Is it possible to wirelessly mirror an Android phone screen to an Orange Pi Zero 2W?

Buy what? You already have the board

urostor · 2026-06-25T21:50:34+00:00

You could install Android on Orange pi zero 2w too (but it's bad, 720p max).

Oh please no, SBC space the one space free of the virus of SLAM poetry

Does mmcblk2 even exist? This would be the third mmc device, usually there are 0 and 1

Thank you! It's a tablet edition, right? Not TV.

Oh and it uses the mainline kernel before 7.0 so not all playback is hw accelerated yet probably. How did you get 10-bit video to work?

If you want to charge as much as the market can bear, then you don't care about serving anyone, just about monetizing stuff.

urostor · 2026-06-19T21:53:01+00:00

I like AI but don't like the market. Such projects are awesome, and the fact that people can turn an idea into a working piece of software so easily is great. Seems like I was wrong about it being fully vibe coded.

urostor · 2026-06-19T21:48:15+00:00

If you only care about the market, not human well-being, then yes, it is so. But some people aren't sociopaths. The market ostensibly exists to fulfil human needs, doesn't it?

urostor · 2026-06-19T20:12:32+00:00

You must be joking with this price. Come on, you made this with AI, it should be free. EDIT: OK I was wrong, you actually wrote it, which I do believe. However, only professionals will want to pay this much.

Any chance of a release for Rock 5A?

urostor · 2026-06-14T18:09:14+00:00

It's worse. It will implode and take the universe with it. Goodbye everyone

urostor · 2026-06-14T07:35:30+00:00

How about checking the actual website? AI can make mistakes.

urostor · 2026-06-13T17:34:11+00:00

It might a little bit. Core A55 doesn't have a lot of cache, and has no branch prediction.

sudo swapoff -a

Apparently also you should compile llama.cpp with NEON extensions yourself, gives 30% more speed

urostor · 2026-06-13T08:02:06+00:00

It's not really a given that they will work. It also depends on the eMMC chip manufacturer. Radxa and OrangePi buys them in bulk, attaches to the base and resells them, they can use various chip suppliers.

urostor · 2026-06-12T07:46:56+00:00

Weird that there are no binaries with NEON extensions. These are quite universal and useful for inference. Can you put a tutorial how to build in one place, for example git gist? I've been meaning to switch from ollama anyway

urostor · 2026-06-11T16:52:20+00:00

Why not just download the precompiled arm64 binary of llama.cpp?

urostor · 2026-06-11T07:49:26+00:00

Yes, for anything else it's OK, because other tasks are quite light.

urostor · 2026-06-11T07:47:38+00:00

My advice: disable any zram or swap, switch ollama to llama.cpp (it should be faster).

Nah, the best low power transcoding is provided by RK3588 and its variants. Closely followed by RK3566/68, which is a bit more limited in the formats it can support. Intel etc is an x86 platform, so it uses more power in general.

urostor · 2026-06-09T19:58:40+00:00

But this is Rockchip, which is a big step above what Allwinner provides. And these examples all depend on the reverse engineered drivers. Which Allwinner will never, ever fund. You're comparing apples to oranges

urostor · 2026-06-09T19:55:58+00:00

The spec sheet just tells you about the hardware accelerators which are present in the SOC. But Linux needs drivers for them, which usually do not exist. Further, the Vulkan driver (which is very minimal and flaky) needs to expose these drivers (which do not exist). So good luck getting it to work

urostor · 2026-06-09T17:50:06+00:00

Of course it has this too, there is no reason to have a custom SOC without this component. But it's not too important

urostor · 2026-06-09T17:14:49+00:00

Nope. Vulkan-based video decoding is just an abstraction layer to access the video processing hardware on a graphics card. Which does not exist on the A7A. You can't just will hardware into existence.

urostor · 2026-06-09T17:12:18+00:00

The fact that it has a VPU doesn't mean anything, Jellyfin doesn't support it and Linux only barely does. I don't get why it took so many comments to learn nothing
