I didn’t use VLC in my solution, we receive the stream with the Windows Gstreamer library and I have something like 30ms latency with udpsink.
Here is a pipeline that works for me if someone wants to send it to VLC, but I couldn’t get better than 1s latency :
std::string gst_out = "appsrc is-live=1 ! video/x-raw, width=1920, height=1080 ! videoconvert ! timeoverlay valignment=4 halignment=1 ! nvvidconv ! video/x-raw(memory:NVMM), width=1920, height=1080 ! tee name=t ! nvv4l2h265enc EnableTwopassCBR=1 insert-sps-pps=1 idrinterval=15 iframeinterval=1000 bitrate=64000000 vbv-size=1600000 maxperf-enable=1 preset-level=1 ! h265parse ! rtph265pay config-interval=1 pt=96 ! udpsink host=IP.address port=PORTsync=0 async=0 t. ! nvegltransform ! nveglglessink max-lateness=11000 sync=0";
The receiver needs to open a .sdp file to read that stream. Adjusting the bitrate helps suppressing blurred frame.
Thank you DaneLLL for the help.
