netristv/ws-qvh

Server for streaming the screen of iOS devices over WebSocket.

ws qvh

Web Socket server for streaming the screen of iOS devices.

How it works?

1. danielpaulus/quicktime_video_hack - video streaming
2. appium/WebDriverAgent - device control
3. NetrisTV/ws-scrcpy - user interface
4. NetrisTV/ws-qvh - forwards the video stream over Web Socket

Steps to set up

1. Get macOS (streaming only should also work on GNU/Linux)
2. Connect a device, accept "Trust This Computer".
3. Verify that you can record your device screen with QuickTime
4. Install danielpaulus/quicktime_video_hack and verify that you can record your device screen with it
5. Build sources: go build. This command will produce ws-qvh binary.
6. Make sure your ws-qvh binary is available via the PATH environment variable.
7. Setup and run ws-scrcpy. Follow the instructions here.
8. Open link provided by ws-scrcpy in your browser.

Notes

• Only video stream is transmitted (no audio).
• WebDriverAgent can be started only after the start of video transmission (i.e. quicktime interface activation).
• WebDriverAgent can take a long time to start.
• Control capabilities are very limited (compared to scrcpy/ws-scrcpy):
  • single tap
  • home button click
  • swipe (this command will be sent only after the gesture is complete)
• No way to customize stream parameters (bitrate, fps, video size, etc.)

ws-qvh's Issues

Unable to get screen frames on ios 16

I forked this project, and change qvh module to code version of externalizeGST branch fixing gstream issue. While I'm using ws-qvh with ws-scrcpy with USE_QVH_SERVER enabled. I found it can get datas from ios 14 and ios 15, but not ios 16.

Versions:

Here are versions I'm using:

• quicktime_video_hack: https://github.com/chenhengjie123/quicktime_video_hack (based on https://github.com/danielpaulus/quicktime_video_hack/tree/externalizeGST, only add some logs for troubleshooting. )

• ws-qvh: https://github.com/chenhengjie123/ws-qvh (based on https://github.com/NetrisTV/ws-qvh. Only add logs for troubleshooting and change quicktime_video_hack to version above)

• ws-scrcpy: https://github.com/chenhengjie123/ws-scrcpy/tree/feat-20230302-testOnWsscrcpy (based on https://github.com/NetrisTV/ws-scrcpy, Only add logs to output ws-qvh stdout and stderr to console)

• mac os version: 12.1(21C52)

• go version: go version go1.17 darwin/amd64

• node version: v14.16.0

Steps to reproduce

1. Clone and build ws-qvh using command go build, then got ws-qvh binary file.
2. Add ws-qvh file to environment variable PATH
3. Connect ios device to mac.
4. Start ws-scrcpy using code version https://github.com/chenhengjie123/ws-scrcpy/tree/feat-20230302-testOnWsscrcpy using command npm install && npm start
5. Open http://127.0.0.1:8000/ , select the ios device and open its remote control module:
   

On ios 14, 15, the screen content can appear normally like below:

But on ios 16.0, 16.1.1, the screen content did not appear:

From ws messages in screenshot, it seems no data came from server side.

Logs from server side

On iOS 14 or 15, I can get screen frames successfully and quickly, here are logs(most of them are logs from ws-qvh):

logs-on-ios-15.log

While on ios 16, it stuck while reading lengthBuffer like below:

logs-on-ios-16.1.1.log

ws-qvh not working for ios 14.6 and above

ws-qvh not working for ios 14.5 and above.

possible to use mjpeg server as optional.

Can't control the device from the UI

Hi,

Thanks for the great effort you've put. I can successfully connect and reach my device from "http://127.0.0.1:8080/" port and everything works perfectly.

However, I can't control the device from the UI, its not responding to my mouse clicks and swipes at all. I hope you can help me to figure out this problem.

I have this error popping out in every 2 seconds
handle_events: error: libusb: interrupted [code -10]

Thanks in advance!

WS-QVH buffer format and help

Hi Can you help me, how ws-qvh works and what format, it is buffering its raw data. so i can use AVFOUNDATION ios library to mimic same.

xcodebuild failed with code 65

Im getting this error after de qvh starts:
Im running appium test with no problem, but with ws-qvh im getting this error.
I have already check the possible fixes witht the setting the team to the WebDriverAgent and nothing.

ws-qvh in PATH environment, but not work.

I am stuck in "Steps to set up" steps 6th.

I'm sure ws-qvh config is correctly by "which ws-qvh" in Terminal, but when run ws-qvh in Terminal, ws-qvh crashed with following log:

ws-qvh not working on Ubuntu

ws-qvh is very cool and is working very well on Mac. I want it to be run on Ubuntu but fail. There is no video data output. I have tried to update to the latest quicktime_video_hack project. The output is the same.

Following is what I have done.

1. upgrade to latest quicktime_video_hack with 2 patch from ws-qvh
2. Modify main.go to fit with latest go-ios which must change go-ios/usbmux to go-ios/ios
3. build ws-qvh-new on ubuntu
   [on linux]
4. run sudo usbmuxd &
5. run idevicepair pair
6. run ws-qvh-new 0.0.0.0:8888
7. run modified simple web client with h246 renderer connect to ws://:8888
8. No video output. Find the console output for ws-qvh-new from below
9. Original ws-qvh is with same result.
10. I can stream video with ws-qvh & ws-qvh-new on mac.
