I am not able to stream video in hw Raspberry Pi 4 Model B Rev 1.5. I am using sample code kvsWebrtcClientMasterGstSample.c and I modified only pipeline code. please find below.

PVOID sendGstreamerAudioVideo(PVOID args) function inside

            case DEVICE_SOURCE: {
                senderPipeline = gst_parse_launch(
                    "v4l2src device=/dev/video0 ! queue ! v4l2convert !"
		"video/x-raw,width=640,height=480,framerate=30/1 !"
		"v4l2h264enc !"
                    "h264parse !"
                    "video/x-h264,stream-format=byte-stream,alignment=au,width=640,height=480,framerate=30/1,profile=baseline,level=(string)4 !  "
                    "appsink sync=TRUE emit-signals=TRUE name=appsink-video",
                    &error);

Are you using the camera module as your camera? If so you should be using libcamerasrc instead of v4l2src.

Refer to https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producersdk-cpp-rpi-run.html

Could you share the output of gst-device-monitor-1.0 Video/Source?

You might be able to get something working by replacing the v4l2convert with videoconvert.
