cloud-game's Issues

Gameboy supports fullscreen + option to toggle gameboy and debug index

External config

Would be great to have some kind of external configuration file to read in runtime.

It seems that 169.254.169.254:80 is down.

Please remove the ROMs to prevent this from being taken down

Including ROMs on the github will get Nintendo or other developers on your asses in no time. Please remove them so this won't be taken down within a week.

IOS Support

Investigate why IOS chrome browser doesn't work while Android is working. Refer to https://github.com/pion/webrtc/tree/master/examples/sfu-minimal

Colors seem different

Colors seem different from RetroArch, as example:
this:

RetroArch:

Improve performance

Expectation:
ping 10 in the same country (Singapore - Singapore host) (USWest - Seattle/ Los Angeles)
Ping 50 to the other nearby country (Singapore - Vietnam)

it crash when use libretro

when i used libretro about ps2 core, it crashed. i even doubt it is a core problem, but i tried the same core in retroarch, i workd without crash. the crash program is overworker, it may crash from cgo think.
golang output is at pkg/emulator/libretro/nanoarch/nanoarch.go:367. it says receive a unreconginze signal.

c++ output is the following sentence:

Clean up Commit History

It seems like the commit history contains some test commits that are not relevant. Like the commits here - https://github.com/giongto35/cloud-game/commits?author=torvalds.

It's not a good practice having commits like this, that uses some other usernames.
Please clean up commit history-related this. Thanks.

Touch-screen gaming experience

Refactor ws and http index file share logic

Experience with 4k resolution

Try scaling game output to 4k resolution and experience the latency. It's good to push the limit and see how much the infrastructure can provide.

Removing the 3 playstation BIOS

Since they are copyrighted, it's better to remove them from the repo.

Self-update, Libretro cores downloader / updater

I was wondering whether it'd be useful to have libretro core downloader / updater inside overworkers based on sys.GOOS rather than using manual assets and hard coded dynamic lib names (so, dll, ...):

Remove all the cores from the repo assets
Download static worker binary
Either auto-download needed cores during the first run or exec worker -download-cores
Download cores based on the current system by sys.GOOS -> kinda http://buildbot.libretro.com/nightly/{OS}/x86_64/latest/
Load cores with the extension based on sys.GOOS
4.5 Possible auto-updater: worker -update-cores
Profit

Improve load balance to consider memory resource

The current implementation is only based on latency from user to each worker only. Each time a user connects to the master server (overlord), overlord will return all the addresses of workers and ask the user to fetch all latency to them. This latency check in the browser is conducted by an HTTP request to worker through /echo/ endpoint.

Overlord logic to return addresses list:
https://github.com/giongto35/cloud-game/blob/master/overlord/handlers.go#L201

Client logic to check all latency
https://github.com/giongto35/cloud-game/blob/master/static/js/ws.js#L88

The current implementation lacks:

Check the if memory resource of worker is still higher than some threshold (or number of GoRoutine doesn't reach some limit), to assign game session to it.
Among all valid servers ( <= 100ms ping and have enough memory resource), we do round robin assignment.

Track ping and data

Track ping and the gap between input and media stream to front-end

Data race at gameview keypressed

2 GoRoutines spawn in the same time

ListenToInputChannel writes keyPressed
Update reads keyPressed

3 approaches:

Add lock to keyPressed (seems overkill and not natural)
In update loop, select input event. Exetremely slow because of frequently channel polling.
Let it be

Add context to manage sessions

Add context to manager request response sessions

Encode logic comes from github.com/pions/asciirtc

Update UI to be more mobile-friendly and maximize game screen.

Any proposal for front-end will be welcome. We can set a plan to improve UI based on that design.

Mobile touch joystick

Joystick touch on mobile

Collaborative gameplay

Is it possible for two people to play in the same room? If so, I would like to request, and possibly help implement this feature. I imagine that the inputs from both clients would be sent such that a single game is controlled by both.
Thank you!

[GBA] mGBA Pokemon Gold overworker crash on exit

Pokemon Gold (Pokemon - Gold Version (UE) [C][!].gbc) crashes with segfault on the latests mgba core when you click "quit" button on the site.
Maybe it is worth to research (:/ further.

