HurryUpPinball - thank you for posting this. I followed the Buffalo Pinball article a few weeks ago to set this up for myself and it's nice to see it taken to a step-by-step video format.
I'm having some capture card compatibility issues - thought I'd document them in this thread since it seems relevant. I have the AliExpress LVDS to HDMI converter board installed in my Stern Black Knight Sword of Rage and jumpered correctly. Here are my results so far:
I had these two capture cards in my AV collection already:
**Elgato CamLink 4K (https://www.amazon.com/gp/product/B07K3FN5MR)**
Thought I had a winner right out of the gate. Got the video feed into OBS straight away, and it looked great. During my test recording, I noticed, however, that the video would blank out for 1 to 2 seconds every once in a while (in a couple of 10 minute test videos, each one had a dozen or so instances of the 1 to 2 second blank out). This is only on the video feed to the PC - no blanking at all on the pinball panel. I played with OBS buffering settings and different resolutions, no improvement. Tried a few different HDMI cables, no improvement. On to the next card.
**SunWSTD (https://www.newegg.com/p/30U-00ES-00001?Item=9SIAN03B7U8525)**
This one has no signal at all. None. Blank screen in OBS. Switched out the AliExpress HDMI connection for the one attached to the playfield Sony Handycam CX440 and boom, signal clear as day. I got this capture card on clearance a year or two ago for less than $20 - looks like it's relegated to playfield cam duty.
Now for the new ones....
**AVerMedia Game GC311 (https://www.amazon.com/gp/product/B07R6P2JJR)**
I bought this one over the weekend and it arrived today. The AVerMedia device listed in the Buffalo Pinball article is no longer available and this is the replacement according to Amazon. Like the SunWSTD....this one comes up blank in OBS with one added difference - the message "No Signal" is displayed from the AVerMedia device. Also like the SunWSTD - my playfield Sony Handycam CX440 works fine. Just for kicks, I tried using the AVerMedia recording and streaming software that was bundled with the device and I got the same results (eliminating any issues with OBS). I had a glimmer of hope when I noticed on AVerMedia's website that there was a FW update for the device - I updated it, but got the same results with AliExpress board. I'm boxing this back up to return to Amazon.
Here's hoping one of these will work - just ordered them this afternoon, should get here in a couple of days:
**LeadNovo 4K Capture (https://www.amazon.com/gp/product/B08Q86C71C)**
**Rybozen 4K CamLink (https://www.amazon.com/gp/product/B08DQWXV52)**
The Elgato 4K CamLink does "work" but my OCD can't deal with the screen blanking every once in a while. I'm really hoping this is indeed a compatibility issue that'll be resolved by finding the right capture card that'll work properly with it. I hate to think that I've got a defective LVDS to HDMI converter. It took 6 weeks to get here from Hong Kong!
