Remote Desktop Low Framerate - Missing OpenH264 ?

Hello, my work provides a portal that lets you download a .rdp file, which has all of the connection settings and a cert baked in. They have enabled a high bandwidth connection so that it basically feels like real time, i.e. same hz as my local PC, and graphics/audio so you can even watch things youtube videos and it be reasonable okay. I've been trying to use this on Bazzite and have only been able to get it to work in FreeRDP (via terminal) and Remmina (via Flatpak). There are a few other options in Flathub that I tried, but they all seem to just outright fail, I assume because they haven't been setup to use rdp certs. - Remmina :: I will probably uninstall because it's quite unstable, whenever I try to get it to expand across all 3 monitors it just crashes. However, it does have nice framerate when running on a single monitor - FreeRDP :: This is nice and super simple, expands naturally across all monitors, however it's got quite a bit of latency and feels like ~30 fps. It's usable but hopefully can make it better. Looking at the logs, it seems like FreeRDP is missing OpenH264 codec. (Removed a bunch of the log so it fits in the post, as well as redacting my domain stuff)

However it is in the Flatpak software as part of install (I assume since I didn't install it) flatpak list | grep 264 >

Riv@Serenity:~$ flatpak list | grep 264
openh264    org.freedesktop.Platform.openh264    2.1.0    2.2.0    system
openh264    org.freedesktop.Platform.openh264    2.4.1    2.4.1    system
openh264    org.freedesktop.Platform.openh264    2.5.1    2.5.1    system

Riv@Serenity:~$ flatpak list | grep 264
openh264    org.freedesktop.Platform.openh264    2.1.0    2.2.0    system
openh264    org.freedesktop.Platform.openh264    2.4.1    2.4.1    system
openh264    org.freedesktop.Platform.openh264    2.5.1    2.5.1    system

FreeRDP must be part of the base Bazzite image which xfreerdp

/usr/bin/xfreerdp

/usr/bin/xfreerdp

rpm -qf /usr/bin/xfreerdp

freerdp-3.12.0-1.fc41.x86_64

freerdp-3.12.0-1.fc41.x86_64

And I assume this means that FreeRDP isn't able to access the flatpak version of OpenH264. Do we solve this by just doing an rpm layered package of OpenH264? Would that potentially cause conflicts with the flatpak version? Has anyone tried any other options from connecting with .rdp and having a smooth experience? Thanks!
