vMix IO Beta is now available!Downloadhttps://cdn.vmix.com/download/vMixIO-Linux-x64.zipInformationvMix IO is a free application that converts capture devices into Open Media Transport (OMT) inputs and outputs on the network. More information on OMT can be found at https://www.openmediatransport.orgIt does not require a GPU, and is controlled via simple web interface, making it a cost effective companion to a main vMix PC where more inputs are needed. System Requirements* PC with an x86_64 processor supporting at least AVX2 (no GPU needed!) * Minimum 8GB of DDR5 memory. Dual Channel memory recommended for > 4x 1080p sources * Linux Mint 22.3 or higher (Other Debian based distributions higher than version 12 should also work) * A Blackmagic DeckLink capture card with the latest drivers installed. (Other capture cards that support V4L2 (Linux) should work but have not been tested) * A gigabit network card (2.5Gbps required for > 4x 1080p60) (Intel and Realtek 2.5Gbps network cards have been tested) More information and installation instructions can be found in the README inside the download. Reference system and case designHardware specs for a recommended system along with case designs to print a compact MiniITX case can be found below: https://github.com/vmixhd/vmixiocaseWhere is the Windows version?A Windows version of vMix IO is expected to be released later. However, as the goal of vMix IO is to be a (relatively) low cost network device, Linux is the focus of the initial release. Bug ReportsSimple bug reports can be posted in this thread, however for more complex discussions please create a separate topic within the Beta Discussion forum.

Thanks for spotting that. It is a typo it should be 22.3

Briefly tested vMix IO on a Debian 13 Trixie (virtual) machine. Needed to install the following additional packaghes: Code:sudo apt install libsamplerate0 webp avahi-daemon libavahi-client3 libasound2t64
And to get vMix IO up and running: Code:
sudo apt install unzip
sudo mkdir -p /opt/vmix-io && cd /opt/vmix-io
wget https://cdn.vmix.com/download/vMixIO-Linux-x64.zip
sudo unzip vMixIO-Linux-x64.zip
sudo chmod +x vMixIO
sudo ./vMixIO
I tested with a Decklink 8K and Decklink IP. For this the following steps are required: Code:
sudo apt install build-essential dkms linux-headers-$(uname -r)
tar -xvf Blackmagic_Desktop_Video_Linux_*.tar
cd Blackmagic_Desktop_Video_Linux_*/deb/x86_64/
sudo dpkg -i desktopvideo_*_amd64.deb
sudo apt install -f
After this I was able to start vMix IO, define some Inputs and take the OMT feeds in vMix. I was not able to test the Outputs because the Decklink cards require a UI/X-server and I'm running a headless (virtual) machine.

Testing with Linux Mint and SDI-connected camera via BMD Mini Monitor 4K (Didn't have a DUO2 or Quad2 on hand at the moment).
IO Input 1 shows up as 1080p29.97 regardless of the camera settings (1080p59.94, 1080p60).
Is this a feature or a bug or OE?

Hi,
When creating the input in the web interface, did you leave the format set to "Auto"?
If so, this will rely on the signal detection of the card itself, and on some older cards this may not be available.
If the input provides vMix IO with no signal detection, then you will need to manually specify the format when adding.
Regards,
Martin

So I tried 1080p59.94 and the input reverted to 1080p29.97 after a second or two. Tried some other resolutions/frame rates with the same result. I have a Duo2 arriving this weekend. I'll try it and report. -Tom

That would appear to indicate it is detecting that as the signal of the source.
Does it show a picture at all or does it only show blank? Can you verify what the signal format is in Media Express when vMix IO is not running?

About one frame per 5 second. Signal format in Media Express is 1080p29.97. Verified camera is set for 1080p59.94.

Ok that seems correct then.
vMix IO can't do any format conversions, so if Media Express shows 1080p2997 then that is the actual format of the source connected and what vMix IO will use.
Otherwise the picture would be blank.

UPDATE
Removed Decklink Mini Monitor 4K and installed Decklink Duo 2. Added a 2nd SDI camera (BirdDog P120 1080p59.94) as Input 3. First camera is PTZ Optics Move 4K 12X at 1080p29.97 as Input 4. (Inputs 1 & 2 were added as ports 1 & 2 but are black as no camera is selected.
(I love how the Add Input automatically advances to the next Device available. Very nice.)
Used Auto format and Quality set to High on both camera Inputs. In vMix, all four Inputs were added.
At Home screen, Input 3 shows an image and correct resolution/frame rate, but shows zero Connections.
In Statistics, Input 3 (P120) does not show up. Zeros across each category. Input 4 (PTZO) shows data in each category.
Deleted Input 3 in vMix and re-added. Now shows up as 2 Connections and also shows in Statistics.
All in all -- Pretty Slick!
Interesting side note: If I close Firefox in Linux, the vMix production still shows the active cameras. If I start FF again and navigate to the vMix IO URL, all four Inputs appear in FF as soon as I log in.

Possible Bug
Removed Input 3 (P120) at High Quality. Replaced it with same camera using Auto quality. Noticed that the default Input number was not 3, but 4. Still added it. Now I have two Input 4's, one for P120 and one for PTZO camera. The P120 Input 4 shows 0 Connections and is also not available in vMix as a OMT source.
If I remove that IO Input and re-add it, but edit the Input number from the default (4) to 3. Everything works properly.
