以下是Java中使用FFmpeg将视频转换为H.264编码流输出到指定文件夹的示例代码:
```java
import java.io.IOException;
public class VideoConverter {
public static void main(String[] args) {
String inputFilePath = "path/to/input/file.mp4";
String outputFolderPath = "path/to/output/folder/";
String outputFileName = "output.h264";
// build the ffmpeg command
String[] cmd = {
"ffmpeg",
"-i", inputFilePath,
"-c:v", "libx264",
"-preset", "ultrafast",
"-f", "h264",
outputFolderPath + outputFileName
};
// execute the ffmpeg command
try {
Process process = new ProcessBuilder(cmd).start();
process.waitFor();
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}
}
}
```
请注意,此示例假定您已经在系统上安装了FFmpeg并将其添加到了环境变量中。如果没有,请先安装FFmpeg并确保您的系统能够找到它。
