I am trying to run a deepstream application on my device. I get following issue while running my application with my current rtsp.
NVPARSER: HEVC: Seeking is not performed on IRAP picture
I have tested my rtsp with multiple methods. It is working only with cv2 with ffmpeg as a backend with other methods it is giving errors.
