I use nvivafilter with nvsample_cudaprocess.cu to overlay fixed text on jetson nano camera frames. But How can I do it for dynamic textoverlay which is readen from a text file?
I can’t use gstreamer textoverlay plugin because of high resource cpu.
In fact I wanna read a sensor data by uart and show data on every frame of camera. for reading uart data from serial port I need a while loop in nvsample_cudaprocess.cu file But it makes the camera image stoped and after showing first frame it stops and This is shown in jetson terminal :
