Blackmagic Outputs #124
Comments
|
It would definitely be a handy feature. But maybe a bit time consuming to add, and I don't have any device to test it with. But I'll see what I can figure out. 😊 |
|
I saw this project on github: https://github.com/Streampunk/macadam which uses node.js and the Blackmagic API and has a handful of other repositories that it's used in. I'm not proficient in Electron, or I'd give it a shot myself. I have some spare decklink PCI cards which if you're interested, I may be able to send you one to play with if you think this is something you'd be interested digging into. I realize though I'm sure you have a ton of other priorities for this project. |
|
Thank you! Yes, I have some other priorities first. But I'll let you know if I need it, and have the time to do it. The package looks promising. |

Big +1 to add true SDI output. |

Big +1 to add true SDI output. I was looking for years to a alternative to PP7... i found hope. I pray for you guys for shure. Thanks for our effort. When you @vassbo (and others) ever will come to Switzerland, let me know. I created a git profile to write this. |

Thank you. @marcorychlik 😊 |

+1 for me aswell. Would be the incentive for me to switch. Key + Fill is essential in my application. |
|
+1 |
|
+1, this is literally the only thing holding me back from switching. I've got a number of systems with various Decklink devices, including 8K Pros and Duo 2s, and we composite using ATEM so simply switching to NDI isn't really an option for us. |
|
Created an account just to say this feature is holding me back from being able to switch as well. Now that ProPresenter have announced a subscription-only model, hopefully this brings in donors who are switching away from Pro7 and fund the features we need to be able to switch and donate too. |
|
I was the one that originally requested this feature. I've found the best way of getting around this is to use a regular graphics card and then HDMI to SDI converters. It's basically what a deck link is already doing (minus the input abilities). It's actually easier to set up and troubleshoot going this route. What I do wish was possible would be to lock the mouse or other content from being accidentally moved to one of these screens since windows now has direct access. |
I think the main thing decklinks would give is key+fill. Atleast I and I think alot more are using ATEMs or similar to put text on top of other content. That would have to be done with a greenscreen. But that feels like a step in the wrong direction for me. For playouts where Freeshow would display on the entire screen your suggestion is sufficient. |
Exactly, we have a Decklink Duo 2, and we use key+fill. We have an ATEM Television Studio HD that we put it all together with. |
|
If you have a Blackmagic device (e.g. DeckLink), and some coding knowledge, please help with testing! :) I have added basic support for Blackmagic outputs/inputs on this GitHub branch (with the macadam package): https://github.com/ChurchApps/FreeShow/tree/blackmagic All the basic functionality should be there, like sending out video data (in Outputs settings) & receiving video streams (in "Media">"Screens">"Blackmagic"). But I do not own any Blackmagic device so I can't test it, I have no idea if it works at all! Here's a test build (Windows): https://filetransfer.io/data-package/T9GcC2xT |
|
+1 from me. This is basically The Thing I would need, and that's it. |
|
@vassbo Do you have a PO Box one of us could send one to? They're $145 for all you would need to test it |
|
@brettgoodrich Thanks, I have a friend currently testing it, do you also get a green output screen? If I can't figure out that issue I might have to buy a DeckLink, but that could come in handy elsewhere. Do you think I just need a DeckLink, or would I need some other hardware as well? Edit: I only have a laptop, and I guess I would need PCI input for DeckLink, have not found a good test solution that supports laptops. |
|
(I think FreeShow needs a Discord for the purpose of community of engagement, troubleshooting, and chat threads like this, but anyways...) A mini monitor or mini recorder would get you in the ballpark for testing, but for those above who were talking about key+fill, you'd need to get into the PCI DeckLink product line, starting with the DeckLink Duo 2 or DeckLink Quad or something like that (those are older versions), but will certainly allow you to test everything, especially as more features are requested if this SDI out is successful. I'm happy to chip in some money toward this if you need to purchase some additional hardware. |
|
The current (free) workaround that I've tested for outputs is running NDI output from FreeShow to OBS and using the stock Decklink option or DeckLink filter (https://github.com/cg2121/obs-decklink-output-filter) |
|
I tested this build with my 8K Pro pipeline. In our setup, we use ProPresenter on three outputs which all go to our ATEM. We normally run these at 1080p59.94 with no transparency (key/fill). Our 4th port is used as 2160p59.94 input from the ATEM's program feed, and that goes into OBS for our livestreaming. In this test I just slotted FreeShow into one of the ProPresenter output feeds. I had no visible input at all, until changing the Pixel Format after enabling the BMD output. Once changed, both 8-bit YUV and 10-bit YUV seem to 'work', in the sense that they output picture. What they output is obviously not what's intended, but it's also different depending on the setting. Also, the resolution setting doesn't seem to do anything. When changing resolution it does seem to 'refresh' the image (cycling black then back to video), but regardless of whatever I have it set to, it only outputs at 1080i50 according to the BMD Desktop Video Setup software. I've attached four images - the outputs of 8-bit and 10-bit YUV, as captured in OBS, when OBS and the ATEM are set to both 4K and 1080p. Hopefully this mostly 'raw' pixel dump might help you troubleshoot what's going on. 8bit_1080p For what it's worth, you do seem to be accurately obtaining the supported video modes for the specific Decklink card, as I see every resolution mode from 525i59.94 NTSC to 4K DCI 60p. |
This is exactly what I got too, though with 1080p50 and a mixture of one Quad card and one 8K card |
|
Thank you @Yttrium-tYcLief I'll see if I'm able to do something about this, and post a new test build. |
|
Hey, any word on a new test build? Happy to try it out whenever needed. |
|
@Yttrium-tYcLief Will let you know, had to prioritize some optimizations and bugfixes first. |
|
Any progress on using Black Magic to run Free Show? Our church is really in a pickle trying to figure this out. Thanks |
|
@Yttrium-tYcLief I might have figured something out! Here is a new test build for anyone interested. |
|
I tested the latest (FreeShow-1.2.9-beta.1-x64) with a Decklink Quad 2: ProPresenter works fine. I included the Decklink Status Report for the two outputs. ProPresenter always uses YUV 4:2:2 8 bit for non-alpha output and BGRA 8 bit for outputs with an alpha. The Freeshow beta seems to temporarily connect to the decklink once, but if you close and open it, it doesn't detect the Decklink at all. System restart does the same thing, it doesn't detect the Decklink. To re-detect the Decklink I had to remove Freeshow, remove the Freeshow MyDocuments folder, and also remove the folder from the hidden AppData folder. From the dropdown, Freeshow in 1080p60 only allows YUV 8 bit and 10 bit, no BGRA. I believe the connection issue to the Decklink card needs to be resolved, as it seems like Freeshow momentarily connects, then quickly loses the connection. This might also just be my experience with the Quad 2. I have a Duo 2 as well, but I lacked the time to test it. |
|
I have a mac and I have a decklink quad and Im proficient in programming. I've dabbled a little with electron. I'll try to give it a shot. |
|
@chalamministries Let me know if you make any progress on this. :) |
|
I couldn't get it to compile on my main Mac. I got to dig and find out what's going on there. But yeah I'm working on it. |
|
Awesome. Thank you!

