Hi there,

I'm trying to create a RTMP streaming into a server.
I created first my project with old and deprecated Camera API, and it works perfectly fine.

Then, I tried with the new API, CameraApi2, and I have an issue :
When I start my FFMpegFrameRecorder, I have :

W/System.err: Error: [rtmp @ 0xd2474480] Cannot open connection tcp://10.1.10.243:1935
I/System.out: [aac @ 0xddcb0c00] Qavg: nan

W/System.err:     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:695)

You can see there is a TCP fail connection with FFmpegLogCallback, but I don't understand because on the same network with the same server it works..

I created my project and started it with the sample andrid-Camera2Video of Google.

I init my recorder in this function :

private void setUpMediaRecorder() throws IOException {
        final Activity activity = getActivity();
        if (null == activity) {
            return;
        }
        FFmpegLogCallback.set();
        if (yuvImage == null) {
            yuvImage = new Frame(mVideoSize.getWidth(), mVideoSize.getHeight(), Frame.DEPTH_UBYTE, 2);
            Log.i(TAG, "create yuvImage");
        }


        Log.i(TAG, "ffmpeg_url: " + ffmpeg_link);

        recorder = new FFmpegFrameRecorder(ffmpeg_link, mVideoSize.getWidth(), mVideoSize.getHeight(), 1);
        recorder.setFormat("flv");
        recorder.setSampleRate(sampleAudioRateInHz);
        // Set in the surface changed method
        recorder.setFrameRate(frameRate);

        Log.i(TAG, "recorder initialize success");

        audioRecordRunnable = new AudioRecordRunnable();
        audioThread = new Thread(audioRecordRunnable);
        runAudioThread = true;
}

Then my ImageReader is created like this :

mImageReader = ImageReader.newInstance(mVideoSize.getWidth(), mVideoSize.getHeight(),
                                                   ImageFormat.YUV_420_888,
                                                   1);
            mImageReader.setOnImageAvailableListener(mOnImageAvailableListener, mBackgroundHandler);
            surfaces.add(previewSurface);
            surfaces.add(mImageReader.getSurface());

Finally, my Listener is called like this :

private final ImageReader.OnImageAvailableListener mOnImageAvailableListener
            = new ImageReader.OnImageAvailableListener() {

        @Override
        public void onImageAvailable(final ImageReader reader) {
            mBackgroundHandler.post(new Runnable() {
                @Override
                public void run() {
                    if (audioRecord == null || audioRecord.getRecordingState() != AudioRecord.RECORDSTATE_RECORDING) {
                        startTime = System.currentTimeMillis();
                        return;
                    }
                    Image img = reader.acquireNextImage();
                    final ByteBuffer buffer = img.getPlanes()[0].getBuffer();
                    byte[] bytes = new byte[buffer.remaining()];
                    buffer.get(bytes, 0, bytes.length);
                    img.close();

                    ((ByteBuffer) yuvImage.image[0].position(0)).put(bytes);

                    Log.v(TAG, "Writing Frame");
                    long t = 1000 * (System.currentTimeMillis() - startTime);
                    if (t > recorder.getTimestamp()) {
                        recorder.setTimestamp(t);
                    }
                    try {
                        recorder.record(yuvImage);
                    } catch (FFmpegFrameRecorder.Exception e) {
                        Log.v(TAG, e.getMessage());
                        e.printStackTrace();
                    }

                }
            });
        }

My FFMpegFrameRecorder is called here :

mCameraDevice.createCaptureSession(surfaces, new CameraCaptureSession.StateCallback() {

                @Override
                public void onConfigured(@NonNull CameraCaptureSession cameraCaptureSession) {
                    mPreviewSession = cameraCaptureSession;
                    updatePreview();
                    getActivity().runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            // UI
                            mButtonVideo.setText(R.string.stop);
                            mIsRecordingVideo = true;

                            try {
                                recorder.start();
                            } catch (FFmpegFrameRecorder.Exception e) {
                                Log.d(TAG, e.getMessage());
                                e.printStackTrace();
                            }
                            startTime = System.currentTimeMillis();
                            recording = true;
                            audioThread.start();
                            // Start recording
                            //mMediaRecorder.start();
                        }
                    });
                }

I really don't understand, any help would be appreciate,

Thanks a lot,

BTW, this sounds like a question for Stack Overflow, so you might want to try to ask there instead.

JeanBeaurepaire · 2017-02-08T13:25:33Z

Ok, but the stacktrace appears in the code of your library. Could it be because I'm using Android 6.0 and TCP connection is different than devices below Android 5.0 ? Is it someone who achieved to create a RTMP stream with API>23 ?

saudet · 2017-02-08T13:48:27Z

No it doesn't appear in my code, it appears in the code of FFmpeg:

W/System.err: Error: [rtmp @ 0xd2474480] Cannot open connection tcp://10.1.10.243:1935

If you think this is a bug in FFmpeg, then please post a ticket upstream over there.

JeanBeaurepaire · 2017-02-08T14:23:19Z

Yes maybe it is, but how can I have a better stacktrace than this line ? It doesn't explain why, or which part of their code is wrong

saudet · 2017-02-09T00:30:48Z

You could try to call av_log_set_level(AV_LOG_TRACE) during init and see what that gives.

JeanBeaurepaire · 2017-02-09T15:36:41Z

I tried to fix with your thread on java.lang.UnsatisfiedLinkError, but it seems different..

Someone has the same issue in StackOverflow .

Thank you for your huge help,

saudet · 2017-02-09T23:48:11Z

Those are just warnings, you can ignore those "errors".

saudet · 2017-02-12T12:49:52Z

Actually, it seems like Android 7.0 changed a few things:
https://developer.android.com/about/versions/nougat/android-7.0-changes.html

JeanBeaurepaire · 2017-02-13T09:43:24Z

Oh yes interesting !
https://developer.android.com/about/versions/nougat/android-7.0-changes.html#ndk.
Can I resolve it in my app or do you must update your library ?

saudet · 2017-02-13T10:54:01Z

Removing the android-arm.properties and android-x86.properties files from your APK might work.

JeanBeaurepaire · 2017-02-13T15:42:12Z

OK i removed those 2 files in javacpp.jar, and no more library error. But I have still the same issue
