FFmpeg on Qarnot Cloud - documentation

October 28, 2021 - 3D, Documentation


FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video.


FFmpeg versions adapted on Qarnot:

Release yearFFmpeg version

If you are interested in another version, you can select the one that you need on the Docker hub right here.

Test Case

In this test case, a mp4 file will be converted into an avi file. To download the demo file, create an input folder and navigate in it. There, use the following command: wget -O ./qarnot_computing.mp4

Launching the case

Before starting a calculation with the Python SDK, a few steps are required:

  • Please ensure that you have created a Qarnot account here.
  • Retrieve the authentication token here.
  • Install Qarnot’s Python SDK here.

Note: in addition to the Python SDK, Qarnot provides C# and Node.js SDKs and a Command Line. Once everything is set up, the following script needs to be used to start the calculation. Be sure you have copied your authentication token in the script (instead of <<<MY_SECRET_TOKEN>>>) to be able to launch the task on Qarnot. To use this script, simply copy the preceding code in a Python script, put it at the same level as the input folder. Your tree view should look like this:

  • input
    • qarnot_computing.mp4

 To launch this script, execute python3 & in your terminal.


At any given time, you can monitor the status of your task on Tasq.


Successful FFmpeg execution on Qarnot’s Tasq

You should now have an output folder in your working directory on your computer and a ffmpeg-out bucket on Qarnot’s Tasq containing the output avi video.

Wrapping up

That’s it! If you have any questions, please contact and we will help you with pleasure!
