-    # Input: arg1: input file path
-    # Output: stdout (if valid audio format)
-    #         exit code 0 if audio file; 1 otherwise
-    # Example: get_audio_format myvideo.mp4
-    #   Note: Would return "opus" if full ffprobe report had 'Audio: opus, 48000 Hz, stereo, fltp'
-    # Note: Not tested with videos containing multiple video streams
