hello everyone,
My DM368 EVM is bought from TI, Linux:2.6.32.17, DVSDK: dvsdk_dm368_4_02_00_06
I have also build the NFS,and i want to capture image from the camera.So i running the DVSDK demo as discrible at http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines#DM365.
uboot like this:
bootargs=console=ttyS0,115200n8 rw dm365_imp.oper_mode=0 video=davincifb:vid0=OFF:vid1=OFF:osd0=480x272x16,4050K mem=60MB vpfe_capture.interface=1 davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=480x272 root=/dev/nfs nfsroot=10.22.74.211:/root/targetfs ip=10.22.74.212:10.22.74.211:10.22.74.211:255.255.255.192
And i execute this command :
gst-launch -e v4l2src always-copy=false num-buffers=1 input-sr
c=camera ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! jpegen
c -e ! filesink location=VGA_jpeg_file03.jpg
The Jpeg file is empty,and displays the error like this below:

after the above error,i must use Ctrl+c to stop the processing.
Question:1. How can i solve this problem? 2.What can i refer to in transmiting the data from camera to remote computer by internet?
thank you in advance,please help me....
