Hi Andy, Check this link. GStreamer Transcoding and Scaling.

Thank you Leo,

I tried to follow command:

mx6q send:

modprobe ov5642_camera

modprobe mxc_v4l2_capture

gst-launch -v --gst-debug=vpuenc:4 mfw_v4lsrc capture-mode=1 \

! video/x-raw-yuv,framerate=25/1 \

! vpuenc codec=6 \

! udpsink host=192.168.3.113 port=2011

PC ubuntu:

gst-launch -vvv --gst-debug=3 udpsrc port=2011 \

caps ="video/x-h264, width=(int)320, height=(int)240, framerate=(fraction)25/1, framed=(boolean)true" \

! ffdec_h264 \

! ffmpegcolorspace \

! videoscale \

! xvimagesink sync=false

On PC ubuntu the video receiving is right.

when I tried follow command:

mx6q send:

modprobe ov5642_camera

modprobe mxc_v4l2_capture

gst-launch -v --gst-debug=vpuenc:4 mfw_v4lsrc capture-mode=3 \

! video/x-raw-yuv,framerate=25/1 \

! vpuenc codec=6 \

! udpsink host=192.168.3.113 port=2011

PC ubuntu:

gst-launch -vvv --gst-debug=3 udpsrc port=2011 \

caps ="video/x-h264, width=(int)720, height=(int)576, framerate=(fraction)25/1, framed=(boolean)true" \

! ffdec_h264 \

! ffmpegcolorspace \

! videoscale \

! xvimagesink sync=false

On PC ubuntu the video not display.

the debug info:

imx6q send:
