Elgato HDX 120 modes

[d4rkdpg]

Hi I recently replaced my MS2109 with elgato hd60x. Im trying to list supported formats for this device like the hyper hdr blog review for this device but cannot see 1080p 120fps. Tried on ubuntu (dell laptop) and raspberrypi os (raspberry pi 4) I'm running this:

v4l2-ctl --list-formats-ext -d 2
ioctl: VIDIOC_ENUM_FMT

The firmware is up to date as of yesterday. How can I achieve this?

Thanks

Hi
It works for me under the Windows 10 because I use that system to test the grabber's latency. Linux drivers are behind this grabber capability.

[d4rkdpg]

I see ok thanks any unofficial drivers or workarounds ?

[awawa-dev]

I haven't found any. It's not the first such situation with USB grabbers under Linux e.g. popular MS2109 doesn't support NV12 codec which Windows driver supports.

[d4rkdpg]

Just to add I tested this on windows and can get 120 in 4 k capture utility but with hyper hdr still shows up max 60 fps, 120 not shown any ideas?

[awawa-dev]

Did you connect to USB3.0 and use 1080p signal on the input?

[d4rkdpg]

Yes i did

[awawa-dev]

1920x1080x120 is only supported with NV12 codec.

[d4rkdpg]

Yes I know and on my Windows installation of hyper hdr I cannot see 120 fps in video capture section under 1080p NV12. But under elgato utitlty under capture 120 input no problem. I’m I missing something here ?

Verify your HyperHDR logs. Video modes are listed there.
