Media server plugin on a XD1034, 4k no picture with vlc

I trying to configure the media server plugin to make the display stream avaialble to VLC.

This works for a 1080p presentation with a 1080p content, a 2160p presentation with 1080p content, but not for a 2160p presentation with 2160p content. VLC conects, but the content is just a black screen. The content is displaying properly on the 4k screen to which it's connected.

I see the following errors in the log:
[   29.727] MediaStreamer::SetPipeline called with display:mode=1&vformat=1080p30&vbitrate=8000,encoder:,mem:/display

Here is some additional information

  • media server pluging: https://github.com/brightsign/BrightAuthor-Plugins/tree/master/Media-Server
  • Output command: pipleline$ ="display:mode=1&vformat=1080p30&vbitrate=8000,encoder:,"    (This will automatically default to mode 2, as 1 is not suported)
  • Device: XD1034, Firmware: 8.4.10, Autorun version: 7.9.14
  • Presentation: screen resolution: 3840x2160x30p
  • Picture: 3840x2160, 72dpi, 24bpp, png

Any idea what I could be doing wrong?

    The player's encoder can only handle up to 1080p.  So you can't encode a display output or input larger than 1080p.  That's why it works for 1080p output but not 2160p output.  For larger resolution you'd need to use a dedicated encoder.

    Thanks for the information. I will then use a different method for the 4k content.
