easycap not working

I just got my easycap and cam but cant get it working. I popped open the case and its a somagic chip. From what I understand this should be working.

Ive plugged it into my usb hub as well and directly into my otg. No matter what app I try it wont detect the cam. Suggestions?
[Nexus 7 Android Development] besjr69:
I see there's been a lot of traffic regarding the EasyCap. I must have ordered three of them with the wrong chipset. Finally I just settled down and ordered the FEBON100. This device is sold in China, but works RIGHT OUT OF THE BOX with no modifications or adb commands. Look it up. The seller is very responsive and FAST (< a week from China). Try it out. It will save you a lot of headache.

Get the newest build.....has cool volume buttons....and functioning correctly.
[Nexus 7 Android Development] gregthomas129:
Sorry, didn't realize I'd downloaded the wrong build. Carry on!

---------- Post added at 12:06 AM ---------- Previous post was at 12:01 AM ----------

Hmmm, I believe I have the latest build.... The name of it is: Slim-grouper-4.4.4.build.6.3-UNOFFICIAL-20140716.zip

I downloaded it from zippy share, and I see there's one from devhost too, is it possible the one in the zippyshare link is an older build?
[Nexus 7 Android Development] michiil:
Oh damm thanks for telling me.. Yes devhost is the newest one.

I will upload the newest one to zippyshare when i get home (:

EDIT: Now the links work (: i postet the newest build in the spoiler. My bad..

Peace
[Nexus 7 Android Development] gregthomas129:
No problem, I'm almost finished downloading the devhost file anyway. [emoji6]
[Nexus 7 Android Development] michiil:
It its the 20140716 build the the wrong one to..

Sry.. The right one is 20140719.
[Nexus 7 Android Development] Iceman_jkh:
Can't wait to install this.

Thanks Michiil and redeye!
[Nexus 7 Android Development] michiil:
You dont need to wait (:
[Nexus 7 Android Development] gregthomas129:
The new release is almost perfect! The customizable navbar is exactly what i wanted for my in dash setup. Does easycap work with this?
[Nexus 7 Android Development] michiil:
The navbar was the mainreason i built this rom (:

Easycap support is planned (:

Are the media keys fia tasker?

I plann to implement media keys in the next built because on tasker there always is a delay ..

Peace
[Nexus 7 Android Development] michiil:
Uploading new build.

Changelog as always in second post (:

Peace
[Nexus 7 Android Development] RoNeReR:
i decied not to wait for 3g and to install grouper recovery and after that this rom...

so first... tnx for the great rom..

after one day with this great rom in my car i have some quastions

1. there any chance to get landscape boot animation?

2. add performence setting to set other govrement

3. add pic to power loss screen ( in timur rom u put pic in internal storage)

4. after my tablet wake up the volume its half volume and one press of volume up change the volume to max.
[Nexus 7 Android Development] michiil:
1. Yup but i dont know yet whitch was i should take but i think i go with the slim one just in landscape.

2. I wont do that because i think its not worth the effort since you can simply download trickster mod.

3. You have to add a pic named powerdown.png to /data/data/org.kangaroo.pem/ and tada (:

EDIT: You need to change the permissions of the powerdown.png to -r--r--r--

4. just treid that and couldnt reproduce.. are you using poweramp? then you have to set /settings/audio/advanced setiings/direct volume to off

peace

EDIT: i have a tilapia build ready now could someone try it out for me before i post it? pm me

Bluetooth crashing

Nexus 7 (2012) wifi. Loaded up Slim Kat, everything seems to be working fine, except for bluetooth, which crashes immediately on boot. any ideas?

:confused:
[Nexus 7 Android Development] michiil:
What build are you running? I dont have any problems with bluetooth..

Did you do a clean flash?

