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.

These are due to programming error on your end, wrong type or dead object (no more ref) being used. Best way to locate the problem is to set the following env:
export G_DEBUG=fatal_criticals
Then run your program inside gdb, it will abort instead of doing crash avoidance. Same can be done for warnings, with fatal_warnings.

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