Orange PI boards support (H618 chipset) #1044
-
|
Hi, Yesterday I finally bought the equipment to set up my first Ambilight system for the living room (still waiting for the parts to arrive). Right now, I only have an Ambilight setup for my monitor (using a Pico and WS2812B), so my experience is pretty limited. I decided to go with an Orange Pi Zero 2W (based on the Allwinner H618 chipset, 1GB variant) as an alternative to the Raspberry Pi Zero 2W. I wanted to ask if I might run into any issues with the setup on the software side of things. I’m planning to use a minimal install of Armbian. Do I need to do anything extra to get it working (like enabling SPI pins, or stuff like that), or should it work out of the box after installing HyperHDR? Also, a newbie question: which GPIO pin should I use for the data line of the LED strip? I’m using an SK6812 and I’m a bit confused about whether I need to connect it to an SPI or PWM pin. Sorry for the basic questions my first time working with an SBC! Thanks in advance for any help! |

Yes, thats much better. Do V-Sync or max. FPS currently limit the output (the source is probably 24FPS for movies anyway, just to test max throughput)? QUIRK_ALTERNATIVE_DUMP_LOCATION does not always work (only for certain SoC) but it should limit the lag. |

Yup, limited to 30 FPS and VSync. No need for more than that tbh, might try a bit more.

With NV12 (v21beta1) CPU usage should be even lower. And without it you can't use advanced calibration because webos backend YUV to RGB conversion kills the details. |

I am still probably gonna use the Orange Pi for the HyperHDR server, and control the strip from the GPIO, I will try to use the capture card, but if it isnt very good, or I want to use signal detection and watch cable tv, i will use PicCap. |

If you follow this thread #896 you will see that webos with correct LUT calibration is almost equal to the best grabbers and is only beaten by the P010 format, but P010 is from a different league and requires an appropriate grabber and USB3.0. In any case, test both setups and choose the one that suits you best. |

Piccap with and without NV12 support. All thanks to using LUT: for 640x480x30fps for 320x180x60fps "https://github.com/awawa-dev/HyperHDR/pull/896#issuecomment-2365221973" |

Hi
At one time, when Raspberry Pi decided to focus on business clients and RPi SoC prices reached astronomical prices, I decided to investigate this topic. You can find the results on the blog: https://www.hyperhdr.eu/search/label/tvbox There was even some Allwinner there and I even built a newer kernel for it because Armbian abandoned it. If you find drivers for all devices on board (in the case of Orange Pi Zero 2W there is a big chance of that... and if the next Armbian update does not break something), the biggest problem is USB3.0 support, which on these devices is either unstable and/or slow. If you do not care about USB3.0, it should probably work, although for HyperHDR we definite…
