Gstreamer Giving Bad GC errors.

Hi,

I have written a GUI application, which reads from a given filesystem and displays pictures in a QT Window. Here I am using Gstreamer, Playbin pipeline, XImageSink for video sink element. And every time I am calling gst_x_overlay_set_xwindow_id() function to pass my QT window handle to the Gstreamer Playbin in my bus watcher function. After receiving EOS of each picture the pipeline is paused so that user can select Next or Prev buttons to navigate the picture filesystem.

But after clicking Next/Prev 4-5 times my application is crashed and it is giving BadGC (Invalid GC parameter) error. I couldn’t figure out why it is coming.

Any help is appreciated.

Regards,

Deb

setAttribute(Qt.WA_NativeWindow)

on the video widget, this solved the issue for me,

Re: Gstreamer Giving Bad GC errors.

Thanks Nicole for your reply. I tried WA_NativeWindow but still getting Bad GC and application crashing. But before application crashed after 5-6 Next/Prev, now it crashes after 10-12 clicks on Next/Prev button.

I cannot reproduce the error in my player, do you use set_xwindow_id when you
receive the prepare-xwindow-id message on the bus?

Re: Gstreamer Giving Bad GC errors.

Actually, I am calling
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (GST_MESSAGE_SRC (msg)),
window_id)

when I am receiving this GST_IS_X_OVERLAY(GST_MESSAGE_SRC (msg)) in the
bus.

My implementation is in python not in c, here is the relevant code:

message_name = message.structure.get_name()
if message_name == "prepare-xwindow-id":
imagesink = message.src
imagesink.set_property("force-aspect-ratio", True)
imagesink.set_xwindow_id(self.xid)

where self.xid is:

self.xid=self.ui.widgetVideo.winId()

defined in the widget init.

I tested my application doing at least 50 Next/Prev with no crash, so I think
is something in your code and not a gstreamer or qt problem,

good luck,

Nicola