Peace
[Nexus 7 Android Development] bigdogbts:
Flashed the most recent build (Slim-grouper-4.4.4.build.6.6-UNOFFICIAL-20140723). Did a full wipe from TWRP before installing. Pretty standard ROM installation. Wish i had more to give, but the "bluetooth share" crashed so repeatedly that i had to revert to stock just to get functionality back.
[Nexus 7 Android Development] michiil:
Wierd.. As i said i cant reproduce it..

Maby try different gapps or something?
[Nexus 7 Android Development] bigdogbts:
I'm running through the install again to see if maybe i missed something. I'll keep you posted.

---------- Post added at 03:30 PM ---------- Previous post was at 03:24 PM ----------

Yup, i missed something. Second time through, everything works perfectly. Thanks.
[Nexus 7 Android Development] redeyedjedi:
It will soon.....I've got to tweak some permissions.

Need to see if I have contributor status.
[Nexus 7 Android Development] michiil:
What repos do you need for the easycap support?

Tilapia version is up now link added in the op (:

[Nexus 7 Android Development] dashu42332:
I am using this ROM from 4-5 days. The problem I am facing is USB Disk (Pen drive) take 3-4mins to get recognize in the Apollo player and also Google player. And if mp3 is playing from the USB disk, when tab wakes up it doesn’t start play automatically.

Other thing battery charging is slow, when music or navigating on tab. sometime it drop from initial charge.

My setup is Nexus 7(Grouper)

Easy cap UTV-007

UCA222

8 Flash (USB Disk)

Power supply 5vdc 3.4A

If any Tasker task need to be programmed for solving the above problem. Any suggestions are welcomed

Thank you all for their work to make such wonderful ROM:good::good::laugh:.

Waking from sleep

This rom and have to say its great..

The only the issue i'm having is when I use Power Event Manager to put the tablet to sleep.. Sometimes it will not wake when power is connect once I turn on my car.. tasker just will not run the profile on the tablet is in sleep for more then 5min or so.. its like it did not see the even of the power being connect when it is. what are you guys doing to wake your tablets in your cars when power is connected
[Nexus 7 Android Development] machmanx:
Well because the audio device switches from the internal to the UCA222 you cannot get it to autoplay when you turn the ignition to the ON position. The system pauses the music to allow the switchover between audio devices. What kind of power supply are you using anyway? Like some cigarette lighter adapter with two ports? If so then it might not be so easy to get full power out of that port because there is a trick that activates the full charge...at least what I think. Google to see if this is the case. Otherwise the other option is to use a multimeter and set it to amp mode and then connect it to power to see how much amps are actually flowing to the device. If it's 500mA or around that area then it's what I said above since USB by default charges at 500mA. Also google to see how to hook up an ammeter or multimeter for amp measurement. Then again if you already know how to use a meter then excuse my rudeness and I would recommend loading your power supply separately to see if it truly can produce the 3.4A it advertises or at least more than 1A.

How do you have your power hooked up and what is your setup? Need more info...
[Nexus 7 Android Development] TriC_101:
Have usb hookup... with shorted data pins so it sees it as an AC connection..

Also could someone post their Tasker profile... so I could see what's different from mine when it comes to waking the nexus7?
[Nexus 7 Android Development] papinist:
For me audio resume works perfectly. I'm using Poweramp, but works with Apollo too an even with Spotify :) I'm not doing anything strange, but when switching off the car, music pauses, and when start the car music resumes (after powereventmanager got superuser permission).
[Nexus 7 Android Development] 1xinfusion:
I solved it by wiping, and then flashing the latest superuser.zip from the internet and then rebooting into recovery. It seemed recovery did not have superuser rights.. which is weird

---------- Post added at 05:31 PM ---------- Previous post was at 05:30 PM ----------

I've noticed with this rom, it does not wipe system. at least on f2fs. So to install this rom you must wipe system, cache and data. Then install the rom & gapps right away without rebooting. If you reboot after wiping system without flashing rom, the recovery will throw symlink errors which is only fixable by flashing a superuser.zip. Reflashing recovery does nothing
[Nexus 7 Android Development] machmanx:
That's why

Yeah that's why. The way this ROM is setup it has to detect charging while in OTG mode <--That's the key. So you can't do it without the OTG cable. There are other implementations out there (that I heard of) that allows you to make the tablet sleep and wake from simply detecting AC power. But yeah, in this ROM, OTG is a must for that functionality. This ROM is more than just a simple "turn on and off" system...it has a lot more features.

