[KERNEL MODULE] CM 10.1 Easycap Module

dcplaya · Mar 14, 2013

I have built an Easycap module for CM10.1 on the N7. This module should allow anyone to connect an Easycap and with the correct software, view video from the easycap. This is only for the Syntek EasyCAP (USB ID 05e1:0408) and no others.

This will only work on kernel version 3.1.10-gfcf72bf-dirty. You can check your kernel version under Settings --> About Tablet --> Kernel Version

To install, copy the easycap.ko to /data/local and then install the module by running

Once the module is installed and the device is plugged in, there should be a /dev/video* (where * can be a 0, 1, 2, 3, 4 or 5)
Depending on how you access /dev/video* you may need to chmod 0666 /dev/video* to allow access.

EDIT: Please see Rage2 post on page 9. I have not tested his release yet but once I can confirm, I will update the main post. Big thanks to Rage2!

EDIT2: Newest update from DmitrySmol and Adman. Ill try to keep the main post updated with links and news.

New version of CarCam out. See http://rootzwiki.com/topic/39717-kernel-module-cm-101-easycap-module/page-15#entry1443034

Thanks Adman and DmitrySmol!

dcplaya,

Same result here. Insmod worked with your module. Prior versions gave me the "Exec format error." Running Timur ROM on talapia. Have the correct Syntek video capture device.

Sorry I cannot be more help other than to second your result...no /dev/video*.

I also have a webcam. This worked fine. Got /dev/video0 when plugged in to USB hub. Had to chmod 666 and set proper video settings (carcam_api9.apk) and it works.

Clearly you are very close! Let me know if I can do anything else to help. Once this works I am ready to install!

c,

The Easycap is working fine, but sometimes i get only a black screen (/dev/video0) is available and the permissions are corret.
i think there is a problem with the driver... when i listen online music with tunein there is no problemes, but when i start the carcam with easycap than the musik is lagging.
when i close the carcam app, the lagging problem still exist until i restart my tablet.
maybe the driver closes the videostream not correctly?
i checkt the CPU / RAM usage, when my music an tablet ar lagging but usages are okay.

a other question is, i used the easycap.ko from USBROM (build 20130302) than i took a hex editor and changed the version to the newest (current release).
the original easycap from USBROM is only 80KB in size and the easycap.ko in this thread have 900kb... it looks strange... maybe some other problem?

here is my kernel log, first the easycap works fine but than the devices shows only black screen.

hi,
i think You have lagging, because carcam_beta have a lot debug info

. pls send me logcat. i will prepare soon alfa version.

dcplaya · Mar 18, 2013

Im running a not released kernel/module and I am getting no lags at all. I am also setting permissions via my modified ramdisk which isnt very secure but it was the easiest to setup and test my module and the camera hardware.

@Dra4g0n
Are you running the latest USBROM with that module from an older ROM?

I have also added a memory leak patch I found online to my version of the un-released module
https://github.com/d...e90464efbd896ec

I haven't released it yet because I cannot get it to run on USBROM's kernel, and I havent had time to to keep working with possible fixes. And no one seems to be able to answer what is causing it from my log (shown in the first post)

This has slowed down a little bit, I just havent had the chance to do tests lately.

Hydro · Mar 26, 2013

[background=rgb(245, 245, 245)]Hi[/background]

[background=rgb(245, 245, 245)]I saw on Timur topic that easycap driver won't be support anymore

[/background]

[background=rgb(245, 245, 245)]So if i understand with your file i can use easycap STK1160 like old timur rom ?[/background]

dcplaya · Mar 26, 2013

If you look at my first post all of the way, I am having issues with my module running under Timur's kernel. I am currently waiting for the next release of his rom before I try a new build of the kernel.

Kuchar09 · Mar 26, 2013

Well I just ordered my easycap and should have it monday! Thanks for putting this together dcplaya!

DmitrySmol · Mar 26, 2013

dcplaya, good news.
we have built stk1160-standalone for RK3066 3.0.8+.
Maybe You can try to build it and for Nexus?
just remove ac97 support for this driver (remove stk1160-ac97.o in makefile and comment all calls ac97, You will see it in build process)
also build and insmod next modules:

saa7115
videobuf2_core
videobuf2_vmalloc
videobuf2_memops

dcplaya · Mar 26, 2013

Isnt this older than what is in the kernel now? Or is the one in the Android kernel (v3.1.10) and this one different?

DmitrySmol · Mar 26, 2013

It is different(next life of easycap driver). try to build it.

P.S. easycap more info.

dcplaya · Mar 26, 2013

Im having issues getting the videobuf2 components to build as modules. Any idea how its done?

dcplaya · Mar 27, 2013

Everything seemed to load except the stk1160.ko. When I insmod it into the kernel it crashed the kernel and caused a reboot. I grabbed the old kernel log though and I am looking into it

Hydro · Apr 8, 2013

Any News ?

dcplaya · Apr 8, 2013

Timur and I think it might be a build environment issue so I will be installing Ubuntu 13.04 (he uses that) in the hopes it solves the issue.

