I managed to get working the following configuration under L3.0.35_4.1.0 Linux (demo, oneiric  FileSystem) :

On i.MX6 SDP target (as an example) :

$ ifconfig eth8 192.168.1.114

$ route add default gw 192.168.1.1                 # local server

$ echo nameserver 8.8.8.8 >> /etc/resolv.conf  # if I-net is needed

$ modprobe ov5642_camera

$ modprobe mxc_v4l2_capture

$ gst-launch mfw_v4lsrc capture-mode=4 ! vpuenc codec=12 ! tcpserversink host=192.168.1.113  port=5000

(My Windows PC host IP=192.168.1.113)

On Windows PC, under VLC, configure source as tcp://192.168.1.114:5000

Hi Muhin,

Thanks for valuable input now got streaming over RTP as followed your post.

One question want ask to you without vlc, camera streaming could possible or not ?

Second through gst sender command gst-launch mfw_v4lsrc capture-mode=4 ! vpuenc codec=12 ! tcpserversink host=192.168.1.113  port=5000

could send audio data also ?

Thanks,

Vidya

Without VLC :

on other side, as an example :

gstlaunch tcpclientsrc host=192.168.1.114 port=5000 ! vpudec ! autovideosink

2.

As for audio - did not try yet myself.
The next thread GStreamer RTP Streaming states about audio too.

Hi Muhin,

Whenever i run gst-launch tcpclientsrc host=192.168.1.114 port=5000 ! vpudec ! autovideosink

client ubuntu PC through WARNING: erroneous pipeline: no element "vpudec"

because vpudec not installable package in ubuntu12.04 so how could stream without VLC.

If you have any idea video streaming with audio please suggest me.

I am able to record audio file arecord -f dat -d 10 -D hw:0,0 test.wav

and playback through

aplay -f dat test.wav

Please suggest me combined pipeline to get audio and video streaming over Ethernet.

Thanks,

Vidya

This is correct - no element "vpudec" - since vpudec is used with i.MX6 VPU ; for PC case
we can apply to a standard software decoder, which - of course - should correspond other side encoder.
Please use "gst-inspect" command to review what decoders are included in Your Ubuntu on PC.
