Testing latest commits and test with MacOS.

[fpmweb]

Hello xerpi,

I have compiled your latest commits to see if it could work on my Mac but it doesn't work either :( If I can help you solve the problem for Mac, tell me where to look and I will help you.

Thanks for your time and your great work.

My test with lsub on Mac (macOS Catalina):

Bus 020 Device 019: ID 054c:1337 Sony Corporation PSVita Serial: UDCD UVC

and lsub -vd:

            PSVita:

              Product ID: 0x1337
              Vendor ID: 0x054c  (Sony Corporation)
              Version: 1.00
              Serial Number: UDCD UVC
              Speed: Up to 480 Mb/s
              Manufacturer: SONY
              Location ID: 0x14210000 / 19
              Current Available (mA): 500
              Current Required (mA): 500
              Extra Operating Current (mA): 0

And with dmesg:

PSVita@14210000 <class AppleUSBDevice, id 0x10000850c, registered, matched, active, busy 0 (1 ms), retain 15>

Hi, I installed a macOS VM and tried to debug why it doesn't work on macOS but I didn't manage to find the cause :(

[fpmweb]

First of all, thanks for your time. It's a shame that your plugin doesn't work on MacOS. The truth is that it is a great plugin and many people in the scene expect it. If I can review something from my Mac you just have to tell me.

Thanks xerpi!

"Mac UVC driver is expecting some kind of info from 0x84(UVC_GET_RES)" Do you remember that? https://www.reddit.com/r/vitahacks/comments/95256o/poc_v6_psvita_usb_streaming_uvc_usb_video_class/ Maybe this will help you

[xerpi]

I've forgotten about that! I'll try to implement that request, but I don't have a Mac so I need testers.

[Rydgel]

I can help testing too, I have a mac and know how to compile stuff

[tetsuoScene]

Xerpi, I have a MAC and I have the development environment ready to do git pull, compile and test ;)

[xerpi]

I'm a bit busy during workdays, so to debug do the following:

• Remove the plugin from the tai config (don't load it automatically)
• Compile this plugin with make DEBUG=1
• Run make DEBUG=1 send to send via FTP the plugin to ux0:data/tai/kplugin.skprx
• Install this kernel plugin-loader VPK
  • It will open FTP on port 1337
  • It listens for any data on port 1338, and if it receives a connection it loads the plugin. So from your PC you can run nc -zv $PSVITAIP 1338 and it will load the plugin, located in ux0:data/tai/kplugin.skprx. This way you don't have to exit the VPK to run a new compilation.
• The debug version of UDCD UVC prints debug info on the screen and also to a file if you uncomment this (do it)

If you have done that, open the video player on Mac and paste here the generated log found at ux0:dump/udcd_uvc_log.txt.

[tetsuoScene]

Ok, I'll try.

By the way, consider putting the PS VITA. This would be the request: make DEBUG=1 PSVITAIP=XXX.XXX.X.X send

[tetsuoScene]

[xerpi]

That's interesting because I don't see why UVC_GET_RES (0x84) being sent.

Maybe the problem is that macOS doesn't support NV12 frames?

[tetsuoScene]

I don’t think that’s a problem.

I am attaching the log file with one more test: udcd_uvc_log.txt

[xerpi]

The logs look good to me... Can you try changing this line:https://github.com/xerpi/vita-udcd-uvc/blob/master/include/usb_descriptors.h#L116 to UVC_GUID_FORMAT_YUY2?

[tetsuoScene]

Done, but don't work. New log file: udcd_uvc_log.txt

[AaronFatalis]

Following this, would love to get this to work on my Mac, so I can offer testing from my end as well, just instruct me on what I need to provide to assist.

[tetsuoScene]

If you need anything. Here I'm to try.

Thanks!

[AuroraWright]

@xerpi not sure if that's of any help but I have 2 UVC devices (a webcam and a capture card) which do work on Mac, I posted a lsusb of both here https://github.com/xerpi/vita-udcd-uvc/issues/4#issuecomment-593750722 . If you want to, I can also try dumping their traffic using this https://aud1os.wordpress.com/2017/10/22/usb-monitoring-with-wireshark/ (never used wireshark before tbh) and/or the Vita traffic

[Mich-Cr]

help hello good afternoon we are June 9, 2020 any solution to use udcd-uvc on mac?

[tetsuoScene]

No, doesn't work on mac :(

[csutedja]

is there going to be a fix?

[xerpi]

For now you can use Parallels to run a small Linux distro on macOS...

[xfangfang]

Here's a version that works for MacOS, but there's a problem with it (two columns of pixels on the left of each frame appear on the right side of the screen)

Anyone interested in fixing this problem can see this pr: vita-udcd-uvc/pull/72

vita-udcd-uvc-builds-for-mac

[xerpi]

Thanks to @xfangfang for discovering the potential issue! I've pushed new commits to master. Can you try if this version works on macOS? It works fine on Android. udcd_uvc.zip

[xfangfang]

It works！

[dochardware]

works for me. thanks!

Good job everyone!
