add new Control

[Lusifug]

Is there a way to add new values to ControlInfoMap for Camera? I have added new controls to control_ids and ipa_base, but when I try to use them, I receive an error message: ERROR Controls controls.cpp:1069 Control 0x0000000c is not valid for /base/soc/i2c0mux/i2c@1/imx708@1a According to the validation method, it seems like this happens cause Camera ControlInfoMap doesn`t have such controls

[naushir]

Can you expand on what you are trying to do here? The control error above is for a V4L2 control error, not a libcamera control.

[Lusifug]

I`m trying to add a possibility to pass value via controls, to change params for existing contrast algorithm on the fly, such as low level, low histogram...

[naushir]

Unfortunately I am still not sure what you are trying to do. Would you be able to share snippets of source code showing you setting up this new control and how use use it please?

[Lusifug]

I try to add a possibility to change contrast enchancemet algorithm parameters in real-time using a set control method

I`ve added setters to to have then in control_ids.h after build Contrast class:

    void setConfigLoHistogram(double loHistogram) override;
    void setConfigLoLevel(double loLevel) override;
    void setConfigLoMax(double loMax) override;
    void setConfigHiHistogram(double hiHistogram) override;
    void setConfigHiLevel(double hiLevel) override;
    void setConfigHiMax(double hiMax) override;

and interface to ContrastAlgorithm class:

    virtual void setConfigLoHistogram(double loHistogram) = 0;
    virtual void setConfigLoLevel(double loLevel) = 0;
    virtual void setConfigLoMax(double loMax) = 0;
    virtual void setConfigHiHistogram(double hiHistogram) = 0;
    virtual void setConfigHiLevel(double hiLevel) = 0;
    virtual void setConfigHiMax(double hiMax) = 0;

in IpaBase method applyControls I`ve added cases for this new controls:

case controls::CONTRAST_LO_HISTOGRAM: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_LO_HISTOGRAM - no contrast algorithm";
                break;
            }

            contrast->setConfigLoHistogram(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastLoHistogram,
                           ctrl.second.get<float>());
            break;
        }

        case controls::CONTRAST_LO_LEVEL: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_LO_LEVEL - no contrast algorithm";
                break;
            }

            contrast->setConfigLoLevel(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastLoLevel,
                           ctrl.second.get<float>());
            break;
        }

        case controls::CONTRAST_LO_MAX: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_LO_MAX - no contrast algorithm";
                break;
            }

            contrast->setConfigLoMax(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastLoMax,
                           ctrl.second.get<float>());
            break;
        }

        case controls::CONTRAST_HI_HISTOGRAM: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_HI_HISTOGRAM - no contrast algorithm";
                break;
            }

            contrast->setConfigHiHistogram(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastHiHistogram,
                           ctrl.second.get<float>());
            break;
        }

        case controls::CONTRAST_HI_LEVEL: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_HI_LEVEL - no contrast algorithm";
                break;
            }

            contrast->setConfigHiLevel(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastHiLevel,
                           ctrl.second.get<float>());
            break;
        }

        case controls::CONTRAST_HI_MAX: {
            RPiController::ContrastAlgorithm *contrast = dynamic_cast<RPiController::ContrastAlgorithm *>(
                controller_.getAlgorithm("contrast"));
            if (!contrast) {
                LOG(IPARPI, Warning)
                    << "Could not set CONTRAST_HI_MAX - no contrast algorithm";
                break;
            }

            contrast->setConfigHiMax(ctrl.second.get<float>());
            libcameraMetadata_.set(controls::ContrastHiMax,
                           ctrl.second.get<float>());
            break;
        }

and in control_ids.yaml I`ve added new values for new controls:

  - ContrastLoHistogram:
      type: float

  - ContrastLoLevel:
      type: float

  - ContrastLoMax:
      type: float

  - ContrastHiHistogram:
      type: float

  - ContrastHiLevel:
      type: float

  - ContrastHiMax:
      type: float

[naushir]

That all seems reasonable enough. Have you definitely re-compiled all of libcamera and your applications to make sure the new control values are addressed correctly?

On a side note, perhaps you don't need to do this and can adjust the histogram through the camera tuning file instead?

