How to stream out two pipelines?

[Erickson.LU]

Hi Nicolas,
    I  want to stream out two pipelines with GStreamer.
push2nabble.cpp
<http://gstreamer-devel.966125.n4.nabble.com/file/t378216/push2nabble.cpp>  
Here is the code, I created want to create two different GstPipeline. But I
use    
*gst_init(NULL, NULL); 
loop = g_main_loop_new(NULL, FALSE);*
twice.

Here is the code I used in Main 

*    char pipeline_char0[MAX_PIPELINE_STR_LEN];
    char pipeline_char1[MAX_PIPELINE_STR_LEN];

    sprintf(pipeline_char0, Tx2_test_3220, Stream_BGR_width,
Stream_BGR_height, Stream_OUT_width, Stream_OUT_height);
    sprintf(pipeline_char0, Tx2_test_3221, Stream_BGR_width,
Stream_BGR_height, Stream_OUT_width, Stream_OUT_height);
    Gst_handle0 *gst_handle0 = new Gst_handle0(pipeline_char0);
    Gst_handle1 *gst_handle1 = new Gst_handle1(pipeline_char1);
    gst_handle0->start_stream();
    gst_handle1->start_stream();
    while (active) {
            gst_handle0->push_out_UYVY(v4l2_cam->fbuffer);
           
gst_handle1->push_out_UYVY(v4l2_cam->fbuffer+Stream_BGR_width*Stream_BGR_height*2*1);
    }

Here is the log from terminal.

Please give me some hints, reason or advice, thanks for that, Nicolas, you
are the best.
