问题描述

我正在使用 ffmpeg 连接三个视频.但是，由于某些原因，我遇到了错误.

I am concatenating three videos using ffmpeg. However, for some reasons I am getting error.

我使用的是 NReco Video Converter，它是一个 FFMpeg C# 包装器.

I am using NReco Video Converter which is a FFMpeg C# wrapper .

任何帮助将不胜感激.

以下是我完整的控制台输出:

推荐答案

正如您从控制台输出中看到的，问题是三个输入具有不同的 SAR 值:0:1 表示第二个第一个和第三个输入的输入 vs 40:33.

As you can see from the console output the issue is that the three inputs have different SAR values: 0:1 for the second input vs 40:33 for the first and third inputs.

您可以使用 setsar 过滤器设置正确的 SAR 值，例如:

You can set the corect SAR value using the setsar filter, eg:

 [1:v:0]setsar=sar=40/33[1v0sar]

然后将 [1v0sar] 与其他视频流一起传递给 concat 过滤器.

then pass [1v0sar] to the concat filter along with the other video streams.
