Gstreamer tkinter x error failed request

[WisdomPill]

I'm trying to display different gstreamer pipelines output in the same window
with tkinter. I tried to create my own Frame that adds the gstreamer
pipeline. I supposed I can subclass 

frames.py

    from tkinter import Frame, NW
    
    import gi
    
    # Needed for set_window_handle():
    gi.require_version('GstVideo', '1.0')
    gi.require_version('Gst', '1.0')
    from gi.repository import Gst, GObject, GstVideo
    
    
    class GstFrame(Frame):
        def __init__(self, gst_launch_string, x, y, width, height,
master=None, cnf=dict(), **kwargs):
            super(GstFrame, self).__init__(master=master, cnf=cnf, **kwargs)
    
            self.place(relx=x, rely=y, anchor=NW, relwidth=width,
relheight=height)
    
            self.frame_id = self.winfo_id()
    
            self.player = Gst.parse_launch(gst_launch_string)
            self.player.set_state(Gst.State.PLAYING)
    
            self.bus = self.player.get_bus()
            self.bus.enable_sync_message_emission()
            self.bus.connect('sync-message::element', self.set_frame_handle)
    
        def play(self):
            self.player.set_state(Gst.State.PLAYING)
    
        def set_frame_handle(self, bus, message):
            if message.get_structure().get_name() ==
'prepare-window-handle':
                frame = message.src
                frame.set_property('force-aspect-ratio', True)
                frame.set_window_handle(self.frame_id)
    
    
    class SensorStreamFrame(GstFrame):
        def __init__(self, stream, master=None, cnf=dict(), **kwargs):
            gstreamer_launch_string = 'tcpclientsrc host={} port={} !
gdpdepay ! '\
                                      'rtph264depay ! avdec_h264 !
videoconvert ! '\
                                      'autovideosink
sync=false'.format(stream.host, stream.port)
    
            x = stream.x
            y = stream.y
            width = stream.width
            height = stream.height
    
            super(SensorStreamFrame, self).__init__(gstreamer_launch_string,
x, y, width, height, master, cnf, **kwargs)

utils.py
    from lib.frames import SensorStreamFrame
    
    
    def init_players(streams, window):
        for stream in streams:
            SensorStreamFrame(stream, window)


I get two kinds of error like 

    X Error of failed request:  BadDrawable (invalid Pixmap or Window
parameter)
      Major opcode of failed request:  150 (XVideo)
      Minor opcode of failed request:  19 ()
      Resource id in failed request:  0x5200006
      Serial number of failed request:  384
      Current serial number in output stream:  385

and 

    X Error of failed request:  BadDrawable (invalid Pixmap or Window
parameter)
      Major opcode of failed request:  150 (XVideo)
      Minor opcode of failed request:  19 ()
      Resource id in failed request:  0x5200006
      Serial number of failed request:  536
      Current serial number in output stream:  537

I don't know where to begin debugging this, and lots of research on google
didn't help. Can someone help me or explain what this error is?
