FFmpeg Android执行

Question

在Windows上，我可以使用ffmpeg.exe用以下代码剪切视频

无法在Android中使用ffmpeg。我用gradle在我的应用程序中抓取ffmpeg。

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5'
}

我的方法中有这些行

VideoIn = getInternalDirectoryPath() + "/Download/Ab.mp4";
VideoOut = getInternalDirectoryPath() + "/Download/Ab1.mp4";

try {
ffmpeg.execute("ffmpeg -i " + VideoIn + " -ss 00:00:03 -c:v libx264 -crf 17 -t 00:00:5 " + VideoOut + " -y",null);
}
catch (FFmpegCommandAlreadyRunningException e) { 
e.printStackTrace();
}

显示此错误：运行exec（）时出错。命令：[/ data / data / com.videoeditor.myname.myapp / files / ffmpeg，ffmpeg，-i，/ storage / emulated / 0 / Download / Ab.mp4，-ss，00：00：03，-c： v，libx264，-crf，17，-t，00：00：5，/ storage / emulated / 0 / Download / Ab1.mp4，-y]工作目录：null环境：null

这种方法有什么问题？谢谢你的帮助

好的，我找到了答案：这种使用ffmpeg的方法在cmd中不需要“ ffmpeg”

简单的视频剪辑示例：

 /**
 * Returns the path to internal storage ex:- /storage/emulated/0
 *
 * @return
 */
private String getInternalDirectoryPath() {
    return Environment.getExternalStorageDirectory().getAbsolutePath();
}

VideoIn = getInternalDirectoryPath() + "/Download/Ab.mp4";
VideoOut = getInternalDirectoryPath() + "/Download/Ab1.mp4";

private void CutVideo(){
try {
     ffmpeg.execute("-i "+VideoIn+" -ss 00:01:00 -to 00:02:00 -c copy "+VideoOut ,
new ExecuteBinaryResponseHandler() {

                @Override
                public void onStart() {
                //for logcat
                    Log.w(null,"Cut started");
                }

                @Override
                public void onProgress(String message) {
                //for logcat
                    Log.w(null,message.toString());
                }

                @Override
                public void onFailure(String message) {

                    Log.w(null,message.toString());
                }

                @Override
                public void onSuccess(String message) {

                    Log.w(null,message.toString());
                }

                @Override
                public void onFinish() {

                    Log.w(null,"Cutting video finished");
                }
            });
        } catch (FFmpegCommandAlreadyRunningException e) {
            // Handle if FFmpeg is already running
            e.printStackTrace();
            Log.w(null,e.toString());
        }
}
