I'm trying to use the demo provided with the VSDK inside a Yocto build (18) and the demo named gdc_pd.elf is giving me problems;
I want to change the configuration so that the input comes from the camera (Sony imx224), but if I set the variable WeUseFileReader to zero in the configuration file data/apps/pedestrian_detection/gdc_pd.ini, the demo crashes with a SEGFAULT.
Using a debugger seems that the problem comes from the line 138 of the file gdc_pd_image_sensor_task.cpp, i.e. at the instruction DdrBufferDescSet(), probably a NULL pointer.
I successfully changed other parameters in the same configuration file (like WeRotateDisplay) and that has not given any problem.
I have the same result with pedestrian_detection demo. The pedestrian_detection_aggcf works okay with camera.
I'll contact Vision team if they have solution for the gdc_pd.elf demo.
