I'm well behind the curve on Android in the car and I'm not sure this is even the right place for it but I have a concept for a system and I'm not sure whether the current state of the art permits it. But here goes anyway.
The car is exotic and rare: a Renault Avantime. Here's the cockpit:

You'll note that it's a work of art (may not be to your taste but it's one of those rare beasts; a concept show car that actually went into production). So I don't want to mess with it too much. You'll also note that there's a bump with a Satnav screen (factory system: old VDO/Dayton thing) on top of the dash. There's also a large flap cover forward of the gearshift; that covers a double-DIN hole which was used for the factory CD and satnav controls panel. The factory radio is a headless unit under the seat which runs a dashboard display and steering wheel controls - with a remote for more complex functions.
What I want to install is an Android system with multiple inputs and outputs. The primary display would take the place of the flap forward of the gearshift. The brains of the thing may or may not be integrated into that display.
Inputs would consist of:
- a cabin webcam used for Skype etc.
- a backup camera (no factory fit)
- a forward-looking thermal camera for night vision
The primary touchscreen display would be in front of the gearshift as described. The existing Satnav display would be adapted for a secondary screen (probably not a touchscreen; just a display): normally it would show Google Maps - or some other app for nav data. But it would be selectable via software to display the backup camera view, the thermal camera view, or the Skype display when in a Skype video call.
Obviously the unit would need to be capable of controlling and driving an external AM/FM receiver/amp for that side of the entertainment functionality.
Is any Android system capable of handling these multiple inputs and outputs? The ability to display specific apps on the secondary display is kinda crucial to what I want to do here; are there any general solutions to getting multiple video streams into and out of an Android device? Or would I be better considering a bespoke car PC based on Linux or something? Any suggestions gratefully received.

This tool is the first spectrum analyzer tool for Windows Phone 7 available. Capturing ambient noises and sounds using your phone's microphone, it processes it in various ways and visualizes its results.
Features:
- 512-point FFT with a frequency range of 8Khz (current XNA limit)
- Several windowing functions for the FFT
- Displaying of the prominent frequency in note pitch
- FFT zooms down to 2Khz
- Sound pressure level metering using Linear/Z-, A- and C-curves
- SPL floor can be raised up to 100dB
- Peak and RMS metering of raw captured microphone input.
- Peak/RMS floors can be raised up to -24dB
- Waveform display of normalized input.
Note:
- Due to different manufacturers and internal microphone preprocessing, your results may vary. The SPL metering allows you to calibrate the results +/-30dB.
Cost: 1bux!

nice app
Very nice! Please give landscape support in furture release...thanks
looks pretty nice, i'll find a use for this .
Anyone who's going to buy this:
Smartphones have crappy miniature microphones. They have a considerable noise floor, so if you're in a "silent" room, the meters WILL display something. They will anyway, since a room is never entirely silent, alone due to the brownian movements of the air that'd even make a high-end mike pick up noise.
SPL measurements are based on a logarithmic function. The sound pressure difference between a faint sound and a little lesser faint sound is way larger than between a jackhammer and a jet engine. That's the nature of logarithms. Here, take a look at the log10 of the values from 0 to 10000:

}
Note how the difference from 0 to 1000 is way larger than from 5000 to 10000.
In essence, the application's not broken. The theory behind it is sound, it just has to make do with what it can work, namely a noisy microphone.
Is there a free version of this app?
Thanks
thx tom but why it s free on your site and 0.99 on zune market ?
Ah, the site is outdated. I kinda had to change my mind, when that supposed "five free apps" suddenly changed to "five free submissions for free apps". Means, after the fifth submission of a free application or an update of one, I'll have to pay 20 bucks for each free submission. So I have to charge something, especially since I refuse to put ads in my applications (e.g. to pay for update submissions). I figure I could put a trial mode in, but I'm not entirely sure how I could cap the application, nor whether a unlimited-time fully functionality trial applications will pass certification (since it defies trial mode and affects their income).
Bamp! 10 chars!
Hey Folks - I could use some help here I am stumped.
I am working on a project to launch one of my model rockets and stream the launch video live via USTREAM (using an LG Revolution modified to be onboard). The issue is USTREAM sets the camera to landscape mode so the phone needs to be held in the landscape position for the video feed to be oriented properly for viewing. The problem is I need the phone to be oriented in the PORTRAIT position due to size limitations of the rocket itself.
USTREAM does not offer the ability to rotate the video stream.... so I was wondering if anyone (dev?) can write a middleware app that will force the camera output to be rotated 90 degrees before the application layer receives the stream? Is that even possible?

