I am receiving h264 frames of a stream (720x360@30fps) from a camera connected to my PC via USB. I am converting these frames to BGR frames supported in OpenCV. After the conversion, these frames are sent to the local network via UDP using GStreamer in C++. A code snippet is shown below:</div><div><br></div><div dir="ltr" data-setdir="false"><div><div><br></div><div>---------------------------------------</div><div>class VideoServer {</div><div>public:</div><div> VideoServer() {</div><div> std::string pipeline = "appsrc ! video/x-raw,format=BGR ! queue ! videoconvert ! x264enc bitrate=5000 !

Therefore, can someone point me to an efficient pipeline suitable for the above code snippet?</div><div><br></div><div>Thank you for your time and kind support.</div><div><br></div></div><br></div></div></body></html>
