How to use it:

To display an mjpeg stream on a web page, just put the address in an image tag:

How it works:

The server loads the same jpeg file from the file system and sends it to the web browser.

It does this continuously.

That's pretty much it. It's less than 30 lines of code - have a look.

It is the responsibility of something else to keep replacing that file with the latest frame in the video stream.

For example, the following command reads frames from a video file and constantly replaces the output filename with the current frame:

ffmpeg -y -re -stream_loop -1 -i monster-family-2-teaser_h480p.mov -f image2 -update 1 /dev/shm/img.jpeg

Mixing sync and async apis?

Cool project! Thanks for sharing.

I haven't done much async Python but it looks like you are using syncronous apis within async code which blocks the event loop. AFAIK the core file apis in Python are sync. At least on node.js in this would be a bad practice.

https://github.com/bootrino/maryjane/blob/a1d7a3376a7a03e195e31221f473beeea33b895f/mjpegserverpython.py#L27-L28

I think you should use some async version of open()/read() 🤔
