Issue Description

Hi

I'm aving problems using pyrealsense and PyQt5, the following code:

import sys
import pyrealsense2 as rs
from PyQt5.QtWidgets import QApplication

if __name__ == "__main__":
    app = QApplication(sys.argv)
    sys.exit(app.exec_())

produces this error:

QWindowsContext: OleInitialize() failed: "COM error 0xffffffff80010106 RPC_E_CHANGED_MODE (Unknown error 0x080010106)"

The pyqt application opens (when there is one in the code) but crashes when trying to do any action.
I tried the solution suggested here in this way

import warnings
warnings.simplefilter("ignore", UserWarning)
sys.coinit_flags = 2
import pyrealsense2 as rs

but it did't work in my case.

Thank you.

Hi @dguari1,

Per my observation:
Although the error there, realsense camera can be still enabled to stream, right?

The code I tried as follows:

**import** sys
**from** PyQt5.QtWidgets **import** QMainWindow , QApplication
**from** PyQt5.QtGui **import** QIcon
**import** pyrealsense2 **as** rs

**class** MainWidget(QMainWindow):
 **def** __init__(self,parent=**None**):
 super(MainWidget,self).__init__(parent)
 self.setWindowTitle(**"QMainWindow Example"**)
 self.resize(400, 200)
 self.status = self.statusBar()
 self.status.showMessage(**"Status"**,5000)

 **def** enableRSCamera(self):
 _# Configure depth and color streams_
 self.pipeline = rs.pipeline()
 self.config = rs.config()
 _# Start streaming_
 profile = self.pipeline.start()


**if** __name__ == **"__main__"**:
 app = QApplication(sys.argv)
 app.setWindowIcon(QIcon(**"./images/cartoon1.ico"**))
 main = MainWidget()
 print(**'Test...'**)
 main.show()
 main.enableRSCamera()
 print(**'Enabe RSCamera'**)
 sys.exit(app.exec_())

Thx for replying.
The PyQt window does appear, but the program freezes immediately and crashes after a few seconds

Actually I created a PyQt5 application, with the same error notice, but mine runs just fine

one is to import it in the function in a multiprocess pool function
https://github.com/soarwing52/RealsensePython/blob/master/proccessor.py
this does not show any error because I suppose it's imported in the Pool

another is a camera control application, this imports in a thread
https://github.com/soarwing52/RealsensePython/tree/master/qtcam
this also has the error but everything works fine

Importing pyrealsense locally solved the issue, thank you @soarwing52
