I am wondering if I might be able to interface the tablet with a camera, be it using the composite input, USB or Bluetooth, and then recording it to the SD.
Would make a great reverse camera display to. Perhaps used for both forward facing DVR and reverse camera selection/split screen.
Any known hardware and apps that would allow this?
Or is there another ~7" tablet that has better inputs to suit this application?

Does anyone know if it's possible to access the forward-facing video camera via software oneself, even if the Video Call feature is not available on your network ? I work for at a hospital and as a "pet project" ( telemedicine ) one of the doctors who has a Kaiser would like to be able to video conference in with the forward facing camera. I would like to pursue this ( and I just might get a Kaiser for myself in the process..hint..hint ), and am curious if anyone has attempted to access the QCIF camera directly.
Any suggestions will be welcomed. Thank you.
Yes
open the camera application, the open the camera menu. (little bar below in the screen) lower line in the middle shows camera, press this button and the camera switch to the forward camera...
And if you want the front camera to start up by default, I scanned the registry and you should change the following:
HKEY_LOCAL_MACHINE --> software --> HTC --> Camera --> common
change the value of activecameraID from 1 to 2, voila front camera will start first.
offtopic: did anyone tried this already with an voip program and videovoiping? going to check it right away... Because it always starts the rear camera...
cheers
It doesn't work with MS Portrait
I have emailed MS regarding updates to Portrait and compatibility with front facing cameras. They replied saying they are aware of the Camera issue and that they would notify me of any updates.
I am not holding my breath... MS updates are few and far between compared to the rate of development achieved by some of the geniuses on here.
Thanks but....
Thanks for the replies, but I meant programmatically. I'm not trying to take pictures. I want to know where I can find information about how to programmatically access the camera, for a custom application that would run over 3G which would both stream video to the display, and capture and stream video out of the QCIF ....just as if the video call feature were available, but for networks where this is not possible.
As I said, this is for supporting a telemedicine application, that would allow the doctor to interact with a patient at bedside, when they are not physcially present.
For an application that would allow the video conferencing, you might want to consider MeBeam (www.mebeam.com). It's a flash based site that allows you to video conference with up to eight other people. I'm not sure if their flash application will be able to detect your hardware, but it's worth a shot.
So today I was messing with an old digital camera of mine and I had it connected to my PC and I noticed while it was connected windows was able to use it as a webcam even though the Camera had no mention of this as a feature at all. I was able to use it as a webcam on yahoo messenger and MSN messenger.
The digital camera is like a cheap 1.5 mp toy that can't even make videos. The question is would there be a way to someone maybe create a app or a driver that would allow windows/linux to use the camera as a webcam ?
DSLR Controller AFMA is an app made to assist Auto-Focus Micro-Adjustment calibration of your lenses on your Canon EOS bodies, based on the moiré method.
It is based on the code for DSLR Controller (XDA thread) and as such runs on the same devices and has the same connection capabilities. It can be download from Google Play. Of course, your camera must support Auto-Focus Micro-Adjustment for this to be useful at all.
It is currently in alpha stage. I'm releasing it in the currect state because I will be out of the country for a while, and I won't be able to finish it up further before I go. The manual seems long and daunting, but once you've used it once or twice, it really only takes a minute or so to set up.
You can play with it now for free. Fair warning, it wil probably transition to a (cheapish) paid product if it ends up being useful.
Read more in the quickly improvised manual which can be found on the DSLR Controller AFMA website.

Very nice idea!!!
But... I don't really get it.
Isn't the app supposed to alternatively focus using the AF module (which needs to be calibrated) and using LiveView?
When I start the calibration it quickly fully defocuses to nearest and to infinity and keeps doing something - but it does not focus using the AF module (or quick AF)...
Where am I missing the point?
Cheers
Make sure you AF-ON and shutter buttons are set to AF.

problem with 7d mark2
Set up app with target on my laptop. Using galaxy s3 and android 4.4.2 the app crashed before completion due to a communication error and the camera locked requiring a battery pull. The message on the camera display was err 80.
Not really sure what is going on, but I've been having issues with the 7DII as well. This is a very low priority project for me though, so I have no idea when I'll get around to fixing it.
7D Mk2 with Galaxy S5 under lollipop.
App starts, DSLR switches to remote controled mode, The appdoesn't recognise spot metering, I switch to center. Then the app show the mandaoty dialog but "Start AFMA test" stays gray.
Same problem if starting with center metering (appart that the app doesn(t complain about it anymore).
Is there any debug log or test I can do ?
I have the full paid DSLR controller if that is any help. I quickly tried to shoot a few test shots with DSLR controller and it works.
Cool app. It works with my Verizon LG G2 and 7D (mark 1).
Where can I download the targets to display on a computer screen? My phone's screen is too small to be a target at 30 feet.
I too have the DSLR Controller app and it is pretty fun as well.
overclockxp, you can connect to the URL displayed by AFMA on you G2 from you computer. The web-page will display the necessary target.

