Tool/software:
using g_object_set to set the tiscaler roi paramater. when i update the roi area every 1 second.
the roi area will not changed. please share the reason why the problem. the function will be called every 1 second
here is the code below:
void updateRoiElement(int x,int y ,int width ,int height){
// printf("#########################%d\n",y);
gst_element_set_state(m_pipeline, GST_STATE_PAUSED);
// gst_element_set_state(elementscaler, GST_STATE_PAUSED);
g_object_set(elementscaler, "roi-startx", x,NULL);
g_object_set(elementscaler, "roi-starty", y,NULL);
g_object_set(elementscaler, "roi-width", width,NULL);
g_object_set(elementscaler, "roi-height", height,NULL);
// GstPad *sink_pad = gst_element_get_static_pad(elementscaler, "sink");
// if (sink_pad) {
// gst_pad_send_event(sink_pad, gst_event_new_reconfigure());
gst_element_set_state(m_pipeline, GST_STATE_PLAYING);
}
