I tried using phonon to play the video but could not succeed. Off-late came to know through the Qt forums that even the latest version of Qt does not support phonon. Thats when i started using Gstreamer.Any suggestions as to how to connect the Gstreamer window with the Qt widget?My aim is to play a video using Gstreamer on the Qt widget.So how do i link the gstreamer window and the Qt widget?
I am successful in getting the Id of the widget through winid().
Further with the help of Gregory Pakosz, I have added the below 2 lines of code in my application -
QApplication::syncX();
gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(sink), widget->winId());
However am not able to link the Qt widget with the gstreamer video window.
This is what my sample code would look like :-
int main(int argc, char *argv[])
{
printf("winid=%d\n", w.winId());
gst_init (NULL,NULL);
/* create a new bin to hold the elements */
bin = gst_pipeline_new ("pipeline");
/* create a disk reader */
filesrc = gst_element_factory_make ("filesrc", "disk_source");
g_assert (filesrc);
g_object_set (G_OBJECT (filesrc), "location", "PATH_TO_THE_EXECUTABLE", NULL);
demux = gst_element_factory_make ("mpegtsdemux", "demuxer");
if (!demux) {
g_print ("could not find plugin \"mpegtsmux\"");
return -1;
}
vdecoder = gst_element_factory_make ("mpeg2dec", "decode");
if (!vdecoder) {
g_print ("could not find plugin \"mpeg2dec\"");
return -1;
}
videosink = gst_element_factory_make ("xvimagesink", "play_video");
g_assert (videosink);
/* add objects to the main pipeline */
gst_bin_add_many (GST_BIN (bin), filesrc, demux, vdecoder, videosink, NULL);
/* link the elements */
gst_element_link_many (filesrc, demux, vdecoder, videosink, NULL);
gst_element_set_state(videosink, GST_STATE_READY);
QApplication::syncX();
gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(videosink), w.winId());
/* start playing */
gst_element_set_state (bin, GST_STATE_PLAYING);
}
Could you explain more in detail about the usage of gst_x_overlay_set_xwindow_id() wrt my context?
Could i get any hint as to how i can integrate gstreamer under Qt?
Please help me solve this problem
