有什么方式可以互换视频的左右声道？

Switch stereo channels

Switch left channel to right and right channel to left with the channelmap audio filter:

1. ffmpeg -i stereo.mp3 -filter_complex "channelmap=map=FL-FR|FR-FL:channel_layout=stereo" output.mp3

复制代码

Or with the pan audio filer:

1. ffmpeg -i stereo.ogg -af pan=stereo|c0=c1|c1=c0 output.wav

复制代码

or with -map_channel:

1. ffmpeg -i stereo.ogg -map_channel 0.0.1 -map_channel 0.0.0 output.wav
