I have the same problem, although I'm not even doing anything particularly heavy in my loop.
while ctx.state.playing:
with lock:
is_speaking = info["is_speaking"]
audio_frame_id = info["audio_frame_id"]
I even get delay if the only thing in the while loop is:
while ctx.state.playing:
pass
The lines above cause a delay of multiple seconds in the video delivered via webrtc:
def video_frame_callback(frame): return frame
My environment is:
OS: macOS Ventura 13.4.1 (arm)
Shell: zsh
Browser: Firefox 122
Python: 3.10.13
streamlit: 1.31.1
streamlit-webrtc: 0.47.1
from streamlit-webrtc.
I think it's because Python doesn't execute CPU-bound tasks in parallel even in multiple threads due to the GIL.
Off-loading the cpu-heavy tasks to another "process" by using multiprocessing
might be a solution.
