PSP Camera Support (Android)

[RinMaru]

Would we be seeing the PSP Camera supported soon so we can play EyePet and Invisimals with our webcams and mobile cameras?

[hrydgard]

It's certainly possible to do, but it may be quite a bit of reverse-engineering work to figure it all out - I don't even know for certain that anyone has figured out the camera APIs apart from the function names. There does seem to be a piece of homebrew using the camera floating around, but the links I could find just return 404...

[sum2012]

@hrydgard
JPCSP support camera,you can reference it

[hrydgard]

@sum2012 ah, I didn't realize. Well, certainly doable then...

[RinMaru]

Aw yeah ^_^ Go for it hrydgard cant wait to see some progress.

[zminhquanz]

and support UMD video

[RinMaru]

@zminhquanz That would be nice jpcsp supports it aswell. you may want to post this as a request unless @hrydgard dont mind having two requests in one thread. I could rename this as video and camera support. while we're at it add Animated banner support lol take your time hrydgard we appreciate your work.

@hrydgard, when ppsspp can access camera. So we can play invizimals or eyepet. I promise tu buy ppsspp gold if ppsspp can play invizimals or eyepet with camera mode. Thanx

[Endarko]

hopefully ppsspp in an upcoming version. there are features of the camera model

[Endarko]

ppsspp camera mode is very useful for the game pes

[Endarko]

please add ppsspp camera mode

[Endarko]

please

[Lyuu17]

Is there anyone working on this?

[hrydgard]

Yes, #9927 added basic support but there's still more to do.

[Endarko]

Please fix camera support for ppsspp. So we can play invizimals game

I would like to help with the issue but I have no clue on how to implement the sceUSBcam driver, i've seen others getting camera input in the emulator but I don't know how

[Florin9doi]

The camera is correctly displayed using Software Rendering and Frame Skipping:OFF, but it runs at 3 FPS:

[hrydgard]

Hm, that only works in software rendering? It should be possible for us to notify the FramebufferManager that a camera image is there - that way we could easily get this to work with hardware rendering. Should be looked into.

[Florin9doi]

Yes, Invizimals mix camera image and game overlay/hud only while using software rendering.
EyePet goes ingame with hardware rendering with no major graphical issues.

[unknownbrackets]

What address is the camera data being read into? Is it read directly to VRAM when the hud is mixed, or is it copied to VRAM later?

-[Unknown]

[Florin9doi]

Camera data is transfered using sceUsbCamReadVideoFrame (which pass a pointer) and sceUsbCamReadVideoFrameEnd (get the data length written in the meantime at that pointer): https://github.com/hrydgard/ppsspp/blob/master/Core/HLE/sceUsbCam.cpp#L118
I have no idea if the pointer is from vram

[hrydgard]

Right, and I forgot that those actually writes the image in JPEG format into the app's space. So we'll have to look into how the app does the JPEG decoding, maybe it decodes directly into a framebuffer then and we're not detecting it.

[Dgmtnz]

I've tried last build, but i have the same issue than before.

[hrydgard]

@Dgmtnz the text seems to be removed?

[hrydgard]

I screwed up a little bit. A new build is on its way.

[Dgmtnz]

Ok, last build gets the camera working perfectly, i'ts a little bit slow, but the game renders over it very nice, the only issue now is that you need a mic input in order to play the game

https://www.reddit.com/r/emulation/comments/cvw0nh/invizimals_camera_now_working_fine_just_need_mic/

[zackzick2]

Yes thats right. Mic function can make playing invizimals be perfect

I tried to implement microphone support
https://github.com/Florin9doi/ppsspp/commits/android_audio_record
but I'm unable to find how to unblock the current thread so another thread to be scheduled.
I think it may be related to this: __KernelWaitCurThread.
I'm posting this in case someone else is willing to continue.

[zackzick2]

Wooww good job. 👍👍👍👍👍

Good job 👍

[hrydgard]

PSP camera works!

Microphone is a separate issue. Let's make one: #12336

[ghost]

This will be added to v1.9 milestone?

[hrydgard]

Done, thanks for the reminder.

[hrydgard]

Although actually, we still don't support webcams on desktop computers. But I'll open a separate issue for that, too.

[Blane2609]

It's certainly possible to do, but it may be quite a bit of reverse-engineering work to figure it all out - I don't even know for certain that anyone has figured out the camera APIs apart from the function names.

Hi @hrydgard ,

Sorry for this unrelated question,
If I may please. Assume you have a mobile device supporting otg usb devices. Is it possible to run PS3jig on PPSSPP?

Kind regards,
Blane

[hrydgard]

@Blane2609 Our USB API implementation is very basic and we don't expose the USB port of the host device to it. Maybe one day..

@hrydgard Thank you for the reply. I appreciate all the efforts and work you are doing with PPSSPP.

[Costa1005]

So i tried to play invizimals with PPSSPP and it was going fine, but when i needed to use the camera it was very laggy, however it works fine with frontal camera, is this common?
