RZ-G

Examples for RZ/G2L

Down Scaling using vspmfilter

  • Below table show range of support:
Supported solution range
Input resolution Output scale down ratio
Min 128x72 1
Max 1920x1080 15

Following are sample commands for Up/Down Scaling with h264 Elementary Stream file.

Case of Down Scaling

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, format=BGRA, width=1280, height=720 ! waylandsink

Case of Down Scaling (without color format conversion)

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, width=1280, height=720 ! waylandsink

Case of Down Scaling (without color format conversion – use dmabuf)

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter dmabuf-use=true ! video/x-raw, width=1280, height=720 ! waylandsink

Color format conversion using vspmfilter

  • Below table show color format conversion using vspmfilter:
Supported color format
No. Supported color format
1 BGRA
2 BGRx
3 RGB16
4 YUY2
5 NV12

Following are sample commands for converting color format. Please set the output format which begin supported following “format=”.

Case of BGRA output

gst-launch-1.0 filesrc location=filename.mp4 ! qtdemux ! queue ! h264parse ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, format=BGRA ! waylandsink

Examples for RZV2L

Camera Setup

This section describes how to setup the RZV2L Camera module OV5645.

Camera Setup VGA

media-ctl -d /dev/media0 -r ;

media-ctl -d /dev/media0 -l "'rzg2l_csi2 10830400.csi2':1 -> 'CRU output':0 [1]" ;

media-ctl -d /dev/media0 -V "'rzg2l_csi2 10830400.csi2':1 [fmt:UYVY8_2X8/640x480 field:none]" ;

media-ctl -d /dev/media0 -V "'ov5645 0-003c':0 [fmt:UYVY8_2X8/640x480 field:none]" ;

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! waylandsink

Camera Setup 720p

media-ctl -d /dev/media0 -r ;

media-ctl -d /dev/media0 -l "'rzg2l_csi2 10830400.csi2':1 -> 'CRU output':0 [1]" ;

media-ctl -d /dev/media0 -V "'rzg2l_csi2 10830400.csi2':1 [fmt:UYVY8_2X8/1280x720 field:none]" ;

media-ctl -d /dev/media0 -V "'ov5645 0-003c':0 [fmt:UYVY8_2X8/1280x720 field:none]" ;

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! waylandsink

Down Scaling using vspmfilter

Down Scale Camera 720p video

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! vspmfilter dmabuf-use=true ! video/x-raw, width=640, height=480 ! waylandsink

Down Scale H264 Video File

gst-launch-1.0 filesrc location=./in720p.mp4 ! qtdemux ! queue ! h264parse ! queue ! omxh264dec ! queue ! ! vspmfilter dmabuf-use=true ! video/x-raw, width=640, height=480 !waylandsink

Create H264 Video File

This script can be run on the RZV2L

gst-launch-1.0 videotestsrc ! omxh264enc ! filesink location=./testvideo.h264

Stream H264 Video Over IP

RZV2L(Source) Device send h264 stream using RTP:

Set the IP address to the PC or device that receives the video

gst-launch-1.0 -v v4l2src device=/dev/video0 ! videoconvert ! vspmfilter dmabuf-use=true ! video/x-raw, width=640, height=480 ! queue ! omxh264enc ! queue ! rtph264pay ! queue ! udpsink host=<PC IP Address> port=5000

PC that receives h264 rtp stream:

gst-launch-1.0 -v udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! autovideosink

PC receives H264 RTP Stream with VLC Player:

1) Create a SDP script file ( i.e. test.sdp ).

2) Add the following to the file. The variable IP_ADDR_HOST_VID needs to be changed to the device (RZV2L) that is hosting the video.

c=IN IP4 IP_ADDR_HOST_VID

m=video 5000 RTP/AVP 96

a=rtpmap:96 H264/90000

3) Run the following Command

vlc --avcodec-hw=vaapi test.sdp
