Client streamer javascript about fastapi-frame-stream HOT 8 CLOSED

Hi Tiago,
finally find the solution on stackoverflow, it seems (randomly) put localhost instread 127.0.0.1, it takes 2s every call... Now it works very smooth, I will let you know when I finish this project.

Many thanks

Hi @TiagoPrata , please see my new shared project, finally I solve the problem with Socket

Hi @Frenz86,

Thanks for your comment.

I've just tested the code you post and it worked pretty normal (see the attached video).

Do you need something faster than that or it is slower in your environment?

Hi Tiago,
that's make me crazy!!! I tryed on new virtualenv, on linux WSL2, but still got 3-4 FPS.
Please have a look into my repo. Something wrong?

These's a possibility you got the NASA's hardware?
I have also a quite powerfull laptop, what can cause the problem?

Many thanks

Hi @Frenz86,
Right now I'm testing it directly on Windows (instead of WSL2), inside a virtual environment. I don't know it the performance inside WSL2 can be affected.
Apart from that, my laptop is a very common one (i7-7850H, 16Gb RAM, Win10) so I don't think I'm taking any advantage of it.

The video I posted above was testing the same code you shared (which is in the file streamer_openc.py of your repository), but I also noted that you have another file where you're trying to use streamlit. Actually I've created this library exactly for this purpose. I was trying to send some frames to streamlit and I found no alternative.
I didn't test your streamlit file so far, but the OpenCV one looks fine here.

Later I'll try to have a better look on it, but unfortunately I have no other clue of what is happening for you :(

If you figure something out, please let me know.

Hi Tiago,
so weird, I also tested on a second laptop (W11 -i7 16GB also the second one), but nothign chnage.
Maybe could be the version of python (I'm using python 3.8). My idea is to use streamlit inside pyodide (stlite) and load the html thanks to jinja template, in order to have the streamer web all in one, with the API server, and make it runner inside a container on google Cloudrun, but latency is killing me :/

Many thanks
Let me know if you find the possible issue.

Hi @Frenz86,
Fantastic finding. I also didn't know that!

And, yes, please let me know when your project finishes.

Hi @TiagoPrata , I came across in a couple of good esample. It seems for realtime application, websocket would be easier, and memory optimize for the streaming video. I made some example in this repo, example1 and example2
https://github.com/Frenz86/FastAPI_StreamWebSocket

mi idea is to use fastapi as a machine learning websocket server, and with html, send the camera streaming and receive the object detection etc, for a simple cloud implementation. I am zero to html, do you know how to transform example2 with fastapi ed camera HTML on frontend?

Many thanks