Really? Wow it never works on mine like that. Not that I care anyway and prefer hitting the play button to play my music. Is this some kind of setting in Power Event Manager? Oh, are you even using a DAC?
[Nexus 7 Android Development] papinist:
I know, even with USBROM I had resume play works and other users don't! Yes I'm using a Behringer UCA202 and no special config in pem or anything.. I need to do a video of my install sometime :)
[Nexus 7 Android Development] Walz83:
I managed to get my hands on a EasyCap with STK1160 chip and it works great with carcam.

I noticed that when I disconnect power to the usb hub, the value of X of the VideoX file changes, so I have to change the X value in carcam settings.

So i am thinking in order to avoid this when i eventually install in the car, I should have the usb powered from a constant 12V source rather than 12V on ignition source (e.g. cigarette lighter)? Is that the right way to do it?

Can anyone with a working setup confirm how they got around this?
[Nexus 7 Android Development] dashu42332:
As mentioned in reply I try test amp consumption by all device including the table. And result was 780mA to 560mA. Then I tested only with table and give me result 260mA to 300mA.

Now I have wired all the salve device separately from the table. And now the table is withdrawing around 520mA (and getting charged).But still sometime I notice in the table especially when charge is below 20% the charge is slow (when all wifi and gps is on).

And you’re right I am using cigarette lighter adapter with two ports.

And regarding audio. If I store the music in the table, then the music will pause and resume according to ignition. Only if the music is present in flash driver (USB Disk), it will pause when ignition is in off. But doesn’t resume when ignition is in ON. Because the flash driver data or music takes around 2mins to load in Apollo player. After couple try to load and close music app the all music from the flash driver appears and need manually select play. Is there anyway after music get recognized in music player automatically play without any manual input.

Thank you very much for reply :good:
[Nexus 7 Android Development] jeepwoody:
I just ordered everything, and I swapped out the above that you mentioned here. How did you power the USB hub? Or are you just running with an inverter? The only thing I can think is to wire in a 12v to 5v step down directly into the supplied DC connector (i.e. http://www.amazon.com/Kimdrox-Waterproof-Converter-8-22v-Supply/dp/B00LHZ6H1S/ref=sr_1_39?s=electronics&ie=UTF8&qid=1414983171&sr=1-39&keywords=12v+5v+2.5a+step+down ) thanks man
[Nexus 7 Android Development] papinist:
Have you set a powerdown video in powereventmanager? When I have this easycap device connected it works but at powerdown I always get an error playing that video. I haven't found how to disable that video, too.

For your issue, I haven't checked if 'X' of videoX changes, but it works even after powerdown and resume so I assume it don't change it.
[Nexus 7 Android Development] machmanx:
As I said + 12V to 5V

So I think it's exactly happening as I said...your cigarette lighter adapter requires some kind of trick to activate the higher current flow. Most likely one plug is meant for iPads and iPhones and like I said, if you had googled you would've figured out the trick behind how to enable that higher current output, otherwise it defaults to 500mA +- 10% tolerance. I think it's a resistor that is shorted on the data terminals, I'm not exactly sure about that. The Android port does a simple data pin short that gives out 1A.

You can use the same cigarette lighter adapter to charge the tablet and power the hub. As long as you keep the positive wires on the plus side and negative wires on the minus side you can hook up multiple devices on the 5V output side of the cigarette lighter adapter. That's the beauty of current: It only gives out what is asked for. I used a 12V to 5V buck converter instead of a cigarette lighter adapter for my entire setup, but most people seem to prefer the latter.
[Nexus 7 Android Development] Walz83:
I have set a powerdown video and all works fine.

