Mute a channel. This example uses the pan audio filter to mute the first channel (front left) but keep the second channel (front right) as is: ffmpeg -i stereo.wav -af "pan=stereo|c1=c1" output.wav. Example using the -map_channel option: ffmpeg -i stereo.wav -map_channel -1 -map_channel 0.0.1 output.wav.This option has been removed from FFmpeg a while ago. This means you are using an outdated build. Use the -crf option instead when encoding with libx264. This is the H.264 video encoder used by ffmepg and, if available, is the default encoder for MP4 output. See the FFmpeg H.264 Video Encoding Guide for more info on that.

Another option is compressing the audio without touching the video, as some audio streams can be larger than needed (256kb/s AAC can go down to 128 or 96 depending on how important it is). Just a note: you can totally have lossless compression.

By default ffmpeg attempts to read the input (s) as fast as possible. This option will slow down the reading of the input (s) to the native frame rate of the input (s). It is useful for real-time output (e.g. live streaming). My doubt is basically the part of the above description that I highlighted. It is suggested to not use the option during ...

Fast encoding example: ffmpeg -i input -c:v libx264 -preset ultrafast -qp 0 output.mkv. Best compression example: ffmpeg -i input -c:v libx264 -preset veryslow -qp 0 output.mkv.

Enter the conversion command. The conversion command starts with ffmpeg -i and then includes your file's current name and file type as well as whatever you want the converted file name and file type to be. For example, to convert an MP4 video called "Kitties" into a WAV file called "Cats", you would type in ffmpeg -i Kitties.mp4 Cats.wav here. CRF stands for Constant Rate Factor. Quote from ffmpeg docs: "The range of the CRF scale is 0–51, where 0 is lossless, 23 is the default, and 51 is worst quality possible. A lower value generally leads to higher quality, and a subjectively sane range is 17–28. Consider 17 or 18 to be visually lossless or nearly so." FFmpeg can play video and audio files of different formats in RetroArch. If a video file has more than one audio input, FFmpeg can switch between them.
