Hello, I have a C++ app that outputs a framebuffer and want to expose that over RDP. I want to use Apache Guacamole as a client and have started using code from this sample: https://github.com/FreeRDP/FreeRDP/blob/master/server/Sample/sfreerdp.c
The Windows RDP client (mstsc.exe) works fine with it since it supports RemoteFX, but with Guacamole it does not, as it doesn't support RemoteFX or NSCodec ( https://github.com/FreeRDP/FreeRDP/blob/master/server/Sample/sfreerdp.c#L183 ). I assumed that guacamole expects data to be raw/uncompressed (?) so I modified that code to instead do: const size_t len = rect.width * rect.height * 4; if (!Stream_EnsureRemainingCapacity(s, len)) return FALSE; Stream_Write(s, myframebuffer.data(), len); cmd.bmp.codecID = 0; Instead of rfx_compose_message or nsc_compose_message. But, I see a black screen on Guacamole. I have set up guacd and can confirm the connection goes through (and I can move the mouse on the browser), but the screen is black, no matter what data I send. Am I sending it right above? I assume I sort of am, since if I use freerdp as a client with: freerdp /bpp:32 /cert-ignore /v:localhost /log-level:TRACE +gfx-thin-client I can connect just fine, though the screen is inverted and colors are wrong (alpha channel is probably inverted with alpha). So side question, how can I specify the format with FreeRDP's APIs when using no encoder like I am? With ie. RFX you just specify them in rfx_context_set_pixel_format. guacd log: https://pastebin.com/raw/Fi28hidq FreeRDP log: https://pastebin.com/raw/gKzLSCMT guacamole.properties: "guacd-port: 4823" (the default of 4822 did not work for some reason) user-mapping.xml: <user-mapping> <!-- Per-user authentication and config information --> <authorize username="admin" password=""> <protocol>rdp</protocol> <param name="hostname">localhost</param> <param name="port">3389</param> <param name="security">rdp</param> <param name="ignore-cert">true</param> <param name="disable-auth">true</param> </authorize> </user-mapping> Tomcat log: (nothing of note) I would appreciate any help, I can provide additional information if need be.
