Unsupported format MFVideoFormat_P010 for Elgato HD60S+

Unsupported format MFVideoFormat_P010 for Elgato HD60S+

Hi,

Just got my capture card, Elgato HD60S+.

Although it supports UVC, Linux still doesn't support it (yet?)

[34381.339277] uvcvideo: Unknown video format
30313050-0000-0010-8000-00aa00389b71

After a little search, that GUID looks like MFVideoFormat_P010, which
looks like a 10bit YUV format, and ffmpeg looks supporting it.

Any idea on the Linux support of that card?

Thanks,
Qu

It looks like there are still supported format, but guvcview can't
detect the device.

But OBS can utilize the device.

So it's a user-space problem...

This format is mapped in DRM already, you will need to map it into the
V4L2 enum, document it and then add the mapping in the UVC driver.
Should not be too hard.

https://docs.microsoft.com/en-us/windows/win32/medfound/10-bit-and-16-bit-yuv-video-formats

You could also add P012 and P016 while at it. These are not super
memory efficient in 10 and 12 bits, but they are compatible with 16
bits and are efficient to read/write.
