= Encode videotest pattern in H.264 (without container)
gst-launch-1.0 videotestsrc num-buffers=1000 ! omxbufferalloc num-buffers=8 ! omxh264enc ! perf print-arm-load=true ! filesink location=sample.h264

V4l2 Capture and recording
gst-launch-1.0 v4l2src io-mode=3 device=/dev/video0 num-buffers=1000 ! 'video/x-raw,format=(string)NV12,width=1280,height=720,framerate=(fraction)60/1' ! perf print-arm-load=true ! omxbufferalloc num-buffers=12 -v ! omxh264enc i-period=30 idr-period=30 ! queue ! rrh264parser single-nalu=true ! mp4mux dts-method=0 ! filesink location=test_v4l2src_1.0.mp4
V4l2 Capture and UDP streaming
You have to set HOST and PORT variables to your own
gst-launch-1.0 v4l2src io-mode=3 device=/dev/video0 ! 'video/x-raw,format =(string)NV12,width=1280,height=720,framerate=(fraction)60/1' ! perf print-arm-load=true ! omxbufferalloc num-buffers=12 ! omxh264enc i-period=30 idr-period=30 ! mpegtsmux ! udpsink host=$HOST port=$PORT sync=false async=false
Later you could get the stream in your host side
gst-launch-1.0 udpsrc port=$PORT ! tsdemux ! fakesink -v
