ezcoo SP12HVC with Raspberry Pi 4 - No picture

Lyr3x · 12. Juli 2021

I've tried the fairly new , which would reduce my setup from converter and grabber into one device (with better image quality). However, I cannot get it working with my Raspberry Pi(s). On a windows machine and a mac, it is working as intended. The Rpi does detect the capture card, and it shows up in hyperion as FHD capture card. But I cannot get an image out of it. I tried the capture card both on a Rpi3 and 4. Both running 2.0 Alpha9

v4l2-ctl show the correct resolutions and frame rates etc.:

Of course, i tried to set the device manually and reduce resolution to e.g. 1280x720 etc. No success. Maybe I overlook something?

Would appreciate any tips

EDIT: Its only partly working. I only see a video if it is HDR content. As soon as my ATV switches to SDR I have a black screen.

YUYV 4:2:2 is working fine, but SDR content is not. The grabber itself should work with YUYV 4:2:2 and RGB 4:4:4

Code

v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
    Type: Video Capture

    [0]: 'YUYV' (YUYV 4:2:2)

Thank you very much. Ambilight working again! Awesome. Couldn't find that before. Hope it runs stable now.

Interesting is that some values for contrast, saturation, hue etc. are killing the video. Like a saturation of 145 results ins no video at all. <145 and >145 is working fine again.

I ordered a mirabox to compare if I face the same issues. But the mirabox is plug and play and much better then my old cheap micro silicon grabber. I close that one here. I think the ezcoo is just not compatible with the pi.
