Introduction

DM81xx

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

Scale the QVGA video test pattern to VGA

gst-launch-1.0 videotestsrc num-buffers=1000 ! 'video/x-raw,format=(string)NV12,width=320,height=240,framerate=(fraction)60/1' ! omxbufferalloc num-buffers=8 ! omxscaler  ! 'video/x-raw,format=(string)YUY2,width=640,height=480,framerate=(fraction)60/1' ! perf print-arm-load=true ! fakesink

DM8148

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

These instructions show how to do video streaming over the network, a video will be captured on the board and viewed on the host. These pipelines use the port that you configure to send the packets. To configure the port and the host ip to send the streaming you have to set the variables port=$PORT and host=$HOST to your own).

  • Server: DM81xx

Set the variables HOST and PORT to your own, for example:

HOST=10.251.101.43
PORT=3001

And run the pipeline:

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
  • Client: Ubuntu PC

Set the same port configured in the server:

PORT=3001

And run the pipeline:

gst-launch-1.0 udpsrc port=$PORT ! tsdemux ! h264parse ! avdec_h264 ! xvimagesink sync=true async=false
