Hi,
I'm using a go binary built in my PC on Ubuntu 20.04. But getting the following error.

Kindly let me know if there is a way to resolve this.

The -backend-go gets rid of the USB error timeout but does not open the shutter either. Let me know if you would like some more info or to try something else.
Hi, I'm using Nikon D5100 and everything works fine but there is a problem. mtplvcap only captures 640x424 video quality. I wanted to see how I can get other qualities like full-HD as well.

I am using your program with OBS as per instruction as a webcam, but using OBS for just this is an overkill.
Would it be possible to send the same stream you are sending to websocket to the STDOUT? In this case, on Linux I would be able to pipe it to a virtual video device directly.

My Nikon Z5 successfully connects using mtplvcap-1.3.1 on Gentoo (5.10.27 kernel). The OBS packaging doesn't support building the browser source component until the still-officially-unreleased 27.0.1 EBUILD, and even then I can only get Firefox to recognize the (built-in, not plugin) virtual camera and not the Chromium-based Brave. Trying to manually set the F-stop throws ERROR lv: HandleControl: failed to set f-number: failed to set f-number: AccessDenied, and I don't know if I tested the ISO slider, but the other controls all work.
Thanks for providing the tool!
I tried the 1.5.0 binary and a local build from latest master. With both I get a SIGSEGV error when running the tool after granting it permissions via Security & Privacy. I'm using macOS 11.5.2 with an i7.

(hyphen instead of dot near the end)
it was the reason for the tool not working in my case

Hi:
Im trying to use my Nikon d5000 in my new mac mini M1.
When I get to the part of installing the dowloaded zip mtplvcap_macos_amd64.zip I get the attached message.
Also I can't access http://localhost:42839, which would be the camera controller.
I would very appreciate your help since i have not knowledge about coding.
Cheers.

Hello,
First of all, I'd like to confirm that Z9 does indeed work. I'm happy to provide you any data you want/need from it.
Secondly, I think I've found a small bug which doesn't affect anything.
In nikon.go there is a map where keys are camera names and values are their description.
For Z9 the product name from USB is NIKON DSC Z 9, for Z 7II the product name is NIKON DSC Z 7_2
So a slight change needed to make mtplvcap detect the model properly:
diff --git a/mtp/nikon.go b/mtp/nikon.go
index 2b24716..572aa66 100644
--- a/mtp/nikon.go
+++ b/mtp/nikon.go
@@ -182,12 +182,12 @@ var models = ModelMap{

I guess, the same change will be needed for some other newer models (like z6, z7, z6ii, z5, z50, zfc). But at the same time their parameters match the default so no real benefit of doing this.
It may also worth reimplementing camera model detection and may be rely on some ID.
Sadly, I have zero experience with usb or mtp so I'm pretty useless at proving patches here.
For D7000 the resolution reported is 4,928 x 3,264 (picture resolution) while actual live view is 640 × 424.
Is this the only possible resolution?
Camera is capable of 1,920 × 1,080 (24p) in video.
image is really dark and when you go on the web-browser the ISO is set to 0.
When you change it, it basically crashes and nothing else works from that point on, have to kill the camera to quit the application.
I tried to use it on my D300, but it did not work.

Prop 0xD1AC is the only way I know to change the resolution. Some models support reading/writing this. Some models only support reading. And others do not support neither reading nor writing.
According to a Nikon guy, there are many differences in MTP commands and props between DSLRs. Their public SDK may give me something interesting, but it's licensed under a proprietary agreement that is considered not to be compatible with GPL.
I'm having conversation with them and I may implement this feature after they released it licensed under a OSI-approved licenses.
After installation on Mac OS 10.15, the camera is not recognized by OBS or Skype.

I am trying to get mtplvcap working with my Nikon D5000 camera. It is connected to my desktop via USB, 0x0423 its ID (I have more than one MTP devices connected, therefore I specify that explicitly). Whenever and wherever I tried to run the software (I have Windows 10 and Arch Linux in dual-boot) I have one and the same error:

