I have a video file with messed up audio channels. When I play the video, the audio comes only from left speaker.
Here's media info
Both audio streams are messed up (on both, sound comes from left speaker only).
When I open the video in Sony Vegas for example, I see this (I removed the surround stream, don't need it)
In Sony Vegas I can easily fix for the sound to come from both speakers by choosing Combine or Left only. Both of this fix the audio
However, I want to do this with with ffmpeg.
I extracted the audio from the file with MeGUI.
I read this
and I tried ffmpeg with the following command
But I get an errorCode:ffmpeg -i audio.aac -filter_complex "[0:a]channelsplit=channel_layout=stereo:channels=FL[left]" -map "[left]" front_left.aac
I want to change the channel, without reencoding of the audio (is this possible?) and then just mux the audio and video.
Can anyone help me?
