I have 2 applications. One application (application A) creates a window, and
sends the window ID to another application (application B). application B
has a gstreamer video pipeline that uses xvimagesink to display the video as
overlay in the window using the window ID provided by application A. I am
sorry if it sounds a little confusing. This is to separate UI from pipeline.
Following function is used to configure xvimagesink with window ID:
Most of time it works fine, but sometimes I encounter the following problem,
and the application B is terminated:
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 3 (X_GetWindowAttributes)
Resource id in failed request: 0x400016f
Serial number of failed request: 32
Current serial number in output stream: 33
After some debugging, I found the error was generated in function
gst_xvimagesink_set_xwindow_id() when it called the following function:
Could anyone give some hint how to fix this problem?
