[Q] Nexus 7(2012) Webcam OTG Issue - Nexus 7 Q&A, Help & Troubleshooting

Hi, i am looking to use webcam(s) with my Nexus7 to run AR navigation apps like Navigate 6 or iOnRoad however have been unsuccessful in getting the webcam to work with Nexus 7 in this form
I am running Timur's USB ROM - apps like simplewebcam run absolutely fine and project the webcam images through the N7 however when i attempt to use the native camera thru this http://forum.xda-developers.com/show...2100452&page=4 method. The native camera app closes with "unfortunately, gallery has stopped"every single time. i also attempted to browse through similar threads but haven't been successful. I have already tried restoring to factory settings, switched ROMs (including Stock) and yet no avail.
I want to eliminate the need of using 2 different apps for dashcam and navigation hence this requirement (desperation). I am a complete n00b however have one medal to my credit : was able to get a powermate to work with the N7
Any help would be greatly appreciated

[Q] Advent Vega Screen Capture App

Hi
I'm having trouble with Android screen capture apps on the Vega - all I get is a blank image. I've rooted using z4root before hand and have tried 3 or 4 different free screengrab apps.
Was wondering if anyone had a similar experience or could recommend an app?
Cheers
All the apps I've tried give a blank image as well. I guess we only have the possibility of using the SDK...
Suspected as much, thanks Logseman
There isn't anything you can run on the device at the moment, however, if you don't want to delve into the SDK, you can use DroidExplorer (Google it) and that allows for screen capture and even remote control..

I need to know HDMI basics o_O *confused*

Hello all... I'm confused by the HDMI capabilities of my Evo. I'm under the impression that when you connect the micro HDMI cable (I just bought), you're able to view your phone's screen on your TV--as thought it were a large monitor. I thought this is what "mirroring" meant.
All I can see with this micrHDMI cable are videos, slideshows and photos--all pointless activities to the way I use my phone, oh! and play a video game or two, which I don't do. I installed two HDMI apps--the only two that I found on the market. The only thing I have not done is flash a different kernel.
Before I flash another kernel, do I have the wrong idea about what mirroring means?

No, you don't have the wrong idea. The evo's native HDMI capabilities will only allow you to see certain things on the tv screen, such as youtube, streaming video, the gallery app, etc (as you already noted). There are two apps in the market, both of which I've had success with. Those apps (fullhdmi and hdmwin) both allow you to mirror whatever is on your evo's screen to the tv. Anything on your phone's screen will be mirrored to the tv you have it connected to. I havent used either of the two apps in a month or so actually, but I thought that a custom kernel was no longer required to use either one of them? (although a custom kernel did make things seem a bit smoother, as I believe it enabled hardware acceleration)
So in short, you don't have the wrong idea, and you are indeed able to do what you have set out to do.
EDIT: I just noticed that you said you have intalled both of the hdmi apps on to your phone. I would suggest uninstalling one of them, as they could interfere with eachother. Decide which one you want to use, and then uninstall the other one and reboot your phone, then try it.

As always, k2buckley is on point. Please note that for the best results, a custom kernel (check my sig for the one I'm using) is better because it will allow the app to work better by allowing certain features and output resolutions to work that will not work without the custom kernel. I use the mirroring feature frequently, so for me it is worth having the custom kernel.

Thank you for your prompt response. Could the problem also be in my TV settings?
This is what I did (Using a 52" Panasonic plasma - w/Vieracast):
1) Installed the app. (Full HDMI by Team Win, uninstalled. Installed FuLLHDMI by orrebmas)
2) plugged everything in (HDMI to HDMI1 port on my tv and micro to the Evo)
3) Selected the input to HDMI1 (using my remote).
4) Results, *Black screen* I didn't see anything until I produced the Gallery, YouTube or videos on my phone which now I'm learning are default.
Other than flashing a custom kernel, I can't imagine what else you'd need to do.

Did you open up the FullHDMI app, and click the button that says 'apply and start mirroring' or something to that nature? It doesn't sound like you started the actual app. And if you don't start the app, it reverts to the phone's default capabilitites. Once you start the app, and hit the button that says start mirroring, it should start. If it won't display, you may need to change the output resolution. I believe there were 4 or 5 settings in the app. On my TV, which is a 50" Samsung, only 2 of the settings would work. All of the other settings, my tv would say something like 'format not supported'. I had to mess around for a couple minutes, but was able to get it to work. And it worked rather nicely as well, once I got it going.
You can find trouble shooting tips and even live support via chat on the FullHDMI website here:
http://members.cox.net/lokifish/index.html
As buckley said, once you connect the HDMI cable from your phone to the TV, you need to hit the button that says "Start FullHDMI Service". If you get a black screen, hit the second tab and make sure the resolution is not set to 720p (unless you have the custom kernel). Also, please note that 800x600 is a resolution for computers and not supported by all TV's, so you may want to try PAL or EDTV if you get a black screen. Once you change the resolution, go back to the main tab and hit the start button again. Since it is already running, it will say "Reapply Service" or something like that.
There are many more trouble shooting tips on the site asides from what I mentioned above. I suggest you check it out. Lokifish is pretty good about being on the chat server, so chances are you can get live help there, as well.
Ok, there we go... it's working. The setting my TV will let me use is EDTV. Thanks everyone for all your help.
Now back to stock YouTube
will not work. I have tried disabling HDMwin service already without success.
Also tried uninstalling stock onboard YouTube and re-installing it.
If I disable HDMWin service, shouldn't this be all I need to do in order
to use onboard YouTube without mirroring it?

