Hello,
I am trying to stream android phone camera and microphone to azure media service. I am trying the ExampleRTMP activity.
I have given the rtmp URL exposed by the Azure Media Service as input in ExampleRTMP activity.
But it keeps coming to the below highlighted line. I am testing it in Google Pixel Emulator.

if (rtmpCamera1.isRecording()
|| rtmpCamera1.prepareAudio() && rtmpCamera1.prepareVideo()) {
button.setText(R.string.stop_button);
rtmpCamera1.startStream(etUrl.getText().toString());
} else {
Toast.makeText(this, "Error preparing stream, This device cant do it",
Toast.LENGTH_SHORT).show();
}
In the console log, i can see the below messages
I/AudioEncoder: prepared
I/VideoEncoder: 0 encoders found
E/VideoEncoder: Valid encoder not found

This seems that you haven't h264 encoder.
Can you show me log from this method?:

for (String codec: CodecUtil.showAllCodecsInfo()) {
      Log.i("Pedro", codec);
}

Btw, on the live device, i saw some success. I saw the issue on emulator. Also, i am testing with both RTMP and RMPS, I hope RTMPS is not an issue. So, far, i am able to see the video but loosing the audio..trying to figure out why audio is not getting broadcasted. But the library seems to be super :)

You should be able to stream because you have OMX.google.h264.encoder. This could be a bug.

What do you mean with "i saw some success"? is it failing few times? can you reproduce this error 100% or only few times? (explain me the steps to reproduce)
Can you tell me emulator specifications to reproduce the problem? model, android api version (specify if google play or google api room), ram, arquitecture, etc.
Let me know if you are doing any modification in app example or you are using my app example without modifications (include modifications if used)
Make sure that you are using app example in last commit (master branch)

What do you mean with "i saw some success"? is it failing few times? can you reproduce this error 100% or only few times? (explain me the steps to reproduce)

In the previous test, i saw some audio loss when I used rtmps url instead of rtmp. But now, i have done the test again on another phone and it is broadcasting the audio. I will try again on the same phone tomorrow as i dont have it with me.

Can you tell me emulator specifications to reproduce the problem? model, android api version (specify if google play or google api room), ram, arquitecture, etc.

Please find below as attachment

Let me know if you are doing any modification in app example or you are using my app example without modifications (include modifications if used)

Currently no changes in the code, i was trying it on multiple devices to test.

Hello Pedro, I am experiencing the same issue, using an emulator and the default app from your repository, I also have reports from users with different type of devices having the problem, not sure where to go from there