FYI: I have tried rotating the camera physically but the connector ribbon is too short and doesn't afford the flexibility for such a move. Creating an "extension" cable is also not in cards since the plugs are nano-sized surface mount.
Thanks in advance...
I have no idea how to do that but please let us know about the launch. Awesome project!
This really does not belong in Development so I have gone ahead and moved it. The project does sounds interesting and I wish you good luck.
Android1 Project Thread ...
Launched the rocket and As-droid-naut this past weekend (minus the LG) - here is the thread I started in the General area if you want to see what I'm up to:
http://forum.xda-developers.com/showthread.php?t=1892422
Dashcam
Did you find a solution?
I have tested a lot of dashcam-apps (f.i. 640x480) and the phone in mounted in portrait, the video is only in portrait (480x640). On the pc i have to transform it 90 degrees.
Camera gets its positioning from the accelerometer. Need to somehow fool the camera into thinking it is vertical all the time.
Thanks for the quick response.
That is not the problem. (It is easy, to rotate the video later (and maybe crop) on the pc.
My phone camera has 8 MP CMOS (Landscape 3264x2448 or Portrait 2448x3264)
I need only the upper 720x480 (or better of the 2448x3264) and not 480x720.
The lower part of the video is waste. (only the dashboard, what is not very interesting)
(If I rotate my phone 90°, i see only the dashboard and a little bit of heaven, but no street.)
A higher mounting of the phone holder is not possible.
The best solution is a dashcam-app with a possibility of selecting a video area. Why is it so difficult to program?
Is there a way to force the chromecast to display what is on the screen as rotated. I have a tv that is turned vertically and I want my vertical devices display to take up the whole screen.
If you stretched the image everyone would look like aliens...what I'm saying is it would massively distort the image.
Well thats good to know?!? So bavk to the question at hand... can the mirroring be forced to be displayed in a rotated state? Heres an example of my tvs orientation...

No because the TV would have to do the rotating....
No matter how you turn the TV the TV still considers the TOP to be the TOP!
CCast has no ability to change that or re rotate its output on it's own....
The only way I can think of to do what you propose would be the use of an expensive device that can take any input and rotate it before it gets into the TV.
And those would cost in the thousands.
Do you have an example or a link to such a device?

I work in digital signage and we have 1,000s of screens which work like this. And software and hardware which deals with it. Its all commercial grade though, which the Chromecast isn't.
I'm sure technically the CC *could* do it, but I don't think google would spend time enabling it to be honest. So without rewriting a large chunk of the firmware, then no you can't.

You could perhaps code a custom app and CCast Receiver that could allow you to rotate video to the proper orientation.
The Difficulty would be in how you would go about doing that...
Two Methods I can think of are:
1 - rotate the video during transcode before sending it to the receiver app. (key issue will be power of a mobile unit to Transcode the Video)
2 - Create a receiver app that can rotate it's input on the fly. (probably difficult to pull off due to sandbox and memory limitations of the CCast)
The device I linked to above might very well work with a CCast since it has an HDMI input. But you may have to trick the device into multi Monitor upscaling mode to get the right effect.
I don't have any experience with the quicks or cheats on that device so be sure to give it a test run to ensure it meets your needs before you buy!

Hey there guys, I'm writing in the off topic section about this e-cigarette I've just got, it's called Joyetech Ocular C and it comes with a color touch screen , music player and photo viewer capabilities , bluetooth conectivity, a pedometer to count your steps and from what I understand, it has around 2Gb of memory , it is firmware upgradeable and I'm wondering if there is more that can be done to it in therms of functionality.
It's true that vapers, the people who smoke e-cigarettes as their called, dont really need any of this functionality in their devices since they mainly use them purely for smoking, it's nice however to have something a little extra to go with it.
I've looked online for custom firmwares or methods to customise your firmware for these type of devices, but i've only found info on old devices that come with small monochrome screens and the most you can do is upload logos on to the device.
My interests are on how you can access the root of the system built into these devices since it must have a processor and a file sistem inside, how to edit some of these files , per example, you have the option to upload around 100 pictures and some songs ( the memory on it is 2GB ) but there's no way of deleting them once uploaded, in case your storage gets full.
Also it would be nice if users could implement or extent more functionality in the device, par example it only suports .jpeg files in the photo viewer , .png &/or .gif to use as a screen saver would be nice, more so even video playback capability .
And before I get laffed at for asking so much out of an electronic cigarette, I think that since it does come from the factory with all these functionalities and hardware, it's a shame they dont use it to it's fullest.
So is there anyone having any clues on how to "get inside" these devices and tuning them up ?
I've included the latest firmware I could find for the device as well as the program they offer for you to upload it onto the device. If anybody could crack it opn and take a look inside and see at least what's in there, that would be a start.
I know it's been discussed before, but according to the N9600 variant getting root recently, the dev @Mentalmuso made up my mind with his WETA thread unsurprisingly the .apk I've been looking for was there but obviously it's unable to install for being a system thing which makes me wonder:
Since the system partition is untouchable without root (which is not in sight) and this apk has to be placed there to work, flashing it somehow is the only option I suppose.
Just for the clarification - I don't like the Next radio experience at all and I'll name the reasons from top to bottom:
1. No record button - this is the most critical for me. The Recforge workaround which I counted on no longer works here.
2. No RDS. There is a built in database that gathers up information on your current location and names the frequencies to the stations in this area. For people outside U.S.A this feature is useless.
3. No swipe for fast navigation across the dial. Inconvenient manual frequency typing forces me to empty the field then type in the desired value, must insert a "."dot for decimal separation.
4. Only odd numbers are displayed. It may as well pick up the even ones properly (since 2016 it should) but still display them as odds.
5. On screen advertisements - I wish to use a service that is already commercial, why do I need such obstacles in the way?
6. Load times - though quite minor flaw but Next radio has a splash screen for at least 2~3 seconds then it takes a few more seconds from the moment you push the operate button until you can hear a sound, compared to the stock operation which takes almost instantly. Also the seek buttons have a small delay in Next radio.
Again, only the miss of record is really bugging me to the point I consider a switch to N9600. If Recforge did it for me (or a sound recorder equivalent) I could live with the rest. Apart from this I'm completely fine unrooted.
Any idea of how to legit flash this .apk or a new way to record that doesn't involve aux and streaming?
