https://www.ffmpegbyexample.com/examples/mb1erhnv/getting_streams_information_of_video_file/

By calling ffmpeg on a media file such as audio, video, or image without an output file - ffmpeg will list the different tracks on the media container, their encoding, and other relevant metadata.

Example output:

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4':
  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41
    encoder         : Lavf58.20.100
  Duration: 01:27:54.84, start: 0.000000, bitrate: 2666 kb/s
  Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 2530 kb/s, 25 fps, 25 tbr, 12800 tbn (default)
    Metadata:
      handler_name    : VideoHandler
      vendor_id       : [0][0][0][0]
  Stream #0:1[0x2](und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 128 kb/s (default)
    Metadata:
      handler_name    : SoundHandler
      vendor_id       : [0][0][0][0]

  At least one output file must be specified

In the example below Input #0 video.mp4 has 2 tracks, officially named Stream #0:0 and Stream #0:1.

The first stream (#0:0) is a video stream encoded in h264 encoding, has a pixel format of yuv420p and frame size of 1920x1080 SAR 1:1 DAR 16:9. The average video bit rate is 2530 kb/s (2.4 megabytes per second) and 25 frames per seconds.

The second stream (#0:1) is an audio stream encoded in aac stereo stream encoded at an average of 128 kb/s and sample rate of 44100 Hz.
