audio mapping in ffmpeg -


i have video file audio in 1 channel, left.

i'd use ffmpeg -map_channel option map audio appears in both l&r channels.

what ffmpeg command like?

ffmpeg -i input.mov -c:v copy -c:a copy -map_channel 0.1.0 -map_channel 0.1.0 output.mov

isn't working. audio still in left channel only.

remove -c:a copy. -map_channel way of using pan filter, can't stream copy (-c:a copy) , filter @ same time.

if want use pan instead:

ffmpeg -i input -filter_complex "pan=stereo|fl=c0:fr=c0" -c:v copy output
