Best video quality, best internal splitter & fastest (they claim 50ms): Ezcap 320. Cons: Poor design/quality control, problems with a firmwares, mine won't work in USB3.0 but in USB2.0 with Rpi4. So it's a choice between $10 and $100 in my opinion. Didn't find anything interesting between. |

Got it. One last question ... what's the full-chain latency like on the
MS2109 and Raspberry Pi 4?
I'm watching some Hyperion videos on YouTube and it looks like a full
second or so of latency instead of instant reaction?

First models supported MJPEG (1080p30) and YUV (although at lower
framerate and resolution). They uses USB2.0. Then they started to
experimenting and there are clones of that clones using 'USB3.0': they are
rated for 1080p60 but only MJPEG..maybe something has changed. You must
check specification of particular model.

I was planning to use an ESP32 instead of ESP8266 unless there is a reason
to stick with the ESP8266?
Thanks so much for your articles. It looks like you recommend the APA102
LEDs but that the non-counterfeit versions are difficult to find. What you
instead suggest SK6812 RGBW (from BTF-Lighting perhaps?)

Frame processing for 360p is <= 6ms. The only way to break things is to
screw up 'smoothing settings' or to choose some very slow LED driver like
Adalight (115200 or even 500 000bps)..or to connect to the LED driver over
poor quality Wifi. Don't know what is your plan but if the LED strip is not
SPI driven like APA102 then consider seriously cheap ESP8266 wemos D1 mini
with CH340G or CP2104 or ESP32 also with CH340G or CP2104 as LED driver
(just make sure that the seller can provide it in that specification
because there are a lot of counterfeited items on the market).

Completely without surprise... I've done research last year: here are the
results
https://hyperhdr.blogspot.com/2020/11/hyperhdr-prepare-for-building-buying_14.html
. Don't know what is the current situation because they hide statistics
from the user quite well. The main goal behind HyperHDR is to provide low
latency system. In fact with disabled smoothing using Ezcap 320 and Rpi4 I
have reaction from the LED strip dozen milliseconds before TV starts
changing the image (some of that success comes probably due to fact that
Ezcap is receiving the image first and TV also has some latency in the
'movie' mode).

Oh, OK ... I see what you're saying. I thought the CH340G / CP2104 were on
the LED strip for some reason. It looks like I have a bit of reading to do.
Also, I thought an ESP32/ESP8266 were required but I think I'm wrong? I'm
going to be using a Raspberry Pi 4 directly connected to the SK6812 LEDs
(if possible, which I think so?). I was just confused because of your web
page recommendation of APA102.
I've been trying to research and it looks like the SK6812 also uses SPI so
it should be equally as fast?

I have many LED strips from BTF-Lighting . I was happy with them till the
last purchase: sk6812 RGBW cold white started to fail after few days (one
led after another, different segments). Probably bad luck. Next I purchased
92led/meter sk6812 but from other supplier. Personally I found RGBW cold
much better than neutral. Cold white is perfectly balanced, neutral white
is a bit yellow. Depends on your taste ...

Can anybody recommend a capture device for the Raspberry Pi?
I don't think I need 4K HDR but it would be nice for something that supports this to future proof my setup.
My main concern is lag/latency so I'd like something as fast as possible (?)