Did you have to do anything special to get it to work with the 7D? I can connect to standard DSLR Controller just fine on a Droid Maxx and a nexus 7 but AFMA refuses to recognize the camera.
EOS 5D Mk3 / HTC One M9
I have DSLR Controller working between these two devices (1) over a Lindy USB OTG cable and (2) over Wifi using a flashed MR3040. But the AFMA app does not find the camera over either connection method (not sure whether it is supposed to work over Wifi anyway). Am I missing something or should the AFMA app also work when using exactly the same connection cable and camera setup as the main DLSR Controller app does ?
Seems Good > ThankZ
Feature request / suggestion
Hi again. (Got this App working over Wifi finally but still not when using a direct connection, although the main DSLR Controller still runs fine both ways - see my earlier post; any reasons why AFMA might not work on the same cables as the main App does ?)
That aside, when testing zoom lenses it would be useful to have the focal length set for each test recorded into the saved report. (This data is recorded into the EXIF for images, so is presumably available in camera to the App but it isn't currently reported.) I've just run pairs of 4x tests on each end of 3 different zoom lens and so have 12 reports to collate. Differentiating between the various lenses' reports is easy with the report titles but the different focal lengths' reports can easily get confused for a given lens.
Hi, there!
v0.12 + canon 7dm2 fw1.1.0 + galaxy s5
it is hard to connect, it search for device, but it do not connects.
only 1 from like 20 attempts. I managed to really conect (get "online") just 3 times at all...
Then, after starting AFMA it focus, then defocus, then calculate and suddenly camera get Err 80 and that´s it.
Any help, please?
EDIT: The same setup but with Lenovo k920 = Communication Error on the phone, Err 80 on camera.
I do not believe it is working at all.
Unfortunately.
I am a member of a small student team which is trying to emulate camera from virtual Android machine into Windows 8. We've made a little research and haven't found any camera specifications or protocol. First of all we want to replace video stream from camera into ours. We found that we can't capture video stream changing some functions in android.hardware.Camera (maybe we are wrong?). Also we haven't found this class on HTC One (because we have to replace it).
Therefore we have many question and nobody to ask. So I'd like to say about things that I haven't known completely. Please correct (if it is necessary) and help me in this issues:
How many different camera protocols exist?
How does they look like?
What is the difference?
(As I can understand all laptop cameras work using usb protocol, so do usb cameras. But how does camera work on HTC One on hardware level?)
How can we capture and change video stream from camera on Android except going inside the kernel and can we do such thing?
Thank you for your attention.
P.S Also you should know, that we are just beginners and we may have wrong ideas
Hopefully there's a simple answer to this, and hopefully this is a place to find it!
I'd like to be able to switch between the front, back, and a USB-C connected camera for input to streaming apps (notably Facebook Live, and Zoom conferencing, but would like a more general solution). Ideally, video mixing (e.g., picture-in-picture), would be nice.. The primary application is to stream live interviews, site walkarounds, etc., from a gopro or the camera in a pair of AR goggles. E.g., live stream the view from the head-mounted camera, with an inset view of me, from the phone's front camera.
Right now:
- I can almost do it all from a Microsoft Surface - the basic camera app allows selection from front, back, external USB camera. Control of camera selection is through the system settings dialog.
- On a Samsung Galaxy Note 20, I can't seem to find the equivalent of a system-level setting. The basic camera app allows for picture-in-picture still & video from the front/back cameras - but doesn't seem to have a way to select an external camera. Facebook live allows switching front/back, doesn't seem to do picture-in-picture.
Documentation for all this stuff seems hard to find. I've been pouring through the various android developer sites, and device related sites - lots of stuff on low level code interfaces, nothing on what's actually coming across the cables, and mostly out-of-date youtube videos on how to do very specific things with very specific external video switches, and various downloadable apps that don't seem to work very well.
Which leads to the following questions:
- Are there any deeply buried settings - in Android, Samsung Developer Tools, or Facebook, Zoom, Teams - that let one select a usb camera? (Bonus for allowing picture-in-picture.)
- Any recommendations for an Android video switch/mix application that inserts itself between the system video interface, and standard apps?
Hopefully, amongst all the noise, there's a simple solution.
Thanks very much for any assistance anybody can offer.
