Resolume out without psychical second display #348

Open zbynekdrlik opened 1 year ago

zbynekdrlik commented 1 year ago

Hi, we like to move high quality 4k video between two resolume arenas over network. It is possible over ndi but quality and stability is not in required state. We don't like to have second 4k monitor to have possibility grab this screen over ultragrid sender. Have you any additional idea how to do it without that second screen?

Hi Zbynek, Resolume arena should support Syphon on Mac or Spout on Windows, right? If it is the case then you use Syphon -t syphon or Spout -t spout capture. See also -t syphon help or -t spout help.

Always crashing when using spout on -t.

Thanks a lot for reporting, I can reproduce the issue - #352. It seems to be linked to some upstream changes in Spout, because it occurs in 1.8.5 but not in 1.8.4 builds whereas there have not been any relevant changes in UltraGrid between those bug-fix releases.

I've already enqueued a hot-fix – it is already built in our continuous builds, feel free to try. It is not yet the final fix, I'd need to check what is going on, but it should be fully functional because the problem is only in setting Spout logging level, which is temporarily disabled.

Continues build now working correctly
