HDMI to USB Capture Card Roundup
I'm looking for a cheap USB3 HDMI capture card.
These aren't capture "cards" in the traditional sense, but that's the way I still think about them.
My last captures were done using a Brooktree / Conexant PCI bus card on an ancient Linux desktop, so the silicon miniaturization and cost reduction available for the price of a burger at Five Guys is still a bit mind blowing.
But that card at least blasted full uncompressed data into my system, doing a nice job when I wanted to capture as much lossless detail off of an analog medium as I could.
That said, the USB Video Class capture devices are a really mixed bag, and it's really hard to know which ones are worth anything at all, even if they are cheap as chips.
So in the spirit of my last big blog post on dodgy Chinese hardware (see: USB serial adapter shootout), here's a post about the various USB capture cards I could find on eBay.
I'll try to give these devices nicknames, and as I figure out what chips they actually run, I'll post that here too.
To help people cross-reference these devices with eBay, I'll copy in all of the marketing pictures I can find there to this blog post.
It's really not easy to find brand names on these devices, nobody from Shenzhen will stand behind them, and I am too cheap to get a Magewell or Startech device.
Dongle 0: The One I Already Have
This thing is a pile of garbage and has really poor capture quality.
Here's what is captured with ffmpeg:

This is not great quality.
Clearly the coding chip in the dongle captures at a lower resolution or a high compression and everything fuzzes out.
I'd like to find a USB capture card that works better than this, ideally 1080p60.

This might be the updated version of the dongle I have, with USB3 and 1080p60, but I'm not spending money to find out.
Dongle 1: Rounded Metal, No Tail, USB A Plug
"4K Video Capture Card HDMI USB 1080P Live Video Streaming Game Recorder USB-C"
Dongle 0, the one I have similar to this, is also a USB 2.0 device, with 1080p30 resolution in MJPEG mode, and it looks really bad.
It's not even worth the 10 EUR they want for it.
Features:
* Unterstützte Eingangsauflösung: max.3840×2160@30Hz;
* Unterstützte Aufnahmeauflösung: max.1920×1080@30Hz im MJPEG-Format;
* Unterstützt 8/10/12 Bit tiefe Farbe;
* Unterstütztes Audioformat: L-PCM
* Unterstützt AWG26 HDMI-kompatibles Standardkabel: Eingang bis zu 15 Meter (1080P und weniger Auflösung);
* Unterstützt die meisten Erfassungssoftware wie VLC,OBS,Vmix, Potplay, Amcap usw.;
* Unterstützt Windows und MacOS;
* Entspricht dem USB-Video- und UVC-Standard;
* Entspricht dem USB-Audio-UAC-Standard;
* Ohne externe Stromversorgung, kompakt und tragbar.
* Abmessungen (L x B x H): ca.64x28x13 (mm)

Somehow I don't think this will ever be qualified for telemedicine. Maybe in China?
In another listing, the pictures are similar but a little different.
For example, the screws are different.
And they've added a little USB-C to USB-A adapter cable, and rotated some of the images.
I must be tired of life, so I order one.
I don't know who's doing their media packs, but they're doing a great job! 😀
I like that it's sitting on a faux mirrored surface, but the top and bottom images are not inverted?
