Raspberry pi Camera V2 using Qt
-
Hello,
I have already read a lot of topics about this but I still don't have solution so I'm asking here.What is the easiest way to use Raspberry Pi camera V2 in Qt Creator on RPi?
I read about raspicam, but I don't know how to use. I downloaded source code from git but It needs a lot of added Android headers to download and they are useless for me, because I work on RPi. After downloading all headers it shows a lot of errors.
Class QCamera is not working here.One way I know is write easy python codes and call them from Qt but I'm not fan of counts of QProcess.
Do you have any idea?
At all, I need to do:- capture picture
- capture video
- stream video
Thanks for your help

Hi,
AFAIK, QtGstreamer is your best bet of these actives.

Based on https://wiki.qt.io/RaspberryPi2EGLFS#Qt_Multimedia
Unfortunately the GStreamer-based multimedia stuff is not quite usable at the time of writing - accelerated video works only sometimes (and with glitches), while the camera is just broken.
I am a bit upset because of this and trying to find different way to get Camera stream on raspberry pi.
Here is nice source:

but it is impossible to have it cross-compiled because this library depends on raspberry pi specific packages. However, it runs fine when building and compiling on raspberry pi board directly.
