Question

我正在开发一个Android应用程序。在我的应用程序中，我希望使用 ffmpeg 库录制实时流媒体视频。我为录制直播视频编写了一个代码，但它无法正常工作。它显示了一些错误。如果有人知道这一点，请帮助我。

这是我用来录制视频的代码

try {

            fFmpeg.execute(new String[]{"ffmpeg -i rtsp://192.168.1.1:6667/streamhd -acodec copy -vcode c copy"+String.valueOf(getCacheDir())+"/MyVideo.mp4"}, new ExecuteBinaryResponseHandler() {

                @Override
                public void onSuccess(String message) {
                    Log.d("fffffff", "FFmpeg cmd success");
                }

                @Override
                public void onFailure(String message) {
                    Log.d("ffffffffffff", message.toString());
                }
            });
        }catch (FFmpegCommandAlreadyRunningException e) {
            // Handle if FFmpeg is already running
            e.printStackTrace();
            Log.w(null,e.toString());}

当我执行此块时，我收到以下错误消息。

最后我建立了解决方案。在android中，您必须将FFMpeg.execute（）方法的参数作为String数组传递。

使用以下代码

 String[] cmd = {"-i" , "rtsp://192.168.1.1:6667/streamhd" , "-fs" , "25M" ,  "-b" , "900k" , "-vcodec" , "copy" , "-r" , "60" , "-y" ,"-movflags","+faststart",""+getNextFileName() } ;

 try {

            fFmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {


                @Override
                public void onSuccess(String message) {
                    Log.d("fffffff", "FFmpeg cmd success");
                }

                @Override
                public void onFailure(String message) {
                    Log.d("ffffffffffff", message.toString());
                }
                @Override
                public void onProgress(String message) {
 }
                @Override
                public void onFinish() {
                    Log.d("finish",""+fFmpeg.isFFmpegCommandRunning());

                }

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

无法使用FFMPEG在Android中复制RTSP流式视频