I do not have any possible interfering software running or any other drivers for my D5000 on both OS and still I continue to getting one and the same error.
I see that D5000 is in the list of supported cameras, just wandering what am I missing...
P.S. at the moment of [0000] INFO main: started I clearly hear camera shutter click and see that the diaphragm goes from completely opened to ~half closed position, and then I receive [0002] WARN lv: workerLV: failed to start live view: the camera is not ready
Hi,
I have a Nikon Z50 with the latest firmware. I just wanted to report that I'm able to use my Z50 with mtplvcap -max-resolution and get 1024x576 video at about 47-50 fps.
I was surprised to achieve this - especially since the Z50 only has a micro USB connector (which I'm assuming is USB 2.x speeds).
Sorry if this is not the right place for this report, but I wanted to pass along the feedback. Thank you for this project!
Hello there! First of all, thank you for creating such an awesome piece of software!
I'm having some trouble getting the OBS virtual camera to work on platforms like Google Meet and Zoom. I have a Nikon D5200. Here's my current config:
Any ideas on what the issue could be here? Thanks again!
I try build from source, but output many error.
but can't finish.
How to fix?
Sorry write poor English...

Hi I am using your program with nikon d5300 however it prints errors and no image from the camera in the browser.
What could be the error?
Also, during startup, the program take a picture(judging by the sound), but after some time a timeout error appears and errors begin to appear
I also tried the nikon webcam utility, but I also have no camera image in it.

Hey, I'm trying to get this working on debian with latest build from master but I'm getting this error:
ERROR mtp: fatal error LIBUSB_ERROR_TIMEOUT; closing connection
I have D5600, have you seen similar issues? What would be a good way to approach the issue?
I tried extending ModelMap by copying D5500 to D5600 config; still nothing.
D5500, that works fine with Nikon's own software (Webcam Utility) other than the obnoxious black borders all around the frame, which is why I wanted to try this.
brew install libusb went fine.
Running the binary (directly from Terminal) does not prompt for permission in any way, and nothing shows up in the Security & Privacy system prefs pane.
All I get output is:

Hi!
Thank you for this wonderful tool! Worked like a charm with D7000.
I've created an AUR package for Arch Linux

お世話になります。
D800EおよびD7000について
最下部掲載の環境にて無事に動作しましたので、
ご報告いたします。
以前試したD800E → HDMI → キャプチャーカード(Elgato, Cam Link 4K) → Win10
の構成では動作しなかったので諦めていました。ところが、
このソフトを使わせて頂いたことで、全て解決しました。
本当に、感動いたしました。
誠に感謝申し上げます。

Hi,
When following macOS 2.b.4 CGO_CFLAGS='-Wno-deprecated-declarations' go build ., the following error was displayed:
➜ mtplvcap git:(master) CGO_CFLAGS='-Wno-deprecated-declarations' go build .
go build github.com/hanwen/usb:
# pkg-config --cflags -- libusb-1.0
pkg-config: exec: "pkg-config": executable file not found in $PATH
go build github.com/google/gousb:
# pkg-config --cflags -- libusb-1.0
pkg-config: exec: "pkg-config": executable file not found in $PATH
adding pkg-config to macOS 2.b.1 fixed the issue
When camera is not connected and I start mtplvcap it is exiting, but if I just disconnect the camera while capturing it continue and just sending errors continuously:

can this support coolpix L24?

The shutter stays closed and the mirror up mode doesn't do anything either.
Hello,
First of all, the solution is working great with my D3300. It was simple to connect and provides noticeably less latency that using a capture card. My one question: Is it possible to achieve higher resolutions using this solution? Perhaps 720p or even the native 1080p for this camera?
Thanks

Commands I ran through:
unzip mtplvcap_macos_amd64
cd mtplvcap_macos_amd64
./mtplvcap
After I accept the binary file to be used in Security Settings panel, I get:
dyld: Library not loaded: /usr/local/opt/libusb/lib/libusb-1.0.0.dylib
Referenced from: [removed-path-but-this-is-in-my-downloads-directory]
Reason: image not found
zsh: abort ./mtplvcap
Also tried to build myself using source:
CGO_CFLAGS='-Wno-deprecated-declarations' go build .
Where I get:
# pkg-config --cflags -- libusb-1.0
Package libusb-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libusb-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libusb-1.0' found
pkg-config: exit status 1
# pkg-config --cflags -- libusb-1.0
Package libusb-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libusb-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libusb-1.0' found
pkg-config: exit status 1
I see that brew installled version 1.0.24 of libusb on my computer, so I believe that's the problem. How would I go about fixing it?

Switching to XGA does not work with mtplvcap. I also tested this with ptpwebcam on a Mac which actually worked.
I uploaded the camera info from ptpwebcam as camera.txt:
