linux上使用ffmpeg 实现视频截图

import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; public class Test { // 视频缩略图截取 // inFile 输入文件(包括完整路径) // outFile 输出文件(可包括完整路径) public static boolean transfer(String inFile, String outFile,String startTime) { String command = "ffmpeg -i " + inFile + " -y -f image2 -ss "+startTime+" -t 00:00:01 -s 480x450 " + outFile; try { Runtime rt = Runtime.getRuntime(); Process proc = rt.exec(command); InputStream stderr = proc.getErrorStream(); InputStreamReader isr = new InputStreamReader(stderr); BufferedReader br = new BufferedReader(isr); String line = null; while ((line = br.readLine()) != null) System.out.println(line); } catch (Throwable t) { t.printStackTrace(); return false; } return true; } public static void main(String[] arg){ String inFile ="/home/local/test/test.mp4"; String outFile ="/home/local/test/test.jpg"; boolean transfer = Test.transfer(inFile, outFile,"0"); System.out.print(transfer); } }
