Hi,

 

I am try to stream video data from one LeopardBoard 368 to another LeopardBoard 368, using the Belkin F5D7050A wireless dongle. My problem is that the client's network hang a few seconds after my server code have been executed. Below shows the code I am using.

Thanks for your help.

 

My Server code:

 

PORT=5000

CLIENT_IP=10.42.43.1

 

gst-launch v4l2src always-copy=FALSE ! video/x-raw-yuv,format=\(fourcc\)NV12, width=640, height=480, \

framerate=\(fraction\)30/1 ! queue ! dmaiaccel ! dmaienc_h264 ratecontrol=1 encodingpreset=2 maxbitrate=400000 targetbitrate=200000 ! rtph264pay ! \

udpsink port=$PORT host=$CLIENT_IP

 

 

My Client code:

 

fbset -disable

PORT=5000

 

gst-launch udpsrc port=$PORT ! 'application/x-rtp, media=(string)video, clock-rate=(int)90000, \

encoding-name=(string)H264, profile-level-id=(string)640028, sprop-parameter-sets=(string)"J2QAKK2EC\

SZuIzSQgSTNxGaSECSZuIzSQgSTNxGaSECSZuIzSQgSTNxGaSEFWuvX1+T+vyfXrrVQgq116+vyf1+T69daq0BQHsg\=\,KO48sA\=\=", \

ssrc=(guint)2963543696, payload=(int)96, clock-base=(guint)872346493, seqnum-base=(guint)43276' ! rtph264depay ! \

dmaidec_h264 ! TIDmaiVideoSink accelFrameCopy=true videoOutput=composite videoStd=D1_NTSC

 

 

 

I create a ad-hoc network by editing the file shown below.

At /etc/init.d/network
iwconfig wlan0 mode ad-hoc; 
iwconfig wlan0 essid 'test'; 
iwconfig wlan0 key 0123456789;

At /etc/network/interfaces
auto wlan0
iface wlan0 inet static
address 10.42.43.1
netmask 255.255.255.0
