Identifying Video with Multiple Audio Tracks

[bigcarp22]

I have several home videos that for some reason have multiple audio tracks and cause audio echo issues during playback on my Apple TV. I have found that I can re-encode the files using Handbrake and remove the offending audio track which solves the problem.

My issues is this: I have over 300 video files in my collection and not all of them have the multiple audio track issue. Is there a way I can list all my video files and identify which ones have multiple audio tracks, then I will know which ones to go in and fix. Or some other clever way to know which of my video files have more than one audio track?

You don't need to re-encode to get rid of unwanted audio channels, you just need to re-mux (lossless).
if you do this with ffmpeg it only keeps the first audio by default.

To identify all files with multiple audio: maybe it's possible using mediainfo ?

with MediaInfo CLI:
