FFmpeg is a command line tool that offers a lot of options to manipulate video and audio files. In this post I will show you how to compress a video file using it.
We usually use FFmpeg in a terminal, there are also graphical interfaces that use it as a backend. For example, HandBrake is a graphical interface that uses FFmpeg to compress video files. But in this post we will use FFmpeg directly.
Some days ago, I tried to use the onboard temperature sensor of the Raspberry Pi Pico using Arduino, but I only found tutorials for MicroPython. Affortunately, I found a Github issue where someone answered how to do it. So, I decided to create a library based on that code and I want to share it with you. The issue is here.
Consider giving a star to the repository if you find it useful. You can find it here.
In this article we’ll learn how to create a function for copying text to the clipboard. The method for managing context in the application is slightly different.
The app I’m using for this example is a password manager where I need to copy to clipboard the text from the text field. You can find the project on my Github at this link: https://github.com/DeimosHall/Glocker.git. However, you can follow the steps in your own app.
If you want to cut a video but you don’t want to open a video editor, you can use a terminal utility called “ffmpeg”.
On Debian/Ubuntu based systems we can install it with:
sudo apt install ffmpeg
Now we can use the following command to cut a video:
ffmpeg -i input.mp4 -ss 01:29:23 -to 01:35:02 -c copy output.mp4
With “ffmpeg -i input.mp4” we say we want to use the video called “input.mp4”. It’s important to use the mp4 file extension.
