Default Routing Video to video card

Hi,

At the moment it is only possible to get a video playing in a window on the screen.
It will be vEry vEry handy if this can become routeable to something like a Blackmagic Decklink SDI card. This will enhance the workflow in our studios massively. At the moment we circumvent the problem by adding a hdmi to sdi converter, but this occupies an extra port.

Any chance this is going to be implemented in Reaper??

Best, Jeroen

Is there some kind of standardization for such things? Drivers, specs anything, that is used in the industry, so the devs can have a look at that?

I second having output to a dedicated card.

I have a Blackmagic Intensity pro 4k which I'd imagine uses the same api calls to the driver as the Decklink cards.

I suggest the devs look at the libraries required to access video capture playback via the OS.
VLC linux can see the card and both capture and output to it. There's a beta for Windows. This guy
https://github.com/videolan/vlc/commits?author=robUx4
on github is working on it.

Since vlc is used by Reaper, can calls to the card be made by proxy or can the code be used to access Decklink/Intensity Pro directly in reaper list of video engine??

If REAPER could output video via Blackmagic's DeckLink, Intensity, Shuttle, or even UltraStudio devices it would free up the second video output on my graphics card and I could gain some screen real estate.

From what I can gather, Blackmagic uses a unified driver that uses common calls to their playback and capture devices. An SDK (currently Desktop Video 11.4 SDK) is available on their website. I guess it would need to be integrated into REAPER which might come with some licensing issues - I know Zeranoe had to drop DeckLink functionality (-f decklink) from their FFMPEG builds back in 2016 due to licensing issues.

Holding thumbs and not my breath!

I forgot +1 from me as well, as this would be very beneficial for those, who do scoring or audio-overdubbing on movie/video-projects.

Big +1 from me. Really miss being able to run dedicated video off my Decklink card. Made things so simple.

Coming to think of it, there is a decklink module available for gstreamer at https://coaxion.net/blog/2014/12/imp...ecklink-cards/

Now if it would be possible to sink the video out of the JS video processor into gstreamer, and then pipe it to the decklink card, it would help things getting on the road.

The article doesn't mention any license fees which gstreamer should cough up.

Maybe a path to follow?

Cheers, Jeroen

I wholeheartedly support this call - its a must for facilities dealing with vision playback.

One alternate that I am investigating is putting to use one of my old MacMini's as a dedicated Video Player slave. I have done this in the past with dedicated Apps, and its great as it free's up resources on the audio machines.

If this is programmable at all, then one programmatically gifted could have a look at these two files from Justin's dev-server:

https://landoleet.org/dev/video_frame.h
https://landoleet.org/dev/video_processor.h

They seem to allow access to the video-processor chain. Maybe rerouting it via an extension-plugin or a vst-effect could be done that way?

If Blackmagic cards support once happen in Reaper I would buy Reaper again or donate double(or even triple) price to developers No kidding!
Edited: I figured out how to play video in standalone VLC player itself thru blackmagic cards, but obviously Reaper just uses VLC engine its special way with its own settings. Maybe anyone knows how to change the way that Reaper deals with VLC player so that it would use VLC's settings?

Default Mac M1 Totally need this

On the mac Mini M1 we are limited to two monitors. The addition of a video stream would be a God Stent, if not a necessity for folks doing Post work.

PLEASE REAPER WE NEED THIS

Default Keeping this thread alive

Yes, the post folks are really interested in this. My facility is Reaper based, and our studios were outfitted with output cards by our installation vendor. This would be a huge get.

Still no sign of this happening in v7

Please add the ability to output video to a dedicated card such as Decklink, it is so much better, and runs a lot smoother.

Also missing this feature. Here's more obvious thread name to notice for developers
