Elgato CamLink 4K DirectShow Pixel Format

@Muny Thanks reached out FlashCap!

Hmm, I just tried it in my environment (Ubuntu 22.04 x64 and ), and it is treated as YUYV (In RawPixelFormat).

I don't understand why only NV12 is listed. In fact, NV12 is a widely available format and I would like to support it in FlashCap, but it is not supported in the current version.

Maybe it's because I only tested with FHD in my environment. In your report, it is 4K resolution, and if it is 4K resolution, it may only be able to select NV12.

Thanks for the quick feedback. It seems you're right about the resolution the device is outputting having an effect on the reported formats from the Cam Link.

I changed my device to output 1080p video, and I now have a 4:2:2 YUYV characteristic (along with the unsupported NV12):

Cam Link 4K: Cam Link 4K (DirectShow), Characteristics=2
1920x1080 [YUYV, 59.940fps], RawPixelFormat: 32595559-0000-0010-8000-00aa00389b71 (YUYV 4:2:2 Packed 16pp 8bpc)
1920x1080 [Unknown, 59.940fps], RawPixelFormat: 3231564e-0000-0010-8000-00aa00389b71 (NV12 4:2:0 Planar 12bpp 8bpc)
