Ffmpeg video to photos

I’ve found that FFmpeg is incredibly useful for handling various video operations. For instance, when I need to extract images from a video I’ve recorded, FFmpeg comes in handy. Sometimes, capturing the perfect photo can be tricky. It’s much easier for me to record a scene and then extract each frame from the video. This way, I can pick the best shots for social media or any other purpose.

Here’s how you can do it:

1. Install FFmpeg (if you haven’t already):
- On Windows, you can use Chocolatey, a package manager for Windows.
- Simply open a command prompt and run
choco install ffmpeg
2. Open a terminal or command prompt on your computer.

Run the following command to take a PNG screenshot every second from a WEBM file:
ffmpeg -i input.webm -vf "fps=1" screenshot_%04d.png
Explanation of the command:
  • -i input.webm: This specifies the input WEBM file. You can replace input.webm with your own video file, whether it's in MP4, MKV, or another format.
  • -vf "fps=1": This sets the frame rate to 1 frame per second. You can adjust the frame rate as needed.
  • screenshot_%04d.png: This is the output file pattern. %04d ensures that the screenshots are saved with a four-digit sequence number (e.g., screenshot_0001.png, screenshot_0002.png).

For more details on installing Chocolatey, you can visit the official installation page https://chocolatey.org/install.

Using this method, I’ve found it much easier to get the perfect photo from a video. I hope you find it helpful too!

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab.

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
