Description

I encountered a problem in the development process. The Functional requirement is to obtain audio data through the sdk provided by the cartridge manufacturer. The audio data is continuously obtained through the callback method, and each time a frame of audio is returned, the format is a byte array, and the encoding is aac; I use JavaCV for streaming the RSR server. The current idea is to store the audio byte array obtained by the callback in a blocking queue, and start another thread to consume the queue audio data, which is streamed through FFmpegFrameRecorder. However, what I get from the streaming server is that kind of intermittent and harsh noise. I write the audio data as an AAC file and the streaming is playing normally. Can you provide some help？

Contributor guide

Research direction
Compare the saved AAC file with the streamed output to identify differences in audio parameters. Check the FFmpegFrameRecorder settings (codec, sample rate, channels) and verify the audio byte array is correctly framed.
