Passing Video Callback Function to Audio Callback Function

🎈 Using Streamlit
1

Summary

Is there a way to pass the returned frame from video callback to audio callback for further processing within the same webrtc_streamer?

Also, if possible, can we pass a webrtc_streamer.audio_receiver to another webrtc_streamer instance?

Example

I want to do something like this

webrtc_streamer(....,queued_audio_frames_callback=queued_audio_frames_callback(some_other_callback_function))

If applicable, please provide the steps we should take.

Hi @Anis

Both video and audio input/output can be processed via the av.VideoFrame and av.AudioFrame of PyAV library.

A few examples of processing video frames are provided in the package’s GitHub repo (GitHub - whitphx/streamlit-webrtc: Real-time video and audio streams over the network, with Streamlit.) and the same concept can be applied to audio.

Hope this helps!
