Is there a USB HDMI capture device that handles 50fps?

[AVR2]

I want to be able to capture native 1080p50 over HDMI, but the cheap MS2109-based capture device I bought only supports 60fps (as well as suffering the mono audio problem). Are there any USB HDMI capture solutions that definitely handle native 1080p50? If they correctly pass a stereo audio output too, that would be even better.

This problem comes with most of "these" consumer devices, you need to tell what your HDMI source is, is it a consumer (media copyrighted material) "livingroom device" or is it a video camera ?
That's a big difference…. do you need a "live" stream, or just a "recording" ? you don't need to capture HDMI, because it's already digital…i would go for a HDMI recorder or a good HDMI PCI card, and if needed… HDMI passthrough to get rid of HDCP, (when needed) this way the hardware provide you with all the correct video settings, or being able to set these in the correct way. A HDMI USB dongle is not a good option, these are mostly misses than hits...

btw, do you already use a video-switcher in your workflow ? you give not much information about your setup/workflow….

The bit more expensive but still cheap similar looking devices that use the MS2130 chip should be able to and they correctly capture stereo sound. The quality, of course, will not be great since they are cheap. I did notice that with mine that a short or no extension cable needs to be used otherwise the device will use USB2 rather than USB3 transfer mode. If the device goes into USB2 transfer mode than it only capture similar to a MS2109 device. I've got mine to capture with OBS and ffmpeg (using -f dshow).

I previously posted a sample of a capture from my MS2130 device and the original source material if you want to see what to expect from the MS2130 devices. The link for the post is https://forum.videohelp.com/threads/409268-Cheap-HDMI-Capture-Device-is-it-worth-it#post2687036

ffmpeg reports the following capture modes when it is working in USB3 mode:

It looks like the Startech USB3HDCAP does. I don't have any 50fps inputs available but HD 50 is certainly in the list of possibles:

Beware though that it is very strict on HDCP; it will not let anything through from a Panasonic VHS/DVD/HDD machine, including home made movies. That can be defeated by a splitter.
