視頻轉換同時獲取視頻大小和時長

}

獲取視頻封面

package org.jeecg.common.util;import com.github.kokorin.jaffree.StreamType;
import com.github.kokorin.jaffree.ffmpeg.*;import javax.imageio.ImageIO;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;
import java.util.concurrent.atomic.AtomicLong;public class JaffreeVideoConverter {public static void main(String[] args) {// 輸入和輸出文件路徑Path input = Paths.get("D:/input.wmv");Path outputs = Paths.get("D:/");FFmpegResult result = FFmpeg.atPath().addInput(UrlInput.fromPath(input)).addOutput(FrameOutput.withConsumer(new FrameConsumer() {private long num = 1;@Overridepublic void consumeStreams(List<Stream> streams) {// All stream type except video are disabled. just ignore}@Overridepublic void consume(Frame frame) {// End of Streamif (frame == null) {return;}try {String filename = "frame_" + num++ + ".png";Path output = outputs.resolve(filename);ImageIO.write(frame.getImage(), "png", output.toFile());} catch (Exception e) {e.printStackTrace();}}})//控制截多少張圖,這里我只需要截取一張.setFrameCount(StreamType.VIDEO, 1l)//每十秒截取一張 從0開始.setFrameRate(0.1).disableStream(StreamType.AUDIO).disableStream(StreamType.SUBTITLE).disableStream(StreamType.DATA)).execute();}
}

除此之外，還可以合成視頻，截取視頻等功能