I'm running into a lot of depricated dependencies. Im afraid to upgrade all of this as it would affect the main version. I can't get it to build properly. Am I missing something that you are doing to run it? |
|
All right, do you think this can fix the deprecated dependencies?: #1016 |
|
We ended up having to purchase new Propresenter bc the old one was no longer supported and Freeshow wouldn't run.

@LPChurchNeeds If you need Blackmagic integration at the moment your best bet is ProPresenter yes if you have the money, but it's expensive. I'm sure we will support devices like DeckLink very soon! |
|
Thanks. Yes. We got stuck, couldn't figure it out, seemed like Freestone would work, but it did not.

@vassbo Thank you for working on this. Will FreeShow eventually support fill/key output for BMD UltraStudio HD Mini or UltraStudio Mini 4K via USB-C output? We are considering buying this hardware for overlays using ATEM SDI Extreme and FreeShow, but the fill/key output is essential for this to work as we stream straight out of the ATEM and not use OBS for overlays. I know we can use overlays using NDI source and OBS, but we are trying to not to use OBS for our streams. |
|
@amudhanr We should have support for BMD key/fill once we get this actually working, not sure when exactly. |
|
Sorry, I haven't been keeping tabs on this but if there are any builds in the future, I'd be happy to test them. We now have two separate systems, one with an 8K Pro G1 and one with a Duo 2. |
|
If you want to try and compile the build that is in the repo, I got the outputs to work on the deck link duo but I have not tested anything else nor have I gotten inputs to work. I also don't have anything set yet for key and fill
|
|
Just letting everyone know, I'm still working on this enhancement. Feel free to build the blackmagic repo and try the outputs. I still have to work on the inputs. |
You probably already know this, but having the ability use Blackmagic products that can do SDI out would give you a huge bump in market share. Have you yet investigated what it would take to use an output like a Blackmagic decklink?
