how to check if 264/avc 444 mode is used in windows 10

dfk1976
i've compiled apache guacamole version 1.2.0 and have setup a test rdp
connection to a windows 10 machine. under the gpedit.exe i activated the
h.264/avc 444-graphicmode on the windows 10 machine and rebooted. than i
connected over the rdp protocol and expected in the event logs an entry in
-> applications und services logs -> microsoft -> windows ->
remotedesktopservices-rdpcorets -> event id 162 but there was not such an
entry. so how can you check if 264/avc 444 mode is used in windows 10? does
apache guacamole support /gfx:avc444 at all?

As far as I know, no, Guacamole does not have any matching support for utilizing the /gfx flag or any values there.

so the next question is, what happens in the backgroud of apache guacamole
when connecting over rdp. normally the command line parameter /gfx:avc444
exists in xfreerdp − FreeRDP X11 client. and perhaps it is possible to
implement this parameter somewhere in the code, perhaps also to have a new
option in the webfrontend of apache guacamole. so if there is someone of the
developpers who knows more about it please tell if it is possible to
implement /gfx:avc444 or not.

Guacamole leverages the FreeRDP API, so it is, under the hood, using the exact same libraries and calls to make the RDP connections as the xfreerdp client would use.  That said, it's doing so in quite a different way - translating that from RDP to Guacamole (the protocol) rather than interfacing with X11, for example - so there are some differences.

This could likely be implemented, just takes someone to do the work.  Also, I'm not sure if it's related, but there's a JIRA issue out there regarding RemoteFX support:

This post was updated on .
so if it's doable to implement 264/avc 444 mode than apache guacamole would
profit as the avc codecs are the most modern and promises the lowest CPU
utilization on the client with a low network load and the best image
quality. if someone can do it for the next guacamole release this were a
sensible extension. unfortunately I am not able to program this myself.

You are welcome to put in a JIRA issue to request that this feature be implemented.  The timeline for implementation will be determined by 1) the ability and/or willingness of someone to do the work, and 2) the overall importance of the issue to the entire community, usually determined by the number of votes on the issue.
