My device (Xperia X5 Premium) supports the hardware encoding of 4k videos (3840 x 2160) with H264 or HEVC (265), which I would like to stream via WLAN to the software on my PC. Unfortunately, after testing multiple IP camera apps, none of them can access the 4k feed. All report 1080p as the best available quality.
I'm wondering if this is a limitation of the API (although the open source app "Open Camera" is able to access my camera in 4k modes) or just an arbitrary limitation imposed by the various developers was programmed firmly. Does anyone know of an existing IP camera app that supports 4k cameras?
