I plugged a USB microphone into TV to record external audio. In my .NET app I can detect it with AudioManager.GetConnectedDevices(). To record audio I set the privileges (microphone) and follow the instructions here:
https://docs.tizen.org/application/dotnet/guides/multimedia/raw-audio/
I tried both methods sync and asysnc:
https://docs.tizen.org/application/dotnet/api/TizenFX/API11/api/Tizen.Multimedia.AudioCapture.html
https://docs.tizen.org/application/dotnet/api/TizenFX/API11/api/Tizen.Multimedia.AsyncAudioCapture.html
I instantiate AudioCapture or AsyncAudioCapture objects and when I invoke the Prepare() method the app crashes without any exception or error message.
Simplified code snippet:
AudioCapture audioCapture = new AudioCapture(44100, AudioChannel.Mono, AudioSampleType.S16Le);
int bufferSize = audioCapture.GetBufferSize();
const int RecordingSec = 1;
bufferSize *= 10 * RecordingSec;
audioCapture.Prepare(); // THIS LINE CRASHES
byte[] buffer = audioCapture.Read(bufferSize);
The same result is on two different models (Tizen 6.0 and Tizen 6.5).
How can I record audio from microphone on Tizen TV? What am I missing?
