compile 'com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5'library. But there is one more problem when i execute any command that time i got errorWorking Directory: null Environment: nulli have to declare permission in manifest file and code execute time also check file exist or not. kindly check my code and how to fix it ? please share your some helpful suggestions. Thanks in advance.MyCode
if (videoFile.exists()) {
String vidInput = videoFile.getAbsolutePath();
String cmd = "-i " + vidInput + " -map_metadata:s:a 0:g " + vidoutpath;
FFmpeg fFmpeg = FFmpeg.getInstance(getApplicationContext());
fFmpeg.execute(cmd, new FFmpegExecuteResponseHandler() {
@Override
public void onSuccess(String message) {
Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
}
@Override
public void onProgress(String message) {
}
@Override
public void onFailure(String message) {
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}
@Override
public void onStart() {
}
@Override
public void onFinish() {
}
});
}Above code in when i pass only
-versioncommand that time also get same problem.Manifest File in uses Permission

How to decrease the latency of the RTP streaming with ffmpeg in Android ?
24 août 2018, par Douglas Lima DantasI’m creating a App that do a RTP streaming. It uses a ParcelFileDescriptor pipe pair, where a MediaRecorder writes in the pipe while the ffmpeg receives the audio from the pipe and sends by RTP.
In my desktop, using the same wifi router, I receive the RTP stream using ffplay, and it has a delay between 5s 10s.
I tried capture audio using ffmpeg in Android, but itsn’t possible. I tried to use ffplay -fflags nobuffer, use MIC as source, change the encoder, etc.
I need the lowest delay possible. How can I do it ?
The code :
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
MediaRecorder mediaRecorder;
AudioRecord record;
MediaPlayer mediaPlayer;
ParcelFileDescriptor[] pipePair;
ParcelFileDescriptor pipeRead;
ParcelFileDescriptor pipeWrite;
Process ffmpegProc;