I1008 20:35:15.253389    5468 handlers.go:311] Unregister server from overlord

[bug] The server returns a bunch of duplicate addresses for the ping check

It seems the server unnecessary duplicates addresses for latencyCheck. Is this a bug (I haven't looked at this part yet)?
As example, two overworkers on localhost:

And here is current cloudretro.io:

Not work on Mac OS. dlopen error.

error loading assets/emulator/libretro/cores/mgba_libretro.so, err 100

Pokemon Gold Emulates with a odd screen

When trying to load Pokemon Gold ROM its graphics load oddly in a broken manner. Not sure if this is a ROM or emulator issue or something else, but worth looking into to make sure it can handle different ROMs.

Build Binary with static file (pack with go bindata)

https://github.com/go-bindata/go-bindata
GOOS=windows GOARCH=amd64 go build -ldflags -H=windowsgui

Move away from WebRTC DataChannel, using socket for game input.

WebRTC Datachannel has some bug (when the connection disconnect abnormally)
ortc ERROR: 2019/10/23 19:24:00 Failed to accept data channel: unexpected packet type: WebRTC #Binary
In addition, WebRTC Datachannel seems not be currently supported by some browser.
Because game input payload is small, better use WebSocket for input.

Proposal: Split binaries for overlordhost and overlord into separate binary

Currently, cloud-game generates only one binary for both the program included in a single binary. While running we have to explicitly set flags to indicate which mode we intend it to run.
I am suggesting to split the two binaries into two different executables. They might share some of the same library packages but should live in different executables. I think there are some benefits - like -

1. we could include runtime flags specific to one program,
2. We could do different versioning for overlordhost and overlord,
3. one executable doesn't include the life cycle of the other one.

Here is some package restructure proposal that I think would suit nicely

cloud-game
|-- assets     // includes all static .so or game file
|-- assests/games
|-- assests/lib

|-- cmd         // will include all the executables
|-- cmd/overlord  // will include the main.go for overlord. can use spf13/cobra
|-- cmd/overlordhost  // main.go for overlordhost

|-- docs      // includes all the static docs
|-- docs/design
|-- docs/userguide
|-- docs/site    // includes static site pages for projects

|-- hack       // Includes various scripts, build files
|-- hack/docker // includes docker build files
|-- hack/config  // includes various config files like prometheus.conf
|-- hack/k8s    // includes k8s runtime files
|-- hac/scripts  // various scripts to build env or others

|-- pkg  // includes all go/ cgo librarie codes. ie-
|-- pkg/api
|-- pkg/util
|-- pkg/config
|-- pkg/webrtc

| -- static   // include project-level static resources like the logo
| -- static/logo
| -- static

|-- web      // all the files for the web frontend
|-- web/

|-- vendor // go vendor directory

|-- Makefiles
|-- go.mod
|-- go.sum
|-- README.md

@giongto35 Let me know what you think about this? I can go forward with a PR if it seems okay. Thanks for this awesome project. 😄

Close room after no more session.

hello Giongto

hello giongto, it makes me happy to see and see that your project and the ideas I had and you told me a few months ago, come true ... ok now seeing the structure ... some questions arise.
regardless of the server where you are staying .. example a powerful one can I run demanding games say (ps2, xbox, xbox 360, game cube,? and another question can I add a frontend "launchbox" to the environment?

Stream game to twitch

Integrate with Twitch API to stream game to Twitch, hence can gain more exposure.

Have any plan support the android emulator?

I'am very appreciate this project

Audio streaming

I was trying to make audio streaming work (again) and it is kinda working now. It's synced with the video but overly compressed for some reason (see example on the video down below).

So, here what I fixed so far:

it seems that non-blocking select-default goroutine in the emulator audio samples pusher drops a fair amount of samples here. Tried it without select and it pushes all samples now. For the testing I wrote a simple function, which writes raw PCM samples into a file and then played it in the Audacity (Import -> Raw).
I excluded resampler and used nestopia core because it runs in 48kHz audio rate to not to worry about resampling for Opus (which needs to be checked)
I'm not quite sure why there is int16 to float32 sample conversion, Opus encoder by default operates with int16. When I tried to play saved float32 samples they were overly clipped or loud distorted, maybe I just saved it wrong, but I switched GO channel into int16 and it works fine.
next I checked that Opus encoded frames before push into WebRTC are legit and they are, checked by decoding, saving to pcm, and playing.
the last bit in the webrtc.go where RTP audio packets are made. It seems the length of the payload should be equal (see the doc) to the length of the encoded audio frame (for 2.5ms/48kHz it's 120 and so on) and not to the length of raw Opus encoded bytes as it is right now.

