Hey,
I am trying to do the same thing. My sink is rtmp server.
Issue is when I use streaming to only local it's working fine with below pipe:
gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=4 fps-n=30 ! video/x-raw,width=1280,height=720,framerate=30/1 ! timeoverlay ! imxipuvideosink
When I want to sink it to local + rtmp server, I could see lot of latency and frame drops on local as well. Here is the pipeline that I am using:
gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=4 fps-n=30 ! video/x-raw,width=1280,height=720,framerate=30/1 ! timeoverlay ! tee name="local" local. ! queue ! imxipuvideosink local. ! queue ! imxipuvideotransform ! imxvpuenc_h264 bitrate=8000 ! h264parse ! flvmux ! rtmpsink location=rtmp://192.168.0.56/live
Any clue?
