raspicam's Issues

Cannot get a smaller sized image that is full frame

Howdy, when I do

    Camera.setWidth ( 192 ); 
    Camera.setHeight ( 128 );

I get a tiny part of the middle of the sensor, when I'd like the full frame scaled down to 192x128

raspistill -w 192 -h 128 -o /tmp/raspicam_image.jpg does this fine, but this library does not.

Is there a way to get the library to scale down the image, or do I have to do it myself in code?

Thanks,
Marc

Missing Still functions:

    void RaspiCam_Still::setShutterSpeed(unsigned int ss) {
        _impl->setShutterSpeed(ss);
    }
    void RaspiCam_Still::setAWB_RB(float red_g, float blue_g) {
        _impl->setAWB_RB(red_g, blue_g);
    }

High cpu load

Hello, I'm using Camera V1.3 on Raspbrry Pi 4B, grab 1600x1200 CV_8UC3 18fps

it's take about 80% CPU usage(single core I think), is 80% normal?

Missed Private_Impl::getVideoStabilization

In Private_Impl class defined function setVideoStabilization, and this function param setted to State.videoStabilisation.
But, in Private_Impl not defined getVideoStabilization.

If necessary, i can create a merge request with the necessary changes.

Sorry for my bad english.

still mode problem

still mode in camera V2.1 seems has a problem.
when capturing starts after a while it can not grab any other frame

High Quality Camera

I recently got a few of the high quality camera sensors. Is there any support for this? When I use these sensors, I still get the 1280 × 960 images.

3 fixes for simpletest_raspicam.cpp on raspbian

Hi,

I just checked out the latest version on raspbian/rPi4.
The included example works fine, but when I tried to compile the sample code given on
http://www.uco.es/investiga/grupos/ava/node/40

1. sleep is not found, I had to add
   #include <unistd.h>

2. build is missing -L/opt/vc/lib/. I had to build with
   g++ simpletest_raspicam.cpp -o simpletest_raspicam -I/usr/local/include -L/opt/vc/lib/ -lraspicam -lmmal -lmmal_core -lmmal_util

3. runtime warning

root@rPi4b:~/raspicam/example# ./simpletest_raspicam 
Opening Camera...
Sleeping for 3 secs
/root/raspicam/src/private/private_impl.cpp:179 :Private_Impl::retrieve type is not RASPICAM_FORMAT_IGNORE as it should be
Image saved at raspicam_image.ppm

not sure what the fix should be, but the ppm file works, so that's the important part

mmal_component_create_core: could not find component 'vc.ril.camera'

I am using raspbery Pi 4 SoC with Ubuntu 20.10 64bit OS and trying to use raspberry Pi HD Camera.

I am able to compile 'raspicam' and below example code successfully, but when I am running this test code it gives me error.
`

#include <raspicam/raspicam.h>
#include <raspicam/raspicamtypes.h>

int main()
{
raspicam::RaspiCam camera;
camera.open(true);
camera.grab();
return 0;
}
`

Error

mmal_component_create_core: could not find component 'vc.ril.camera'

On the same configuration I am able to run raspistill without any issues so camera is working fine.
