Thanks, I stumbled across that code last night. I had no idea about
the callbacks though - I will check them. I found I had to call
freerdp_connect on my own for some reason, but this does seem to work
properly.
Can you provide any hints for accessing the screen's bitmap data? I
looked in freerdp/graphics.h but only see prototype structures in the
bitmap structure. The graphics structure itself does not contain
anything promising itself, either.
The callbacks in the rdpBitmap which is called Bitmap_Prototype are
all unset save for New by default. Attempting to set them appears to
do nothing. The code below is rather sparse. Waiting 10 seconds change
anything, I suspected perhaps a full frame had not appeared.
I am passing only a username and host IP using the xfreerdp command
line syntax. Is it reasonable to expect to see the login screen?
Cheers,
R0b0t1