After these fixes I was able to run the app with sound, but it's distorted. I think there is something with RTP opus packets or something on the client-side. No idea what to do next.
Maybe you have some (:?

Raw video with example (it's loud)

The second session will send input as second player

URI encode / decode JS bug for the latest room changes

When escape function in the controller.js:

copyToClipboard(window.location.href.split('?')[0] + `?id=${escape(roomID)}`)

escapes roomId___gameName then result link contains escaped characters for ;,/?:@&=+$, as example:

Legend of Zelda, The - A Link To The Past Four Swords (U) [!] -> 
Legend%20of%20Zelda%2C%20The%20-%20A%20Link%20To%20The%20Past%20Four%20Swords%20(U)%20%5B!%5D

but corresponding parser uses decodeURI function, which leaves described above characters escaped, so on the server side it won't find the game by its name and a worker just crashes:

I1022 17:06:32.121056   11960 browser.go:88] Received room response from browser:  5e3024468942a6fd___Legend of Zelda%2C The - A Link To The Past Four Swords (U) [!]

I1022 17:06:32.122056   11812 nanoarch.go:237] error loading , err 34

It can be fixed by using decodeURIComponent function instead.
I've already fixed it in the new frontend, but not sure when I'll be ready to PR, so wanna let you know about this bug.

Lag after the game is reset

Save game state to cloud and overlord. Next time can rejoin

The instance can be respawned, so better store states on some cloud storage.

can not see rom list.

i had launch server and saw the website, but i can not see rom list. why?

UI Enhancement

Add aspect ratio support

Added proper nearest neighbour up/downscaling support with aspect ratio calculation.
Now it sets the initial viewport (output image) resolution to the base resolution from the loaded core upscaled by 2 to remove resampling artefacts (as on pictures below). So the manual resolution config for each core now removed completely.
A Sony BIOS intro now is being shown properly.
Need some testing.

Before

After

Local host can be connected over internet

There are host A, local host B and overlord(Master handles all session)

A person Y host a game on local host B with room_ID K
A person X connecting to host A. Person X enter room_ID K.
Host A inform person X to create new offer. Offer is sent to overlord -> local host B (by websocket event)
Localhost creates new webRTC session based on the offer, attach to the room with roomID K. SDP is sent back from localhost to overlord and from overlord to Host A.
Browser create new peerconnection based on the SDP.

Host A maintains 1 single websocket connection with X. When X change room, the WS connection is still there, only the peer connection is updated.
It means: A WS session from host A to X can handle peerconnection to different host Y!! .

WebRTC ice candidate errors

If you add ice candidates error handler, i.e.:

    pc.onicecandidateerror = (error) => {
        console.error(error);
    }

a bunch of messages will be shown in the console later

Does anyone have same errors with this handler or is it just an issue with my dev environment?

Possible bug with touch high frequency tap

Possible bug with the touch input. Seems it can't process fast button tapping for some reason.
Tested just in the Chrome desktop.

controller map is not same among platforms

Audio support

It seems there is no audio when you run games on the cloudretro.io or locally.
Maybe I missed that point in the docs, but does it support audio decode/playback right now?
Tried the latests versions:
W10 / Chrome (Stable, Dev, Canary),
Ubuntu 18 / Chrome (Stable),
Android 8 / Chrome (Stable).

Reduce usages of CGo

There are a lot of c codes hardly coupled with the go codes. https://dave.cheney.net/2016/01/18/cgo-is-not-go. It is better to use to go as much as possible. I think there are some scopes to reduce some cgo codes. Let me know what is your thought about reducing the uses of cgo.

Show number of players is joining the same room

To enhance the collaborative playing experience. Need to show the number of players in the room + the ping from client to server.
The number is under share button

Add Integration test

Test 1: On Single server

Connect to server
Create a room
Send input

Test 2: On collaborative hosting

Spawn Coordinator
Spawn 2 server
One server create a room. Get the room ID
The other server try to connect with the roomID
