I don’t know where else to post this because there’s not a HyperHDR or Hyperion subreddit. I posted this on /r/smarthome as well.
My HyperHDR components:
- Raspberry Pi 3b+ running HyperHDR OS (SD-card-image-64bits-aarch64.img.xz) found on its GitHub
- ESP-WROOM-32 ESP32 running WLED
- SK6812 LED strip
- SN74AHCT125N level shifter
- Ezcoo 4K HDMI splitter
- BIFALE 4K HDMI USB Video Capture Card
- 5v 15A power supply
- Dennon AVR-X1300W receiver
- Amazon Firestick 4K
The SK6812 led strips work and light up no problem at all, everything shares a common ground.
My janky ESP32 running WLED. Yes I know my picture has 3.3v going to the high voltage pin. I’ve corrected this in my setup.
Video Path:
- Firestick 4K -> Denon X1300W receiver -> Ezcoo 4K HDMI splitter -> HDMI Out 1 goes to TV -> HDMI Out 2 goes to HDMI capture card (with scaler switch set to 1080p) -> Raspberry Pi 3b+ with HyperHDR -> ESP32 running WLED
The Firestick resolution is set to 4k, color depth is 12bit, and Adaptive HDR.
HyperHDR connects to WLED via Wi-Fi because I don’t know how to direct connect the Pi and ESP32 via SPI.
Problem:
- when I play SDR content with HDR to SDR disabled, HyperHDR sees the video from the USB capture card no problem. The LED visualization is HyperHDR is bright, SK6812 LEDs are vibrant https://i.imgur.com/IXWN4TJ.jpg
- when I play HDR content with HDR to SDR disabled, HyperHDR sees very dim video, LEDs very dim https://i.imgur.com/ADPQzaR.jpg
- when I play SDR content with HDR to SDR enabled, HyperHDR sees no video , LED visualization is black screen, LEDs not on https://i.imgur.com/Z9o9Hpk.jpg
- when I play HDR content with HDR to SDR enabled, HyperHDR sees no video, LED visualization is black screen, LEDs not on https://i.imgur.com/djsXTOJ.jpg
I don’t have any idea what to do. I’ve tried switching HDMI cables, plugging the capture card to different USB ports, changing video capture resolutions and FPS, changing Firestick resolutions and HDMI always on/off, flipping scales switch on the HDMI splitter, bypassing the HDMI splitter and using Hyperion Screen Grabber app to send to HyperHDR running on the Raspberry Pi and also the Home Assistant HACS HyperHDR addon (still get black screen when enabling HDR to SDR). I’m out of ideas.
I suspect the problem is with either the HDMI splitter or the USB Video Capture Card. idk
