Linux下使用ffmpeg从视频提取图片

Linux下可以通过ProcessBuilder来创建进程，执行相应的命令。Process的waitFor()等待进程执行完毕。

private static synchronized boolean processFLV(String oldfilepath) {

List<String> commend = new java.util.ArrayList<String>();

commend.add("//root//test//ffmpeg-2.2.4-64bit-static//ffmpeg");

commend.add("-i");

commend.add("//root//test//Wildlife.wmv");

commend.add("-r");

commend.add("1");

commend.add("-q:v");

commend.add("2");

commend.add("-f");

commend.add("image2");

// commend.add("//root//test//images//image-%d.jpeg");

commend.add(oldfilepath+"//image-%d.jpeg");

try {

// ProcessBuilder builder = new ProcessBuilder();

ProcessBuilder builder = createProcessBuilder();

builder.command(commend);

Process process = builder.start();

if(process.waitFor() != 0)

{

System.out.println("process.waitFor() != 0");

}else {

System.out.println("process.waitFor() == 0");

}

commend.clear();

} catch (Exception e) {

e.printStackTrace();

return false;

}

return true;

}
