access violation problem when using MSDrawDibDisplay video filter of linphone sdk 5.3.57

Hi,
When using C# winform PictureBox control to show video in windows 10, I encountered a problem. It crashed and the message is this:


Unhandled exception at 0x1AA61920 (yuv.dll) in CPFCcodSipPhone.exe.14200.dmp: 0xC0000005: Access violation writing location 0xFFFFF880.


I am using MSDrawDibDisplay video filter, it works in linphone 4 sdk, but when updated to linphone 5 sdk, it crashed.


The code is like this:


Core.VideoDisplayFilter = "MSDrawDibDisplay";


I didn't find yuv.dll (in the error message) in linphone 4 sdk, maybe it is some new feature.


Can anyone help me sovle this problem? Thanks.
