For example, u-law,a-law Channels – How many channels are contained in the audio data.  For example, Stereo 2 channels SoX supports over 20 audio file formats.

How to get video or audio duration of a file using ffmpeg?

-
Today we will learn How to get the duration of a file using ffmpeg 1. Format Container Duration - [This works for both Video and Audio Files - better to report numbers using this command] ffprobe -v error -show_entries format=duration \ -of default=noprint_wrappers=1:nokey=1 input.mp4     2. Video Stream Duration - [This works only for Videos]   ffprobe -v error -select_streams v:0 -show_entries stream=duration \ -of default=noprint_wrappers=1:nokey=1 input.mp4     Content author - https://superuser.com/questions/650291/how-to-get-video-duration-in-seconds