If you're on a Sense rom, the YouTube app should work with the native HDMI capabilities of the Evo. If you're on an AOSP rom, you will have no native HDMI capabilities, and the only way for HDMI to work is with one of the two available apps in the market. If you are on a sense rom, and it's still not working, there could be a few things causing your problem. Such as a bad HDMI cable, a bad HDMI port, or the particular kernel you're on may not support HDMI output.
On on a Sense ROM
Netarchy.
The native HDMI worked prior to flashing Netarchy so I know it's ok.
One thing kind of odd that I noticed with the native YouTube before I
re-installed it. The search function stopped working for some reason.
I have no idea why. So, I uninstalled the native YouTube, re-installed
a new one and the search function is back. I now also have two YouTube
icons, only one of which works.
I have yet to try the new native YouTube for HDMI and will do that today.
I also tried dragging the "old" Youtbube icon off the desktop but it won't
disappear.

[Q] CM9 can't connect to DLNA/UPnP server

I am so stoked with the current state of CM9 ICS with the exception that I can no longer stream video from my DLNA/UPnP server. The problem is that I end up in a never ending search for servers. I have tried re-booting, toggling wifi, re-installing and while it works with CM7, I can't get it to work in CM.
I have searched high and low on xda and Google and found one fantastic user (jdommer) who seems to have solved the issue on the Kindle Fire. Any chance of bringing this fix to the Nook Color builds?
http://forum.xda-developers.com/showpost.php?p=23696294&postcount=2497
What app are you using? Or are you just doing the file manager/open with routine? View your files with a file manager and click a file to open with a media player?
Would you consider dual booting? I do and it's easy as pie.
Thanks for the reply. I have considered dual-booting but prefer CM9 for everything except this one failing.
With CM7 I used (and have attempted to use in CM9) BubbleUPnP or MediaHouse to brows networked media servers and initiate a stream which is opened in MoboPlayer or the like. The issue is that when opening one of the aforementioned UPnP network browsers, no servers are found and scanning takes an extraordinarily long time to complete.
As I said in my first post, this issue has been solved for the Kindle Fire so I'm hoping the fix could be incorporated into the nightly CM9 builds going forth.
So are we thinking this is essentially an issue with multicast not working properly, or... ?
I've been having problems, too... aVia, MediaHouse UPnP / DLNA Browser, neither one sees my Gentoo/MiniDLNA server. Logitech revue sees it fine, as does aVia on the TBolt. When I install any of those apps on the Nook, it causes some serious issues with network access. Maybe I'm just not being patient and giving it enough time to discover the server, but with both the Bolt and the Revue it was instantaneous.
I'm not allowed to post in the developer thread, so I hope a developer in reading this. The issue still persists in nightly 9/4/2012.

[Q] USB webcam as default

Hi guys
I recently found out how easy it is to connect your USB webcam to the Nexus 7 & use it as a camera using the Simplewebcam or DashCam applications.
Now I would prefer to use one of the feature-heavy dashboard camera applications in the playstore, however these always use the internal camera.
So my basic question is: is there any way to trick the Nexus into thinking the USB webcam is actually the built-in camera?
Thanks in advance!

Element E4STA5517 55" 4K Android TV [TU43GDX] upgrade os?

Hi all, wondering if anyone has attempted messing with this unit - found nothing on Google/duckduckgo.
Had it 2ish years, been a glitchy little monster and apps like Hulu show incompatibility (though they are 'preloaded' and on the menu). So far as I can tell the system OS has never been updated and am curious what might be done to refresh it?

Unfortunately most android TV's don't get updates because the manufacturer doesn't take the time or resources to make an update and push it to the TV's.
As for glitches and apps I would try expanding it's memory using a flash drive and moving apps to it and letting the device use it as internal storage. And I'd use a PC or laptop and download the free program called "adb app control" and use the debloat option and clean some stuff off it. I'd also suggest getting a lighter launcher than the default one. There's a few options here -> Link but I like one called dashboard from the playstore. Also install a launcher manager and/or button mapper (both are free). Hopefully some or all of this helps make your tv a little snappier. I have a fairly new Hisense android tv and I did all this and it feels a lot better than stock.
