low FPS (0.2 fps) on windows 10 without EdgeTPU

[gyang2020]

Live stream from IP Cam (RTSP) with the stream script works, but the fps is about 5 seconds per frame. Also tested the test.mp4 file, similar results. I narrowed it down to the .invoke() line. Is this somewhat expected because TFlite is not for windows? Thanks!

hey nice to hear that youre working on this project.

i immediatelly tested the webcam script and my fps is also under 0.2 fps. i dont know whats the problem, my resolution on webcam is 640x480 with 30fps.

before i test it on the RPi 4 i wanted to make sure its working on my laptop, but its so slow... did you find a solution?

Hi, we ended up using rpi4 without tpu, it's 4fps, the archetcture of the processor is the problem I guess. May also be the operating system

@gyang2020
i have not tried the script on the raspberry pi yet. i wanted to try detect.tflite on the laptop via the webcam first and i don't understand the FPS is at 1.0 at the beginning and drops to 0.12 fps afterwards.

it's really strange and i have no explanation for it :(
