Yes! Thats the lovely sound that comes out of all the videos that I have.
So supposedly theres time (and navigation) embedded in the audio? I've also
attached a sample of the file that I am working with. I was using ffmpeg in
terminal to try to extract the start time of the video.
timecode : 00:00:00;00
Duration: 00:01:16.51, start: 0.000000, bitrate: 124294 kb/s
Stream #0:0: Video: rawvideo (Y41B / 0x42313459), yuv411p, 720x480, SAR
8:9 DAR 4:3, 29.97 tbr, 29.97 tbn, 29.97 tbc
Stream #0:1: Audio: mp3 (U / 0x0055), 32000 Hz, stereo, s16p,
But it just shows timecode: 00:00:00;00 instead of an actual time that I'm
