For me, just use vision_apps testcase, the name for testcase is app_ldc, I choose a png file just for 1280*720 grayscale image.
Modify input filepath and filename, output filepath and filename, then running the demo, I found no error happened because
APP_ASSERT is used for check returned value. When returned value is not VX_SUCCESS, the demo would be broken.
However, the output file didn't exist in output filepath. The demo was on A72 arm core to run and compiled by cross compiler.
I want to know the reason why save png file by tivx_utils_load_vximage_from_pngfile write failed.
