Built kernel module on two machines, an Atom netbook with a beta release of 
Ubuntu 13.04 and a Pentium D 2.8ghz machine with 12.04.2 LTS, each now updated 
to 3.8.0-19-generic. Device uses firmware smi2021_3f.bin.

I have the modules loading automatically from /etc/modules. 'Motion' loads the 
device fine, /dev/video1, auto-selecting a resolution of 720x486. But the 
syslog gets spammed with thousands of messages:
[ 1776.273738] smi2021::smi2021_buffer_done: Dropping buffer, Buf->pos: 0, 
trc_av: 1
[ 1776.273790] smi2021::smi2021_buffer_done: Dropping buffer, Buf->pos: 0, 
trc_av: 1
[ 1776.273842] smi2021::smi2021_buffer_done: Dropping buffer, Buf->pos: 0, 
trc_av: 1
[ 1776.273894] smi2021::smi2021_buffer_done: Dropping buffer, Buf->pos: 0, 
trc_av: 1

This caused rsyslog to take up a lot of CPU, so I disabled this service. CPU is 
important because I'm trying to have this Atom netbook record video at the 
highest frame rate it can, using Motion.

The system is working otherwise, at first glance. But the kernel will lock up 
periodically. Sometimes it comes back in a few seconds. Sometimes I get kernel 
messages about the watchdog timer or another process segfaulting during these 
freezes. If frozen, pulling the USB device from the computer returns it to a 
usable state.

Capturing video to a file using the userspace tools does not reveal any 
immediately problems, but this isn't useful to me as I need the video to be 
available to Motion.

Any ideas? Any debugging info I can provide?

It compiles and works great on osx. (user mode)

Just had to change the location of the firmware file. And remove the -vf 
parameters of mplayer.

Thanks a lot!

Cheers

Joan

I've downloaded the last git easycap-somagic-linux source version.
After, i've compiled and installed the easycap kernel diver without any problem.
I've extracted and installed firmware from 
SmiUsbGrabber3E/xp/SmiUsbGrabber3E.sys without any problem, whit 
somagic-extract-firmware tool.
When i attach the usb device this is the kernel messages:

Using userspace somagic_capture utility the situation is identically.
the cose is looped in this while loop, witouoit any output:

}
Can i do something?
Thanks in advance.

Hi,

I have managed to initialize the device but once it comes to compiling and 
installing the kernel modules I get the following errors. Could anybody help 
shed some light on this? I am running Ubuntu Server 12.10. Thanks

When I run sudo make I get

ake -C /lib/modules/3.5.0-22-generic/build M=/home/thomas/easycap/easycap-soma$
make[1]: Entering directory `/usr/src/linux-headers-3.5.0-22-generic'
  Building modules, stage 2.

Which I presume is just fine, then when I run sudo insmod somagic.ko I get

insmod: error inserting 'somagic.ko': -1 Invalid parameters

and dmesg shows

I've Googled it and tried "sudo modprobe videodev" before insmod but it doesn't 
work. Any help would be greatly appreciated.

GettingStarted uses twice "libgrypt11", should be "libgcrypt11".

Hi,
I've a problem with this driver.
I installed latest version (1.1) on a ubuntu 13.04 64bit (kernel 
3.8.0-19-generic).
Compiled the kernel modules and loaded.
But when I execute a "somagic-capture --test-only", I get this message:

Any help?
Thanks a lot.

Compiled easycap tools using the latest source code file.  I'm on Ubuntu Natty 
Narwhal. It all makes and installs fine, I can extract the firmware data to 
/lib/firmware/somagic_firmware.bin as per the instructions, but when I run 
somagic-init I get the message

"Firmware file '/lib/firmware/somagic_firmware.bin' was not recognized"

Has anyone else have or had this prob;em and found a way to resolve it?  I've 
gone through the whole installation procedure several times, checked 
permissions on the firmware file and still the same.

Hi, I've compiled the user code and kernel code on/for my raspberry pi. I seem 
to get slightly better results using the user code but I do not seem to be 
getting whole frames and the frames seem to be drawing over each other. (see 
attachments)

I am running:
# somagic-capture --iso-transfers=85 | ffmpeg -f rawvideo -pix_fmt uyvy422 -s 
720x576 -y -an -r pal -i - -f image2 foo-%03d.jpg

I am not sure what iso-transfers mean, but the higher the longer i get almost 
full frames (85 gave me about 20 good frames in a row @ 4 fps)

I think there might be some kind of sync issue or the device is not sending 
whole frames.

Is there a way of modifying the code so it only outputs whole frames?

Also as a side question, is it possible to get somagic to scale each frame?

Attached are some captured frames, including the first frame, a good frame and 
a few corrupted frames.

Let me know if more information is required. I am happy to test/try other 
things and report back if i can be of any use.

Cheers.

In line 1111 of kernel/somagic_video.c there is:

vma->vm_flags |= VM_RESERVED

Since this flag no longer exists this line should be removed.
Module seems to work fine without.

