Directshow (WDM) VideoDeviceIn limited to 1080p?

Hi,

Can anyone confirm if the implementation of DirectShow WDM for VideoDeviceIn in Touch is limted to 1080p?

I have a working 4k capture card that but can only pull in 1080p into Touch but not 4k. Tried
bypassing any possible driver issues by going through software with the Xsplit software pulling in 4k directly from card (OK) and then VideoDeivceIN using Xsplit (not card) + WDM and the same thing happens… only pulls in at 1080p.

Seems like touch doesnt support 4k in with DirectShow??
Anyone have USB capture cards working in 4k with Touch? If so which model?

Thanks.

Have you tried media foundation instead? That is the newer API

Yeah… same thing there only 1080p.

Hmm, it may be the driver then. Blackmagic is a good choice for 4K capture at a reasonable price point.
