On this page you are going to find a set of pipelines used on the DM8168 (EVM and Z3 boards) and DM8148 (EVM). It's important to mention that some of these pipelines are documented twice in the first section of this page, the first one is to be run on the Z3 board and the second one to be used on the DM8168-EVM board, the main difference between them is the absence of the omx_tvp element which performs the initialization of the TVP7002 hardware in order to capture video from the component input on the EVM board. This element is not needed on the Z3 board, since Z3 has created an initialization script called init_7611_edid.sh which performs the hardware initialization for both, the TVP7002 and the ADV7611 to capture from HDMI inputs. Moreover, the second section of this page contains pipelines to be used on DM8148 with the RidgeRun SDK, on this section you will find pipelines to display video on the HDMI port as well as on the LCD that is built in with the DM8148-EVM

Some of these pipelines have to be run on the target board and other in your computer, they are distinguished by the color used to document them, blue pipelines are for the Z3 board, yellow for EVM board and green pipelines have to be run in your PC

These instructions show how to do video streaming over the network, a video will be played on the board and viewed on the host. These pipelines use the default port (4951) to send the packets, if you want to change the port number, you have to add the port capability to the udpsink.(e.g udpsink port=$PORT host=$CLIENT_IP)

Introduction

On this page you are going to find a set of pipelines used on the DM8168 (EVM and Z3 boards) and DM8148 (EVM). It's important to mention that some of these pipelines are documented twice in the first section of this page, the first one is to be run on the Z3 board and the second one to be used on the DM8168-EVM board, the main difference between them is the absence of the omx_tvp element which performs the initialization of the TVP7002 hardware in order to capture video from the component input on the EVM board. This element is not needed on the Z3 board, since Z3 has created an initialization script called init_7611_edid.sh which performs the hardware initialization for both, the TVP7002 and the ADV7611 to capture from HDMI inputs. Moreover, the second section of this page contains pipelines to be used on DM8148 with the RidgeRun SDK, on this section you will find pipelines to display video on the HDMI port as well as on the LCD that is built in with the DM8148-EVM

Please be sure to run the init_7611_edid.sh script before to run pipelines to capture video (if you are using the Z3 board), also you will need to disable the graphics plane before to run pipelines to display video:

./init_7611_edid.sh
echo 0 > /sys/devices/platform/vpss/graphics0/enabled

Some of these pipelines have to be run on the target board and other in your computer, they are distinguished by the color used to document them, blue pipelines are for the Z3 board, yellow for EVM board and green pipelines have to be run in your PC

DM81xx

Display videotest pattern

gst-launch -v videotestsrc ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60  ! gstperf ! omx_videosink sync=false

Scale the QVGA video test pattern to VGA

gst-launch -v videotestsrc ! 'video/x-raw-yuv,width=320,height=240' ! omx_scaler ! \
'video/x-raw-yuv,width=640,height=480' ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! \
gstperf ! omx_videosink sync=false -v

Encode videotest pattern in H.264 (without container)

gst-launch -v videotestsrc num-buffers=1000 ! omx_h264enc ! gstperf ! filesink location=sample.264

Video Streaming

These instructions show how to do video streaming over the network, a video will be played on the board and viewed on the host. These pipelines use the default port (4951) to send the packets, if you want to change the port number, you have to add the port capability to the udpsink.(e.g udpsink port=$PORT host=$CLIENT_IP)

RTP

Stream H.264 video test pattern over RTP

CLIENT_IP=10.251.101.58

gst-launch videotestsrc ! omx_h264enc ! queue ! h264parse !  gstperf ! rtph264pay ! udpsink host=$CLIENT_IP -v

This pipeline is going to print the capabilities of each element's pad thanks to the -v option. The pipeline should print something similar to this output:
