Hi, I have tried the python DASH client and it is amazing. The example works in the beginning but the windows will freeze with some blurred block as the figure shows when the resolution is changed but the terminal prints logs as normal.  I wonder to know how to fix it.  The libgpac version is `gpac-1.1.0-DEV-rev770-gc8edcaff-master-x64` and the OS is windows 10.

The second question is I want to do some processes of the frames such as scaling the frame or draw a rectangle in the frame after decoding the video and get the numpy array while disabling the playing window. After reading the document in the wiki, it seems that I need a custom filter but I can not run the example in the wiki and determine the position of the filter in the workflow. Would you mind providing an example more detailedly?

Thanks for your help.