If you want to disable powerdown video/image it is in powereventmanager: set 'Skip countdown screen' to ON.

---------- Post added at 02:04 PM ---------- Previous post was at 01:13 PM ----------

Has anyone managed to get a DVB-T tuner working ?

If yes, please provide details: type of tuner/chips, apps used, etc.
[Nexus 7 Android Development] papinist:
Thanks for the info.. but I don't want to skip the countdown screen, only remove the video playing. Before I set a powerdown video, there is the countdown screen, but after set that video the countdown screen does not show up anymore, only the video. So I want to try to remove only the video and have the countdown show up again.

I have bought another Easycap (only 6 eur at a local faire) so I will try if with this it will work correctly.
[Nexus 7 Android Development] Walz83:
Why not just set an image instead of a video?
[Nexus 7 Android Development] papinist:
I haven't think of that.. I'll try thanks!

Power Event Manager Issues

Let me start off by saying... this ROM is great!!! Thanks so Much..

adding final touches to setup before mounting fixed in dash. all this said I'm wondering if anyone is experiencing inconsistency with Power Event Manager at times does not power down and firm sleep the unit...

current setup

OTG cable, no external devices connected.

AC power 2Amps

DC power 2.1 amps

It came to a point where only way to engage is manual powerdown by hitting the power button the PowerEvent Manager app.

is it possible something is wrong with my OTG cable?

any insight would be greatly appreciated

thanks again for this Rom and community assistance..

HELP with DVB-T . Please...

Has anyone managed to get a DVB-T stick working?

I figured what I need to do first is insmod the dvb modules.

I have a rtl2832u based stick so i think I have to insmod these modules: dvb-core.ko, dvb-pll.ko, rc-core.ko, dvb-usb.ko, dvb-usb-rtl2832u.ko

I managed to insmod all of them except for dvb-core.ko, I get error: insmod: init_module 'dvb-core.ko' failed (Exec format error).

Can anyone help please?? this is the last bit i need to sort out before i finally install in the car.

Rear view cam

Hi,

Tried to search the thread but didnt really find the answer, but does this ROM still rely on Carcam as the app to show the video feed from the Easycap, or did someone actually write a new app?

Love the work on this ROM, as I loved the Kangorom before it. This is going in the car, if I can just get the shaky Carcam to actually work after a deep sleep as well...
[Nexus 7 Android Development] Walz83:
I haven't seen anything out there other than Carcam.

Carcam works fine for me, I'm using version 1.4bbb. try that version if you are on version 1.3.

Guys,

To provide internet access, rather than using my phone as a wifi hotspot i am thinking of using a 4g wifi modem or usb dongle.

Would a usb dongle work by just connecting via usb in host mode?

What are your thoughts on usb dongle vs wifi modem?
[Nexus 7 Android Development] 1dirtypanda:
Hi,

I had USB-ROM installed but wanted to try out AutoDroid.. The instructions on the install isn't working for me. I have TWRP 2.8.1.0 installed and know how to convert to FSF2 via Advanced Wipe. If I follow the instructions exactly on the very first post under "How to convert to ALL-F2FS:" my N7 get stuck and don't boot past the Google logo ( I have tried on both grouper and tilapia).

I then found some post where they installed a F2FS version of SlimKat first - of which I installed the ROM from http://xdaforums.com/showthread.php?t=2678142 This install of SlimKat with F2FS worked. I then wiped everything and then installed AutoDroid and AutoDroid worked (on both grouper and tilapia).

But then I found that OTG wasn't charging (on either grouper or tilapia). I have two cables and they both work on USB-ROM so I am pretty confident it isn't the cables. I looked at the kernel and it said that LegoKernel was installed on the AutoDroid ROM. I looked back at the SlimKat ROM and it was the same LegoKernel. I was suspecting that the LegoKernel that was installed didn't support OTG but couldn't find any posts to verify either way. In the first post it says AutoDroid ROM uses Kangaroo Kernel, and so I also didn't know why LegoKernel was installed when I had the AutoDroid ROM installed, but just suspected it was somehow leftover from the SlimKat ROM install. I couldn't find where to get the Kangaroo Kernel either to try to install that.

