Code erroring out

[lawrencestroud]

Hi, I am having a simple but strange error. I can get everything to work but the python script is erroring out. It can't find the file on line: check = sp.Popen(shlex.split("{0} devices".format(self.config["location"])), stdout=sp.PIPE, stderr=sp.PIPE). Exact error is "FileNotFoundError"

I have download adb, I can see my devices through the Powershell, I have set up the IP cam, I can the IP cam as a browser in OBS. The JSON is configured to the address of the adb.exe (and it's reading the JSON as it shows up in the debugger). Correct port (default of 8080).

same issue.

same issue.

Easy enough to resolve this error. Add , shell=True as an argument within the end of the brackets. You'll need to repeat this later in the code. But having said all that, the code ran and did nothing. It couldn't detect any devices via adb when I can clearly see them in Powershell. Conclusion: I gave up. If you have any better luck, please share! There is an obvious gap in the market here for some simple code to convert a phone into a webcam (and all the versions on the web , DroidCam / IVcam etc are inconsistent or plain right dodgy pieces of software).

@lawrencestroud @utsawb1
Can you post the config you use? My guess is that you may not have formatted the path to the ADB executable correctly: if you have the path C:\Users\tester\adb\adb.exe you would need the path in the config file to look like C:\\Users\\tester\\adb\\adb.exe

I'm also hesitant to use shell=True because it's considered insecure.

Hi @HunterAP23 - I'm running into the same issue with my config set up like this:
{ "location": "C:\\Users\\Victor\\Downloads\\platform-tools\\adb.exe", "port": "8080" }
The forwarder and platform tools are here:

Having added shell=True to the two sp.Popen calls has made it run somewhat farther, but now it stalls on my ADB being invalid. The ADB is a fresh download, I'm not sure why it'd be invalid. I've had apps like Iriun Webcam (which I suspect does exactly this) running perfectly on this computer + phone. The error still occurs when I switch to use the ADB that came with Iriun.

Going to rework and refactor some things - I'll follow up when I release some updates and see if the issues are fixed.

Excited to see what you come up with, it'd be great to have something like this actually functional.
It's mind-blowing to me how there's not a single app/program out there that just offers a USB feed plus basic camera controls (manual exposure, focus lock, that sort of thing). I was thinking I'd probably be able to extend this myself to get the camera controls I'm looking for exposed.
Would you happen to have any idea how soon you'd be able to take a look at this? Days, weeks?
Appreciate the effort, and that you put this out here in the first place!

The issue with getting camera controls accessible over USB is that it's not possible to access hardware on Android devices in that way. It would essentially require one app on desktop and another on the device itself to communicate over a network connection, where the device app opens the hardware camera and the desktop app receives the camera feed. I'm not an Android programmer but I was toying with the idea of doing this, but it'll take quite a bit of work (a few months for me).

I'm working on it as we speak, I'm expecting to actually get it done by later today/tonight (I'm US eastern time). This app's been needing a good rewrite for some time now.

I hadn't considered that - I had just assumed that there would be pre-existing hooks/function calls for that sort of thing over the debug connection, but it's not surprising that that's not the case.
I imagine it'd be easier to do something like this if the controls were phone-side, rather than the phone being controlled from the desktop... Maybe I'll give something like that a shot. I'm entirely unfamiliar with software/application programming as all my experience is in the game-dev space, but who knows, maybe I'll be able to figure it out.

Looking forward to giving it another shot once you've done your rewrite though!

For a completely different awful idea - do you think it'd be possible to handle my camera controls etc. through a regular camera app on my phone, so that the sensor and image processing settings are set to what I want, and to still be able to use this to stream the final result to the PC?

You know if you use the IP Webcam app that you can access the web GUI for that camera instance through a URL right?
The README provides an example of this in steps 13-16, but this assumes you're using the IP Webcam app on your device

I created a new branch called testing where I've posted the updated code for the project. Please try it out and let me know if it works as expected.

I did actually know that, and I've got it set up - I don't know why I blanked on this, but just completely forgot while typing these comments. That does indeed solve that 'issue'.

I'll give it a shot sometime today!
