Reading streaming video frame by frame

[omer.tal]

Hello again,

So your issue was the return type of the callback:

    //signal handling function
static GstFlowReturn new_sample (GstElement *sink, CustomData *data){
      printf("Hello\n");
      printf("frame signal\n");
      GstSample *sample;
      GstBuffer *buf;
      g_signal_emit_by_name(sink,"pull_sample",&sample);
      buf=gst_sample_get_buffer(sample);
//      printf("%c\n",buf[0]);
      if(sample){
        gst_sample_unref(sample);
	return GST_FLOW_OK;
      }
    return GST_FLOW_ERROR;
    }


Hope this works for you. I've tested your program with a sample pipeline and
it worked for me.