So then I went back to factory image to restart it all over again and tried AutoDroid again with F2FS using the instructions in the first post and the same thing - stuck at Google logo. I am now guessing that the Kangaroo Kernel that is in the AutoDroid ROM isn't F2FS compatible and that's why I'm getting stuck at the Google logo ?

So then, I wiped everything again and converted back to EXT4. I then installed AutoDroid with EXT4. Now it boots past the Google logo, so now I am pretty sure it is because Kangaroo Kernel doesn't like F2FS since it boots past the Google logo. But now it is stuck in boot loop at the SlimKat logo (on AutoDroid ROM). I've tried wiping dalvik and cache again and still stuck at logo for like 20 minutes.

I've been at this for like 3 days now and frustrated. Am I supposed to have Kangaroo Kernel? Am I supposed to be on F2FS?

Any suggestions? What am I missing here?
[Nexus 7 Android Development] papinist:
I can't help you with detailed steps, but I changed to F2FS first, then flashed autodroid (tilapia) and all is working (OTG charge/fast charge/firm sleep/etc.).

Yes the guide in first post didn't work for me too, but can't remember exactly what guide I followed..
[Nexus 7 Android Development] 1dirtypanda:
So I just did this:

1. Format, Wiped everything.

2. Kept partitions as ext4

3. installed Slimkat for tilapia - slim-tilapia-4.4.4.build.8.0-official-6949.zip (which my understanding is not a f2fs build).

4. booted it fine. i checked the kernel version there. (forgot to write it down)

5. recovery, wipe everything (didn't do a format).

6. installed autodroid and gapps.

7. boots up

BUT the kernel looks to be the same as the one on Slimkat (non-Autodroid). On my autodroid install it says 3.1.10-Slim-4.4.2-KK-beta.1.6+autobuild@slimbuild #1. So I'm still not see Kangaroo Kernel, or am I not supposed to?

Edit: so then I did this:

1. Convert to F2FS.

2. Flashed an older SlimKat 4.4 from http://xdaforums.com/showthread.php?t=2678142 as maybe this had a different kernel. This flash worked under F2FS and had 3.1.10-Slim-4.4.2-KK-beta.1.6+ andrea@andrea-Aspire-V3-571G #91

3. I then wiped system, data, cache and flashed AutoDroid 1.2 using F2Fs.

4. Boots up ok and now I have the correct ROM but the same kernel as in #2 above. I noticed that it does say KK there. Does this mean Kangaroo Kernel?

Edit #2: Kernel isn't installing properly for sure.

I went back to factory stock KTU84P.

Left it on ext4.

Installed AutoDroid-1.2 on ext4.

Actually booted up fine, surprisingly.

Kernel shows factory stock kernel - 3.1.10-g1e42d16 android-build@vpbs1.mtv.corp.google.com #1 Thur Mar 13

[Nexus 7 Android Development] unknownprotocols:
Negative. A car usb port is unlikely to work. Will probably work for an iPhone though. You need to connect the tablet another way, like Bluetooth, or using an rca to phono plug/headphones cord if your car has an Aux input of some sort.

As far as I have seen, the dev has upgraded, and doesn't use the n7 in his car anymore. Seems unlikely we'll see an update for this rom unless we can convince the dev with donations, or one of us learns to build roms. (looking for a teacher btw if anyone wants to help)
[Nexus 7 Android Development] ryanjv:
to play from google music this is correct. But if you have the media just stored on the tablet, it depends on what the car is because their infotainment will be set up differently. In some brands, if you set your device to MTP, you can plug in the device, source to USB and can browse the folders as if it were a flash drive
