I didn’t add the input stream as I am not sure what stream it is on your source. If could be something like… ffmpeg -stats -y -i Original.mkv -filter_complex "[0:1]channelsplit=channel_layout=7.1:channels=LF|RF[lf][rf];[lf][rf]amerge=inputs=2[aout]" -map 0:v -map "aout" -map 0:s channel_split.mkv _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
