====== ffprobe - Duration ======

===== Container Format Duration =====

<code bash>
ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 input.mp4
</code>

returns:

<code>
30.024000
</code>

<WRAP info>
**NOTE:**  The output duration is in seconds.

Adding the **-sexagesimal** option will use the HOURS:MM:SS.MICROSECONDS time unit format:

<code>
0:00:30.024000
</code>

</WRAP>

----

===== Stream duration =====

Duration of the first video stream:

<code bash>
ffprobe -v error -select_streams v:0 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1 input.mp4
</code>

returns:

<code>
30.000000
</code>

<WRAP info>
**NOTE:**  Not all formats, such as Matroska and WebM, store duration at the stream level resulting in duration=N/A.

  * Refer to Format (container) duration instead.

----

===== Get duration by decoding =====

Get the duration by fully decoding the file.

  * The null muxer is used so no output file is created.

<code bash>
ffmpeg -i input.mkv -f null -
</code>

returns:

<code>
...
frame=206723 fps=1390 q=-0.0 Lsize=N/A time=00:57:28.87 bitrate=N/A speed=23.2x
</code>

<WRAP info>
**NOTE:**  This will report the correct duration in case the methods shown above using ffprobe are incorrect or missing due to corrupt, truncated, or damaged files.

  * **time=** - in the next-to-last line of the console output has the duration.
    * In this example the input has a duration of 00:57:28.87.

  * The command may take some time depending on the input file duration and decoding complexity.