[Lusifug]

for compiling libcamera I used these commands, as described in the manual

meson setup --prefix=/usr build
sudo ninja -C build install

changes in the camera tuning file are not possible in real-time, cause it requires to restart camera app, which takes time. please correct me if I`m wrong

[naushir]

Once you rebuild libcamera, you must rebuild libcamera-apps (or whatever application you are running) otherwise the control enum values will be mismatched between libcamera and the application.

You are correct, we cannot change the tuning file parameters in real-time.

[Lusifug]

I use my own simple testing app, to take pictures via libcamera, i rebuild before every use:

#include <iostream>
#include <iomanip>
#include <memory>
#include <thread>
#include <fstream>
#include <fcntl.h>

    }

    const std::map<const Stream *, FrameBuffer *> &buffers = request->buffers();
    for (auto bufferPair : buffers) {
        FrameBuffer *buffer = bufferPair.second;

        const libcamera::FrameBuffer::Plane &plane = buffer->planes().front();
        void *frameData = mmap(nullptr, plane.length, PROT_READ, MAP_SHARED, plane.fd.get(), 0);

        std::string photoFilename = "captured_photo_final.ppm";
        std::ofstream photoFile(photoFilename, std::ios::out | std::ios::binary);

        photoFile << "P6\n";

    }
}

    std::unique_ptr<CameraConfiguration> config = camera->generateConfiguration( { StreamRole::Raw } );
    StreamConfiguration &streamConfig = config->at(0);
    streamConfig.pixelFormat = libcamera::formats::BGR888;
    streamConfig.size = libcamera::Size(1920, 1080);
    config->validate();
    camera->configure(config.get());

    FrameBufferAllocator *allocator = new FrameBufferAllocator(camera);

    int ret = allocator->allocate(streamConfig.stream());
    if (ret < 0) {
        std::cerr << "Can't allocate buffers" << std::endl;
        return -ENOMEM;

        return -ENOMEM;
    }

    ret = request->addBuffer(stream, buffer.get());
    if (ret < 0)
    {
        std::cerr << "Can't set buffer for request"
              << std::endl;
        return ret;
    }

    camera->requestCompleted.connect(requestComplete);

    camera->start();
    ControlList &reqcon = request.get()->controls();
    reqcon.set(controls::ContrastLoHistogram, 0.0);
    reqcon.set(controls::ContrastLoLevel, 0.1);
    reqcon.set(controls::ContrastLoMax, 20000);
    reqcon.set(controls::ContrastHiLevel, 1.0);
    reqcon.set(controls::ContrastHiHistogram, 0.9);
    reqcon.set(controls::ContrastHiMax, 10000);
    camera->queueRequest(request.get());
    std::this_thread::sleep_for(1000ms);
    camera->stop();
    allocator->free(stream);
    delete allocator;
    camera->release();
    camera.reset();
    cm->stop();

    return 0;
}

when I set standard controls, it works perfectly, but when I`m trying same with new controls, I receive error, and even if disable this error, nothing changes on the photo

[naushir]

Are you able to run under gdb and put a breakpoint on the line that caused the error and share a callstack?

[Lusifug]

thread was replaces with 🧵, not sure how to fix this

[naushir]

If you look at frame 2 and frame 1, can you see the line of code and what control is trying to be set?

[Lusifug]

not sure what you mean by frame 1 and frame 2, do you mean this line of code? 1070 if (validator && !validator->validate(id)) {

this control - reqcon.set(controls::ContrastLoHistogram, 0.0);

[naushir]

In gdb, when you hit the error, type frame 1 and look at the output line, then do the same for frame 2.

[Lusifug]

[naushir]

If you have a branch that I could try out (libcamera + application) perhaps I can give it a try and see if I can help. Otherwise it's going to be impossible for me to say what could be going wrong with your changes.

[Lusifug]

I`ve created repo, with my changes. my test program and make file for it is inside "test app" dir https://github.com/Lusifug/libcamera/tree/CE_controls

[naushir]

I'm afraid I get compile errors with that tree:

[naushir]

Are you using the CE_controls branch or the main branch for your build above? From what I gather, the main branch does not have your new controls.

[naushir]

Any updates on this? If not, I'll close it down shortly.
