Hi Kirill,

I'm not the op but I tried your patch and it failed with the following 
against a Windows 11 machine:

[13:35:13:684] [85250:182a9e40] [ERROR][com.freerdp.core] - 
transport_read_layer:freerdp_set_last_error_ex 
ERRCONNECT_CONNECT_TRANSPORT_FAILED [0x0002000D]
xfreerdp:/usr/local/lib/libfreerdp2.so.3.0: undefined symbol 'avcodec_close'
ld.so: xfreerdp: lazy binding failed!
Killed

But successfully connected to an Ubuntu machine running xrdp.

Cheers

Fred
