java调用ffmpeg一直卡住。

Question

用Cmd 执行如下命令是可以成功转换的： {代码...} 但是用java processBuider或者runtime都会一直卡住。

黄舟 · Answer

Print Progress 的 errorStream and take a look

Runtime runtime = Runtime.getRuntime();

String[] cmd = {"cmd1", "cmd2"};

Process exec = runtime.exec(cmd);

exec.getErrorStream();

Also, can you post the code?
