编码器中使用了fixed_frame_rate_flag的功能是什么? [英] What is fixed_frame_rate_flag used for in encoders?

问题描述

在编码器中有一个称为fixed_frame_rate_flag的标志.我尚未找到任何明确的解释，这是什么以及它的意义是什么.该标志可以设置为0或1，但是我不知道这意味着什么.

There is a flag called the fixed_frame_rate_flag used in encoders. I haven't been able to find any clear explanation of what this is, and what its significance is. The flag can either be set to 0 or 1, but I don't know what this would imply.

任何帮助，我们将不胜感激.

Any help, information would be appreciated.

推荐答案

固定帧速率与可变帧速率相反.如果视频是固定帧速率，则每个帧都有可预测的时间戳. timestamp = frame_number * frame_rate.如果其变量可变，则每个帧都有其自己的持续时间，并且某些帧显示的时间更长或更短，并且具有不可预测的时间戳.

Fixed frame rate is the opposite of variable frame rate. If a video is fixed frame rate, every frame has a predictable timestamp. timestamp = frame_number * frame_rate. If its variable, every frame has its own duration and some frames made displayed for longer or shorter periods and has an unpredictable time stamp.
