问题描述

我必须对ffmpeg使用以下命令

I have to use the following command for ffmpeg

ffmpeg -i "Video.mp4" -map 0:1 "AudioWithVocalfromStreamOne.mp3" -map 0:2 "AudioWithoutVocalfromStreamTwo.mp3"

我已经在Mac上成功安装了ffmpeg.我尝试使用 FFMPEGWrapper ，但是使用地图"似乎没有任何此类参数.

I have successfully installed ffmpeg on my mac. I tried using FFMPEGWrapper, but it doesn't seem to take any such parameters for using "map".

我需要知道如何从视频中提取流.我已经可以访问流了，因为服务器端在端使用ffprobe向我提供了这些流.

I need to know how to extract the streams from a video. I already have access to the streams, as server side is providing it to me using ffprobe at their end.
