osu! iPad transport - Turns your iPad into osu tablet!

I've started working on this yesterday. osu! iPad transport is basically 2 apps working together to allow you play osu! on your beloved iPad.

1. Server - Serves frame and audio data, also handles touch commands received from the client (no keyboard support yet).
2. Client - Fetches and renders frame and audio data from the server and sends touch commands.

Everything is going over WiFi (802.11n recommended) at 40 - 60fps. This is only limited by data throughput.
I will improve performance in near future by eliminating need to compress stream with JPEG and implementing motion estimation, so I could stream PNG compressed differences between X amount of frames.

Here's a sample video of quick client I wrote for testing the server (streaming osu! off different PC over WiFi):




More updates soon.

This will have a huge input lag, why do you even bother? Try using Syngery and play osu! on the other PC over the network and you will see that the input lag becomes a huge problem on insane difficulties.

Lol, something like this is obvious. Synergy isn't optimized for gaming.
I'm confident I can reduce latency to ~25ms and try to compensate for it.
(I only need to send up to 9 bytes of data per touch)

If not, I'll tunnel this for jailbreak users via USB.

If not 1. Lol.
These guys don't know what motion estimation is. They just stream pure frames.
Another thing is that they want to reduce resource usage, so something higher than 5-10fps isn't possible.
For 60fps I have to capture frames every 0.01s. Here on my config CPU usage doesn't go higher than 35% and memory usage doesn't go higher than 100 MB, but I have relatively high-end rig.

Anyway, what resolution are you testing it on? Not everyone play on the same resolution and it can make difference, if I play on 2560x1440 and you test it on something like 1024x768 because there's a huge difference between transfer bandwith etc.

Doesn't seem like he is gonna follow through or he just hasn't made any sort of progress really a shame.

This would be pretty sweet, but if I understand correctly, this would probably require kernel or OS modification to make the port on the iPad function like this?

I was interested in a program like this, for Android, that would use the USB, but the port on the tablet itself, by default, has very limited possibilities as to what it can do (some devices can do USB Mass Media, and service mode to flash firmware, Samsung devices can do KIES, etc).

Android 2.2+ has support for USB devices (I think), but in order for this to be possible, the kernel (and possibly USB drivers) will have to be modified to reflect this, and a proper adapter/cable would have to be made. This also in some cases requires the manufacturer of the device to give out the source for that particular device, or another similar device.

I don't know how Apple's port on iOS devices work, but if I had to guess, it is probably limited to USB Mass Storage only when communicating with a computer, and nothing more advanced then that.

Yeah I know of how it could be done but there is like no updates from bag about anything I clearly think he is either not going to bother or something

Well, I have some primitive iOS client already.
Still no touch support.

I'm not dropping this, I'm busy with work every now and then.

keep up the good work I guess (good work is work on this, bad work is your work every now and then that keeps you busy from doing good work, good. work!)

Because I am going to use my high performance streaming method in commercial products as well.
