This may be a stupid question but I updated my Tumbleweed install today to grab the new Plasma 6.1 packages. I then eagerly installed krdp for remote desktop functionality. When I go to KDE System Settings, and then select the “Remote Desktop” sub-menu, I see the following error at the top of the window:
“Remote desktop cannot be enabled because your system does not support H264 video encoding. Please contact your distribution regarding how to enable it.”
I’m still getting the error. I’m not finding this error online, so I’m wondering maybe if I’m just need to install the right package or something. It’s a standard x86_64 Intel based Dell PC – an Optiplex 7070 to be specific.
Ideas are appreciated as I’d really like to take advantage of the remote desktop feature – I’ve been waiting for this functionality for a long time!
Looking at KRdp source, it checks whether h264 encoder is offered by PipeWire. Which shifts the question to - how to check and test whether PipeWire supports h264 encoding and what is needed for the support. Any PipeWire experts here?
My gut feeling is that openSUSE patches ffmpeg to load openh264 library on demand and checks that KRdp performs do not trigger loading of it. Internet search only finds this issue on openSUSE which indirectly confirms it.
In this case the most simple solution would be ffmpeg switch to Packman.
Whoever has this problem - do you have ffmpeg from openSUSE or Packman?
… quickly checking - yes, replacing ffmpeg packages (and only ffmpeg packages) with Packman version fixes KRdp error.
This needs bug report. If KRdp is not functional without Packman, it must be provided by Packman. If it works with openh264, it has to be fixed to work with stock openSUSE packages.
