问题描述

我正在使用以下命令从给定的视频和图像生成视频，我也在填充和缩放视频.该命令效果很好，并且可以产生预期的结果，但是在生成的视频中没有声音！

I'm using the following command to generate a video from a given video and an image, I'm also pading and scaling the video. This command works great and it generates the expected result, However in the resulted video there is no sound!

ffmpeg.exe -i input.mp4 -i rj2k15y3.png -filter_complex "[0:v]scale=440:440,setsar=1:1,pad=640:640:(ow-iw)/2:120:color=white[padded]; [padded]overlay=0:0[out]" -map "[out]" -y -metadata title="video1" result.mp4

推荐答案

自从创建了map语句以来，只有明确映射的流才被复用到输出中.

Since a map statement is made, only expressly mapped streams are muxed into the output.

更改为 ... [padded] overlay = 0:0"-y ... 或添加 -map 0:a
