On a client notebook with integrated Intel UHD-Grafik 605 running Windows 10 a video player complains that "it seems there is no Xvideo support for your video card available".
And, indeed, xvinfo reports on the client:
$ xvinfo X-Video Extension version 2.2 screen #0 no adaptors present
So, is it VcXsrv which lacks the support or any of the X libraries? Is there anything that can be done about it, like loading a module or such?
No, it is x2goagent. It implements the xvideo extension. But Wikipedia states:
"In order for this to work, three things have to come together:
- The video controller has to provide the required functions.
- The device driver software for the video controller and the X display server program have to implement the XVideo interface.
- The video playback software has to make use of this interface.
And I guess there's no "device driver software" that could take care of the rendering. Which is kind of logical, as there's no hardware within x2goagent.
I have not researched what is needed to make that work inside X2go (or precisely: NX). but I also think it is not really worth the effort as video is discouraged anyway because of performance issues.
Now, to help you: you might be able to instruct the video player to ignore the extension. Another possibiliy is to switch it off in x2goagent. You can achieve this by editing /etc/x2go/x2goagent.options on the server side and change the line X2GO_NXAGENT_DEFAULT_OPTIONS="" to X2GO_NXAGENT_DEFAULT_OPTIONS="-extension XVideo"
Then start a new session.
