MMAL is not (yet) supported in 64-bit environments.

Hello!

I'm developing a medical device. I'm using picamera with Python 3.9, on a PI 4, 64bits. Or rather, I'm trying to use it, but it complains of this lib missing.

Is there any news on the subject? Can't this lib just be compiled for 64 bits, or are there dependencies and ramifications?

It will not work when compiled for 64 bits, and is unlikely to do so - our emphasis now is on libCamera (that does work in both 32 and 64 bits) and a new version of picamera based on it. However, that's not ready, and won't be for some time.

Note, that our 64bi distro has not been released which means it is still very much a prototype and should not be used for commercial systems. Unless you specifically need it, I would suggest remaining on Buster and 32bit where everything will work fine. There are only minor performance benefits to 64bit anyway.

Thanks James!

We'll be eagerly waiting for the new picamera (and possibly the official 64 bits OS distro) and until then we'll follow your suggestion and put 64bits back in the drawer. Our issue is that we have legacy code on picamera. My CV engineer actually thinks he could use ffmpeg directly.

Before I forget, you guys are doing a terrific job with the "Pie". Thank you!

Raspberry Pi OS (64-bit) is officially released, is any update on the picamera?

[6by9]

libcamera is the supported solution on 64bit systems.

There is also this updated picamera2 release. https://forums.raspberrypi.com/viewtopic.php?t=335832
