Hi, I bought a Ugreen 25173 and didn’t manage to get the LUT calibration done. I use a ezcoo SP12H21 splitter with scale down enabled. I tried different resolutions with p010 but the calibration fails. It ist always waiting for the box. I let the video run 1 time, or does it have to be in a loop? Do you have a little write up? Or, even better a LUT calibration file for the ugreen? :) Thanks in advance. |

Hi Start the video and then after few secs start the calibration. Just like in the tutorial. The video must be playing before starting the calibration.
this is something different and that message doesn't lie. Use p010 1080p25 and have 'Quarter of frame mode' disabled. |

I use a ezcoo SP12H21 splitter with scale down enabled. The IN comes from the receiver, out 1 to the tv. Out 2 goes in the ugreen, which is connected to the pi 5 via usb 3.0. I flipped the video horizontal and then it started the calibration. I hadn’t the preview on. So I didn’t take pictures. I will test a few things the next days to see if there’s something interfering. I’ll give you an update then. |

Simply I just don't understand how you can have an inverted image in live preview when using our test MP4 video files and why do you have to invert it this way or that to correct it? What video player offers such an option and where it is available? Is the image also inverted on TV and looks the same as in the grabber preview? |

I downloaded the file to my iPhone. Saved it to the gallery. In the photos app it is possible to flip the video. In the gallery I play the video and watch it via airplay on my Apple TV. Here you can see the preview in my download folder. There is it how I downloaded it. UPDATE:

Just play the original MP4 test video on your Apple TV without using the phone to download it or playing it, probable it flipped the video this time vertically. Maybe it depends on the phone orientation. |

Downloaded it again. Now it works like charm. |

Awawa-dev can this beta be used with Libreelec or do we need to wait for a new plugin? Thanks |

Thank you - super quick as always! Installed and all working ok apart from a small bug that I referenced in the discussion below. The suspend function in LE keeps the last grabbed screen active. |

Hmm...but the LEDs are turned off when LE is sleeping? The power management script is still there: https://github.com/awawa-dev/LibreELEC.tv/blob/libreelec-12.0-hyperhdr/packages/addons/service/hyperhdr/source/system.d/service.hyperhdr-power-mng.service |

No they are not turned off - when I suspend LE they stay active

So probably we need to test these commands again in LE12: #740 (reply in thread) |

@awawa-dev sorry for the delay, I have tested those commands and they work as they should :) If I revert to the previous plug in it works as expected and releases hyperhdr. |

I have the firmware dump. now what? can I send to you? |

How did you manage to do that?! |

well I hope I have something useful. I'm not to sure. I pulled from the chip. |

Please send it to my email (in my profile). I will try to locate EDID table. But from my experience with MS2131 changed EDID worked fine until you connect an external HDMI, then EDID was built dynamically which it beyond our reach. Also usually firmware has a checksum, sometimes it is important only for the flasher but sometimes chip may also perform validation. |

I have sent. but tbh it looks all gibberish. there is a second chip which I cannot read. (Atmel 24C02N) edit. managed to read 2nd chip over I2C. its just all FF FF FF I will have to leave you guys here. I have a lot of home projects I need to get to around the house. |

I have the pleasure of submitting another version for testing: HyperHDR 21 beta1. I hope you will find the new features & improvements interesting and useful.
The architecture has been rebuilt once again, this time focusing on further eliminating heavy dependencies from the past. In addition to lower resource consumption, you will definitely notice how much the installers have been slimmed down (they still contain all the necessary dependent components) and the HyperHDR application itself.
The DirectX grabber has been expanded with a multi-monitor option. You no longer have to use external applications to capture a second or third monitor. Do you still use them? So please make sure they provide full acceleration support by the graphics card as HyperHDR does including using pixel & vertex shaders to scale the textures before sending them from the graphics card memory to the computer so as not to block communication resources which can cause for example: performance drops in games. It is also the cheapest and most effective alternative to HDMI grabbers and splitters on Windows x64 platforms such as multimedia miniPCs with N100.
More about DirectX 11 grabber can be found here: https://github.com/awawa-dev/HyperHDR/wiki/DirectX-11-software-grabber
Another new feature that I think will be useful for many people is automatic tone mapping. In case you can't control it from outside via the application's API this is the solution for you. Once enabled HyperHDR will analyze the video image and enable it automatically for dark and faded raw HDR signal and disable it when it detects bright SDR image with normal colors.

If you own Elgato HD60X make sure you read it
In the past, the process of calibrating the grabber's LUT to obtain the best possible colors was quite problematic: to do it, it usually required a PC set. HyperHDR v21 introduces a small revolution here because now all you have to do is play the calibration MP4 file in your favorite player and HyperHDR will take care of the rest. Thanks to this, we calibrate not only the grabber and TV, but also your default video player. HyperHDR was also the first to introduce support for the NV12 codec for flatbuffers, which opened completely new perspectives for the calibration of external systems because standard RGB flatbuffer stream was usually already processed at the source.
You can find more about the new LUT calibration using MP4 files here: https://github.com/awawa-dev/HyperHDR/wiki/lut-calibration
I am also pleased to announce for the first time support for the 10-bit P010 codec, which is already appearing in increasingly cheaper grabbers such as the UGreen 25173 (which can only gain in attractiveness after what happened with ELgato HD60X, more: Elgato dirty tricks with the HD60X model ⚠️ #1010). While it does not contribute much to SDR signals, it changes the situation a lot when it comes to HDR by expanding the default narrow bandwidth range above the standard 8-bits, minimizing the quantization effect. Another advantage is that it is usually a raw signal not damaged by the grabber trying to process the HDR signal as SDR. The format is supported by default by Windows, and when it comes to Linux, I created a patch for the UVC module so that it also works on this system.
The HyperHDR image already has a patch for P010. Note that it is based on the newer Bookworm so configuring wifi via wpa_supplicant will no longer work: for this you need to use the Raspberry PI imager installer (wpa_supplicant autoconfigure removed in bookworm but not replaced with other mechanism raspberrypi/bookworm-feedback#72). For Raspberry Pi 3b and Zero 2W users, I would like to remind you about a bug in the Raspberry Pi kernel that can cause incorrect display of colors on Bookworm (RPi 3b & zero 2 kernel bug: swapped colors ⚠️ #848).
More about support for the P010 format can be found here: https://github.com/awawa-dev/HyperHDR/wiki/p010-video-format
