrate

Is it correct that when you encode with the intent of streaming over the Internet you should prefer VBR to CBR (if you aim for the best viewing quality), e.g. due to the reasons given here: http://en.wikipedia.org/wiki/Variable_bitrate

CUDA加速仅适用于VBR是否正确？

Is it correct that CUDA accelleration only applies to VBR?

 

祝你好运，

推荐答案

VBR一般提供更好的压缩，因此对于相同数量的比特具有更好的质量，但通常不推荐用于流式传输，因为它可能导致跳跃或缓冲峰值。如果你为
流做VBR，我会确保使用约束，并为你的用户明智地选择最大比特率，以确保它不会发生。

VBR generally provides better compression, and thus better quality for the same amount of bits, but it's generally not recommended for streaming since it can result in skips or buffering on the peaks. I would make sure to use constrained if you do VBR for streaming and choose the max bitrate wisely for your users to ensure that it doesn't happen.

支持CUDA编码在CBR和VBR中。

CUDA encoding is supported in both CBR and VBR.
