Re: Raspberry PI 4B and Ubuntu 19.10

Alright i will first try to OC for see and if not change i will reinstall all with Raspbian. But normally, for everybody it should be smooth right ? Is it normal or not in my case ? The Ubuntu desktop packages haven't received any kind of optimization for the Pi so I wouldn't expect them to operate...

Re: Ubuntu server 18.04.3 LTS Black Screen on boot, pi 4

Sorry, this is us messing up! The forthcoming 18.04.4 release (*not* .3) will bring support for the Pi4, but the .4 release got delayed a week to deal with a couple of issues on the simultaneous Core18 release (which also brings Pi4 support). Unfortunately, it appears updating the website didn't get...

Re: Python or C++ for fast recording?

Just to add a little to this topic: when it comes to simply recording data from the camera the choice of language will make little/no difference to the speed you can reach. All the serious processing happens on the GPU, which then sends packets of output to whatever you've got in userspace. So wheth...

Re: New 8MP Camera - Q&A thread

One possible explanation is that you weren't using the "real" maximum resolution. Prior to picamera 1.11 being released, the MAX_RESOLUTION value was fixed at (2592, 1944), i.e. the max resolution of the V1 module. Hence even if you had a V2 module attached and set MAX_RESOLUTION you'd still just g...
