Description

Hi everyone, I'm trying to record&play only audio but i keep getting the same error. org.bytedeco.javacv.FFmpegFrameRecorder$Exception: No audio output stream (Is audioChannels > 0 and has start() been called?) (For more details, make sure FFmpegLogCallback.set() has been called.)

recorder.recordSamples(sampleRate, numChannels, sBuff); //Error Line

Contributor guide

Research direction
Ensure audioChannels > 0 and start() has been called before calling recordSamples. Verify the audio stream setup in the FFmpegFrameRecorder configuration.
