Hi, I’ve built freerdp (very recent master) with options -DWITH_SSE2=ON 
-DWITH_SERVER=ON. On windows 10.

I run the server with just the port:xxxx argument, and wfreerdp with just 
/v:host:port.

Bandwidth usage seems a bit high, but not much different than Microsoft rdp 
client/server while watching a similar scrolling window.

I assume that turning on H.264 would help with bandwidth usage.

I've been poking around in code and debugger to figure out when H264 gets used 
and found it does with /GFX-H264 on the client command line.

When I use this setting, the server side crashes shortly after it sends a few 
frames in some memcpy operation.  Call stack doesn't help at that point 
(different thread with memcpy as only frame)

I also tried with /GFX-H264:AVC420 (which I think it used by default with just 
GFX-H264) as well as :AVC444, but that also crashed.  I did validate in the 
debugger that it was actually calling the avc420_compress as well as 
avc444_compress when I specified those options on the client.

Anyone else have any luck with these options?

Any hints to figure out what's going on?

My setup is using 2 Windows 10 VMs running on VMWare fusion 10.1.2.
