REAPER as media server
Hi everyone!
REAPER is insanely good at playing back videos, and it works remarkably well playing videos while synced to an incoming timecode (MIDI MTC or SMPTE LTC). The best thing is the overall snapiness, reliability and the fact that it doesn't care which framerate or codec, as long as it's playable by VLC. It just works. So I've been using REAPER as a video media playback server on several occasions successfully but the thing that's missing is multi simultaneous video layer outputs. Separate video outputs for lower-thirds (in a broadcast/stream situation), different content for several LED video walls (in a live situation) etc. Several REAPER instances in video fullscreen mode works as a workaround. You can screengrab several REAPER instances in OBS, transform it to several separate NDI streams or 1 Spout stream, send it over the network to whichever receiver (maybe Resolume Arena which does its FX and LED wall pixel mapping magic). However, you can't screengrab several REAPER instances on the same machine in video fullscreen mode - the video windows will appear correctly to be grabbable, but they will all show the same video. You'll have to dock the video window in the main window (which automatically resizes it to less than native resolution). So, is anyone else using REAPER as media server? What are your tricks? What would be the simplest solution to expand that functionality? Native NDI support? (There's already a feature request here: https://forum.cockos.com/showthread.php?t=247191)

To whom it may concern:
REAPER 6.45 now supports OpenGL video output This makes the REAPER fullscreen video window OBS-window-grab-able OBS can turn any grabbed window to an NDI stream So if you're running several REAPER instances you can output several timecode-synced video signals as NDI or Spout via OBS. One step closer to REAPER as media server - this is great!

as somewhat of a workaround for me, is to grab the video window using ffplay and then my other apps can then 'see' the video window to grab it
ffplay -f gdigrab -framerate 30 -i title="Video Window" -x 1280 -y 720 This is one way to screen grab the video window (even if not fullscreen). Then, in another app, I can grab that window Logitech Capture will also grab app windows and then if you have an app that can access a video device, the logitech directshow cam will appear and show what app window you grabbed. hope this give some options why can't someone just code up a spout sender for the video window? |
