to control tee plugin

[sun.wenmao at furuno-dl.com (sunwenmao)]

Hi,

I want to modify the plugin-tee in gstreamer in some details! In the function
of the file gsttee.c in gstreamer-0.10.19: 

static GstFlowReturn gst_tee_handle_buffer (GstTee * tee, GstBuffer * buffer)

 I plan to add two pads ?src0 and src1?in order to control any one of them
to output datas!  So I write some codes as follows: 

             if( strcmp(pad_name, "src0") == 0 )     

                 ret = gst_tee_do_push (tee, pad, buffer); }

             else

                 ret = GST_FLOW_OK;  //do nothing

But when I input the instruction like this: gst-launch v4l2src ! tee name=t t.
! queue ! filesink location=./test1.yuv t. ! queue ! filesink location=./test2.yuv

in davinci DM6446, both of the two video files are empty! I don?t know the
reason and search for some information on Internet all the time, but no
results! So I really 

want to know weather the tee plugin can control any one of the two pads
separately! Hope someone can help me! 

Thanks very much!
