cython malloc-olt memória felszabadítása python-ból

Köszi, ez lesz a megoldás!

Hát lehet mégis kellene valami python only megoldás, mert ez a cython (ahogy sejtettem) egy masszív szopóroller...

Kiforkoltam, megfixeltem majd:

pi@raspberrypi:~/brute_force2/sw $ pip3 install -e git+https://gitlab.com/martonmiklos/PyV4L2Camera.git@dealloc_buffer_on_close#egg=PyV4L2Camera

camera.c WTF?

Ja a setup.py-nak van egy --use-cython argumentuma ami azt állítja, hogy c vagy pyx fájloakt fordítson. Tegyük defaulttá!

(pip3 install v4l2 megvolt már)

Nem azzal van a bajom, hogy hogyan kell cython-ban megoldani, hanem az, hogy a megpatkolz modult hogyan fordítsam le, hogy használni is tudjam (ld. fentebb)
