Can't load .jpg images when using ofxKinectV2

[Kauã Melo]

Thank you very much for the addon, Theo!

I came across the following issue. I can't open a .jpg image if I have ofxKinectV2 in the addons.make file. Loading .png works fine.

addons.make

ofxKinectV2 <- Remove this to be able to load .jpg

ofApp.h

#include "ofxKinectV2.h" //  comment this to be able to load .jpg
...
    ofImage bImg;

ofApp.cpp

...
void ofApp::draw()
{
    if (bImg.isAllocated())
    {
        bImg.draw(0, 0);
    }
}
...
void ofApp::dragEvent(ofDragInfo dragInfo)
{
    bImg.load(dragInfo.files[dragInfo.files.size() - 1]);
    cout << "Path: " << dragInfo.files[dragInfo.files.size() - 1] << endl;
    cout << "Dimensions: " << bImg.getWidth() << "x" << bImg.getHeight() << endl;
}

When I run the code above and drag a .jpg onto the canvas, I get the following on the terminal:

[ error ] ofImage: loadImage(): couldn't load image from ""/Users/kaua/Desktop/asd.jpg""
Path: /Users/kaua/Desktop/asd.jpg
Dimensions: 0x0

I'm using of_v0.10.1_osx_release on macOS 10.14.4.

Thanks for this report. Will test this out.
I wonder if this is due to the addition of libturbojpeg conflicting with freeimage in some way.

[Nick Hardeman]

Just tested this on OSX with an app built with the project generator and was able to load both jpg and png. As Theo mentioned, libturbojpeg could be interfering if it's added to Xcode or the lib is linked. That lib is not needed on OSX. If it's added try removing it and see if that fixes it.

[Theodore Watson]

Hmm weird - I am on macOS 10.14.6 and also can't recreate this issue.
I even tried dragging both libturbojpeg libs into the project.

Are you using Xcode or another environment / make files?

[Kauã Melo]

Hey, thanks for the super fast response.

That's weird, I'm not sure what I'm missing here.
Here's what I just tried:

• downloaded OF of_v0.10.1_osx_release and ofxKinectV2 again.
• pasted ofxKinectV2 in the addons folder.
• duplicated the emptyExample and renamed it.
• Pasted the code I described above.
• From the Visual Studio Code terminal:

$ make
$ make RunRelease

As Nick suggested, I also tried to remove libturbojpeg. I only found mentions to it under addons/ofxKinectV2/addon_config.mk, so I commented these lines:

    #ADDON_INCLUDES_EXCLUDE  = "libs/libturbojpeg"
    #ADDON_INCLUDES_EXCLUDE  += "libs/libturbojpeg/%"

but I still have the same issue.

When I check the obj/osx/Release/.compiler_flags file after compiling the code, I can see the following mentions to libturbojpeg:

-I/Users/kaua/Documents/of_v0.10.1_2/addons/ofxKinectV2/libs/libturbojpeg
-I/Users/kaua/Documents/of_v0.10.1_2/addons/ofxKinectV2/libs/libturbojpeg/include
-I/Users/kaua/Documents/of_v0.10.1_2/addons/ofxKinectV2/libs/libturbojpeg/lib

-I/Users/kaua/Documents/of_v0.10.1_2/addons/ofxKinectV2/libs/libturbojpeg/lib/ios

When I remove the ofxKinectV2 from the addons.make file, there are no mentions to libturbojpeg in obj/osx/Release/.compiler_flags and the code works fine.

So apparently ofxKinectV2 is still making usage of libturbojpeg somehow? Do you guys have the same flags when using ofxKinectV2? Do you have any suggestion on how can we avoid that?

[Theodore Watson]

So looks like a vscode / makefile quirk as Xcode doesn't seem to have these issues.

Either way the ADDON_INCLUDES_EXCLUDE should be excluding the files.

That might be the project generator not picking up the includes correctly.
This might be fixed in the nightly build of OF here: https://openframeworks.cc/download/

If you delete this folder all together from Finder does it build and run okay?
addons/ofxKinectV2/libs/libturbojpeg/lib

[Kauã Melo]

Good news!

Deleting the folder addons/ofxKinectV2/libs/libturbojpeg/lib seems to solve the problem.
It loads .jpg now with no errors.

I think the issue might be with makefile since I get the same problem when I'm using the Terminal.

Thank you very much Theo, I appreciate the fast responses! You work is really inspiring.
