====== ffmpeg - Video - Frame - Count number of frames ======

<code bash>
ffmpeg -i input.mp4 -map 0:v:0 -c copy -f null -
</code>

<WRAP info>
**NOTE:**  This loops through the video file but does not decode any frames.

  * It only increments the counter, thus it is very fast.

This works on any video file.
