DM814x run xfreerdp with RemoteFX issue

Hi，

Anyone has experience on running xfreerdp with enabling RemoteFX dec on DM8148?

I already installed TC-RDK 1.0 RC3 from TI and setup rfx modules by following the userguide. But when I run xfreerdp command on device console like
"sudo xfreerdp -f --rfx --composition --fonts -u xxxx -p xxxxxx 192.168.1.105"
I got the failure result like below:
connected to 192.168.1.105:3389
creating directory /home/user/.freerdp/certs

The above X.509 certificate could not be verified, possibly because you do not have the CA certificate in your certificate store, or the certificate has expired. Please look at the documentation on how to create local certificate store for a private CA.
Do you trust the above certificate? (Y/N) y
failed to connect to socket: No such file or directory

If run xfreerdp without --rfx option, it works fine.

Anyone can give me an advice? How can I verify the remotefx already installed in my device correctly?

My device spec:
DM8148 1GHz + 1GB DDR3 + Ubuntu OS(TC_RDK 1.0 RC3)

Thanks a lot!