Ska77 · Apr 23, 2013

Hi dcplaya,

I'm trying easycap.ko but I get same error: "Exec format error"
I use kernel 3.1.10-gfcf72bf and easycap.ko in this post (file size is 105.336 bytes) I have tried also easycap.ko found on Timur's kernel post (file size of 98.796 bytes) without success.
Which is the situation? Easycap can work? Do you need help on development (i'm a firmware developer)? If yes, it could be interesting explain how to build module
Thank you in advance

amurchick · Apr 25, 2013

Hi, where to get easycap.ko module for 3.1.10-g3ab72d2-dirty?

dcplaya · Apr 30, 2013

Guys, I can make a new easycap driver for Timur's latest ROM but most likely it will not work. I will post an updated link later today with it. But I have a feeling it will result in the same issue as before.

Ska77 · May 3, 2013

@dcplaya

I was able to rebuild easycap.ko and insmod to work, but when I attach easycap, I get error message during _video_register_device in v4l2-dev.c, line 559. This is caused by vdev->release equal to NULL.
I've missed something? Do you have already encoutered this kind of problem?

Thank you and I hope to help you in development (can you also explain me what you mean with "But I have a feeling it will result in the same issue as before."?)

dcplaya · May 3, 2013

Ska77

That is (one) of the same issues I have encountered. Somehow v4l2 has been changed causing a variable to point to a null value which is a big no no.

What version did you compile Easycap for? Was it Timur's 5/2 beta release?

Ska77 · May 3, 2013

I'm not able to answer you, I get sources from https://github.com/CyanogenMod/android_kernel_asus_grouper.git as explained in http://mehrvarz.github.io/building-nexus-7-kernel/
Do I have to download from https://github.com/mehrvarz/android_kernel_asus_grouper.git ???

dcplaya · May 3, 2013

I use Timur's kernel sources but maybe I can try to use the stock CM sources.

The kernel version is the text you enter in the Makefile, usually something like

Code:

KERNELRELEASE = "3.1.10-gae45ce1-dirty"

Ska77 · May 3, 2013

Ok, I've entered "3.1.10-g3ab75d2-dirty", which is what I see in Tablet->about
I've built kernel but used only module easycap.ko.

I'm very interested in easycap work, I'm available to help in development!!!

Kuchar09 · May 10, 2013

Hope you guys can figure this out! I tried but I'm so horrible with linux that I didn't get very far. Good luck!!

Ska77 · May 10, 2013

If I'll do, I'll share it!
But for now, I'm blocked. I'm trying to get latest kernel sources used by Timur and trying to make, after kernel build, zip file to use with Clockwork Mod.
Can you help me? Do you know links where can I get help?

Kuchar09 · May 14, 2013

Hey sorry didn't know you responded! Unfortunately I'm not much help, the only person I would think would be helpful is Timur but idk if he really wants to help with the whole backup can thing. Sorry I couldn't be more help

Ska77 · May 14, 2013

Don't worry, Kuchar09, I'm going to evaluate to use USB webcam instead of usb grabber.
To increase angle view (usually small in USB webcam) I can add a len and I'll use hub usb to increase cable length.
I saw a lot of time your thread but I haven't understood if rearcam works with timur USBROM and which usb camera you've used.
Thank you

nexus-fan · May 14, 2013

you can find more here: http://droidpercepti...ttached-update/
(its really simple to connect usb camera)

this could help http://www.hanselman.com/blog/DIYMakingAVeryWideAngleWebcamOnTheCheap.aspx

d1dd1 · May 25, 2013

Any news here ?

A N7 with backup cam function would be so awesome

Are you aware of the driver-free UVC USB grabber which acts like a usb webcam ?

http://febon.blogspo.../2012/02/1.html

and here:

Sadly the company wants around $80 including shipping.

Maybe we can get a cheaper price when we make a groupbuy or sth. like this.
Or another option would be to collect a bounty and try to find a dev to make the easycap work for our N7.

Adman · May 30, 2013

D1dd1 -

Thanks for the info and link. I will be placing an order. I did come close to getting the EasyCap to work, but in the end I went toward getting a USB camera working first. This may have paid off as the Febon grabber should now be "plug and play" for me.

I have my backup cam working well with a USB video camera. I modified SimpleWebCam in several ways:
1) displays in "fullscreen." No title bar, back/home/recent buttons hidden.
2) image is horizontally mirrored - necessary so the image appears oriented correctly (like a mirror)
3) app does not show up in recent apps list
4) app is started by External Keyboard Helper which receives an F8 keyboard code from a JoyConEx (sent on sensing power from reverse light)
5) app listens for F9 code which is sent from JoyCon and decoded by EKH when no longer in reverse. So app opens very quickly when reverse engages and closes when reverse is disengaged.
6) the prior app that was running is restored when the app closes

Finally, I have figured out how to permenantly set the permissions on the /dev/video0 file. So, all in all, it works exactly as a good reverse cam should.

I will do my best to document all this and to share the code and app. As I will likely start a rootzwiki forum as well as posting the code to github - both of which I will have to learn how to do, it won't happen until this weekend at the earliest. Once done I will also post to Tumur's forum.
