Hello all,
I am trying to decode a H264 rtsp stream expoiting NVCUVID via GStreamer.
My GPU card is NVIDA RTX 2080.
I ultimately need to decode frames and have access to raw rgb data form CPU
for further image processing.
I built Gstreamer 1.16 with Cerbero since the nvdec plugin is not
available on my stock distro (Ubuntu 18.04 LTS). The best pipeline that I managed to put toghether is:
gst-launch-1.0 rtspsrc location="rtsp://root:root@192.168.0.91:554/axis-
media/media.amp?videocodec=h264&resolution=3840x2160&fps=25"
protocols=GST_RTSP_LOWER_TRANS_TCP latency=0 ! rtph264depay ! h264parse !
nvdec ! gldownload ! fpsdisplaysink sync=false
The problem: this pipeline shows only completely green frames but the fps counter increases, the
framerate is consistent with the camera fps and nvidia-smi shows that the
process is using some gpu memory.
Anyone has an idea about how to fix it?
