====== ffprobe - Streams - Get the number of available streams ======

<code bash>
ffprobe <input> -show_entries format=nb_streams -v 0 -of csv=p=0

or 

ffprobe <input> -show_entries format=nb_streams -v 0 -of compact=p=0:nk=1
</code>

<WRAP info>
**NOTE:** This can be filtered for only video or audio streams by adding **-select_streams v** or **-select_streams a**, respectively.

  * **-v 0** only show fatal errors which could lead the process to crash, such as an assertion failure. 
    * This hides "info" output (version info, etc) which makes parsing easier.
  * **-show_entries format=nb_streams** shows the number of streams.
  * **-of csv=p=0** sets the output formatting. In this case it hides the descriptions and only shows the value. 
    * See [[https://ffmpeg.org/ffprobe.html#Writers|FFprobe Writers]] for info on other formats including JSON.
