OPENCV push stream into RTSP server

[DaneLLL]

Hi,
The high CPU usage is from:

video/x-raw,format=BGRx ! nvvidconv ! nvv4l2h264enc

It actually does

copy BGRx CPU buffer to NVMM buffer -> convert to NV12 NVMM buffer

OpenCV support CPU buffer only, so the memcpy is must-have and cannot be eliminated.
And some usage is from

appsrc ! videoconvert ! video/x-raw,format=BGRx

This is to convert BGR to BGRx through CPU.

There is a similar discussion:

[Gstreamer] nvvidconv, BGR as INPUT

Hello, according to: https://developer.download.nvidia.com/embedded/L4T/r32_Release_v1.0/Docs/Accelerated_GStreamer_User_Guide.pdf nvvidconv allows BGRx as input but not BGR, have you considered to add this format? In this way is not required to use videoconvert and use CPU. I request this info why my application: capture frame from RTSP and convert it to BGR detect objects edit frame with OpenCV write frame to nvdrmvideosink In step 4 I use this code (python): send_gst = "appsrc ! vide…
