Hi,
I have a few mp4 videos where (with headphones) the left eared audio needs to be removed, but I want to keep the right eared audio. On mediainfo it says there is one audio stream, but 2 channels. Here is some info:
Audio
ID : 2
Format : AAC
Format/Info : Advanced Audio Codec
Format profile : LC
Codec ID : mp4a-40-2
Duration : 1 h 24 min
Bit rate mode : Constant
Bit rate : 128 kb/s
Channel(s) : 2 channels
Channel positions : Front: L R
Is there a solution to this? Would have thought the fix is relatively simple but searching online I cannot find one. As you may have guessed, I am not a particulary technical person.
Thanks very much for your help, and if there is more information required please say so.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

With one video and stereo audio you could try
Code:ffmpeg -i video.mp4 -c:v copy -filter_complex "[0:a]channelsplit=channel_layout=stereo:channels=FR[right]" -map "[right]" -map 0:0 One_track.mp4

1. Extract audio and convert to PCM WAV audio: the free AOA AudioExtractor
2. Remove the one channel followed by turning the remaining one to dual mono followed by saving as AAC audio: the free Audacity
3. Replace original audio with the new one: the free MP4Box with a GUI -

@Lol
This is a Command Line Interface (CLI) command.
You should have ffmpeg in your path or type the path before ffmpeg.
You open a command prompt and paste in the command.
