I'm trying to implement this for projects with esp-idf, junior.2x does the job but it's a little bit spaghetti. What exactly is the code doing?(Edit : btw thanks so much, your project saved me a lot of time) (I will publish after I finish, ofc)

You would have to be more specific.

Hi @Yuxekova , I don't know exactly the code works, but can tell you it records a format called MMPEG,

basically it stores a sequence of JPG files, one after other, the full frames.

AVI also has a header to identify this format, in the code you can found it,

but the rest of the process, as far I can understand, should be ask the camera driver for the JPG compressed image, and then append to the avi file. maybe some closing mark is also needed,

I hope you can learn more about the format mmpeg, and the codes makes more sense for you (I had no time to investigate further).
