# 📺 Easy-FLV: Java RTSP/RTMP to FLV Converter
[![GitHub stars](https://img.shields.io/github/stars/javpower/easy-flv.svg)](https://github.com/javpower/easy-flv)
[![GitHub issues](https://img.shields.io/github/issues/javpower/easy-flv.svg)](https://github.com/javpower/easy-flv/issues)
[![Apache License 2.0](https://img.shields.io/badge/license-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
[![Java Version](https://img.shields.io/badge/java-1.8+-orange.svg)](https://adoptopenjdk.net/)
[![Spring Boot](https://img.shields.io/badge/spring--boot-2.7.+-blue.svg)](https://spring.io/projects/spring-boot)
## 🌟 About Easy-FLV
Easy-FLV is a Java library that converts RTSP or RTMP video streams into FLV format for playback in web browsers. It provides an efficient, stable, and easily integrable solution for real-time video monitoring, live streaming, and video stream processing.
### Why Choose Easy-FLV?
- **Efficient Conversion**: Quickly converts video streams to FLV format with no complex configuration required.
- **Easy Integration**: Used as a Spring Boot Starter, it can be easily integrated into any Java project.
- **Modern Browser Support**: Supports all major modern browsers without the need for additional plugins.
- **Real-time Stream Processing**: Suitable for the conversion of real-time video streams, such as security monitoring and live broadcasting.
## 📄 Screenshots
Below are screenshots of Easy-FLV in action:
![img_1.png](img_1.png)
![img.png](img.png)
## 🚀 Quick Start
### Add Maven Dependency
Include the following Maven dependency in your Spring Boot project:
```xml
<dependency>
<groupId>io.github.javpower</groupId>
<artifactId>rtsp-converter-flv-spring-boot-starter</artifactId>
<version>1.5.9.1</version>
</dependency>
```
### Implement Interface
Create a service class that implements the `IOpenFLVService` interface to provide the stream address:
```java
@Service
public class RtspDataService implements IOpenFLVService {
@Override
public String getUrl(Integer channel) {
// Retrieve the RTSP stream address based on the channel
return "rtsp://10.11.9.251:554/openUrl/16HV8mA";
}
}
```
### Configure YAML
Configure Easy-FLV in your `application.yml`:
```yaml
easy:
flv:
host: http://localhost:8200
```
### Use Interface
To get the converted stream address and play it in a browser:
- Conversion URL: `GET http://ip:port/get/flv/hls/stream_{channel}.flv`
- Direct Browser Playback: `GET http://ip:port/flv/hls/stream_{channel}.flv`
### Direct Usage
If you prefer not to implement an interface, you can directly encode the stream address and convert it:
```java
public static void main(String[] args) throws UnsupportedEncodingException {
String url = "rtsp://XXXXXXXX";
String encodedUrl = java.net.URLEncoder.encode(url, "UTF-8");
System.out.println("Encoded Stream URL: " + encodedUrl);
}
```
- Conversion URL: `GET http://ip:port/get/flv/hls/stream?url=EncodedAddress`
- Direct Browser Playback: `GET http://ip:port/flv/hls/stream?url=EncodedAddress`
## 🛠️ Contribution
Contributions of any kind are welcome, including but not limited to reporting bugs, submitting fixes, adding new features, and improving documentation.
## 📄 License
Easy-FLV is released under the [Apache License 2.0](LICENSE).
