Question

我遇到的问题很奇怪。我的Android上安装了一个FFMPEG可执行二进制库，我正在尝试执行此命令

ffmpeg -loop 1 -i /storage/emulated/0/image.jpg -i /storage/emulated/0/input.mov -filter_complex '[0:v][1:v] overlay' -shortest /storage/emulated/0/output.mp4

我的JAVA代码看起来像

try {
            Runtime.getRuntime().exec("chmod 700 " + mFfmpegPath);
            cmd.add(mFfmpegPath);
            cmd.add("-loop");
            cmd.add("1");
            cmd.add("-i");
            cmd.add("/storage/emulated/0/image.jpg");
            cmd.add("-i");
            cmd.add("/storage/emulated/0/pizza.mov");
            cmd.add("-filter_complex");
            cmd.add("'[0:v][1:v] overlay'");
            cmd.add("-shortest");
            cmd.add("-vcodec");
            cmd.add("-libx264");
            cmd.add("-strict");
            cmd.add("experimental");
            cmd.add("/storage/emulated/0/output22.mp4");

            final ProcessBuilder pb = new ProcessBuilder(cmd);
            pb.redirectErrorStream();
            final Process p = pb.start();
            Log.i("FFMPEG","stdError= " + getSTD(p.getErrorStream()));
            p.waitFor();
            return run;
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

由于某种原因，我的执行没有完全完成，它停止了。它甚至没有在我的Android存储中创建输出文件。以下是流程

请帮助:(

Answer 1

我解决了！我删除了

中的单引号

cmd.add("'[0:v][1:v] overlay'");

成为

cmd.add("[0:v][1:v] overlay");

Android Java Process上的FFMPEG命令无法完全执行