Documentation:

The mplayer example shows video only. Please include examples that combine 
sound 
captured from a pulse/alsa input with the video. Most applications will also 
require sound input. I realise that sound capture from the DC60 isn't 
implemented yet, but sound capture should still be possible from the existing 
sound card.

hi ,
im using Somagic D60 device, for video output its working fine.
but there is no sound.
im attaching the command:

somagic-capture | mplayer -vf yadif,screenshot -demuxer rawvideo -rawvideo 
"pal:format=uyvy:fps=25" -aspect 4:3 - -ao pulse

video is ok but no sound...

im having somagic-easycap_1.1.tar file.
I've extracted this tar file. i found somagic-audio-capture.c please anyone 
help me for compiling it.

Regards 
Rohit

Dear all,
I'm currently working on an open source project that works with gstreamer . I 
wanted out put of my camcorder as v4l2src. I found this easyCap is promising to 
work.

But when I ordered it didn't work out of the box. Details of devices are 
follows.
Model No. : DC60-2021 Version 3.1C win 7-64

When I do lsusb
Bus 002 Device 008: ID 1c88:0007 Somagic, Inc. SMI Grabber (EasyCAP DC60+ 
clone) (no firmware) [SMI-2021CBE]

I tried to do what your site http://code.google.com/p/easycap-somagic-linux/ 
says.

But when I try to do
sudo somagic-extract-firmware SmiUsbGrabber.sys
I get error
Somagic firmware was not found in driver file.

What I am doing wrong? How to fix this? Please be kind enough to help me.
Thanks in advance.

Screenshots of the windows software for the EasyCAP002 suggest that it's 
possible to capture from all 4 inputs simultaneously, though I assume at 1/4 
the standard NTSC resolution.

It would be super cool if this linux software supported that mode :)

(I have capture from any of the individual inputs working fine from a 
"1c88:003f Somagic, Inc." device)

Hi,
I followed the getting started guide, and almost every steps works for me, 
until I get to the end and try to capture some video.

I am on: Lubuntu 13.10 64 bit 

My capture device is a version 3f.
I tried the xp and vista firmwares from the official CD

Is there any info I can gather to find out what is going on here? I would like 
to help!
Please let me know
Thanks

Bart

I have a Pluscom device reported by lsusb in this way:
<<
Bus 001 Device 009: ID 1c88:0007 Somagic, Inc. SMI Grabber (EasyCAP DC60+ 
clone) (no firmware) [SMI-2021CBE]
>>

I followed the instruction reported for other device but I found a difference: 
it uses "SmiUsbGrabber3F.sys" as firmware.

Is it possible to adapt this project to work with this device too?
If it's possibile and I can do something for you, contact me.

Thanks.

Hi, all

I followed the instructions and it works well on my PC.

I got an odroid-u3 board

http://hardkernel.com/main/products/prdt_info.php?g_code=G138745696275

Every step goes well, but when executed somagic-capture,
I got images below

What steps will reproduce the problem?
After compiling the somagic kernel module I reboot but it doesn't show a new 
audio device in the aplay list

What is the expected output? What do you see instead?

f1nk@f1nk:~/ciso-1.0.0$ aplay -l

What version of the product are you using? On what operating system?
Somagic  Bus 001 Device 005: ID 1c88:003f Somagic, Inc. 
On ubuntu 13.10 Saucy


Please provide any additional information below.
I compiled the most current modules for the device but the only thing that 
shows up is the video capture not sound.

What steps will reproduce the problem?
1. sudo insmod somagic.ko
2. qv4l2 /dev/videoX
3. Start video capture
4. adjust brightness to 0.
5. Stop video capture
6. Set brightness to something
7. Start video capture again

What is the expected output? What do you see instead?
The brightness skips down do 0, when we start a capture again.

Expected behavior. New brightness level is set!

What steps will reproduce the problem?
1. Plug in the Somagic USB device, it shows up properly in dmesg:

[    6.630083] smi2021 2-1:1.0: Somagic Easy-Cap Video Grabber

2. Run VLC
3. Select Media -> Open Capture Device
4. Choose video device, here /dev/video1, and click play (Video playback starts)
5. Select again Media -> Open Capture Device
6. Choose some random audio device and click play

This will trigger the panic. Always. It's easily reproducible for me.

I downloaded and built the smi2021 module just today according to the 
"BuildingKernelModule" section in your wiki. I built a whole kernel from source 
on my Ubuntu 14.04 and installed the debs.

Screenshot of the panic is attached. Sorry for the bad quality, taken with a 
budget phone :)

Hello Everybody
I am trying to install appGRABBER V5 usb-capture-video to convert VRC tapes to 
DIGITAL with my Linux Mint 17.1

I did all the steps:

lsusb first told me:
Bus 002 Device 003: ID 1c88:0007 Somagic, Inc. SMI Grabber (EasyCAP DC60+ 
clone) (no firmware) [SMI-2021CBE]

when i installed:
    somagic-easycap-tools_1.1_i386.deb 
and     somagic-easycap_1.1_i386.deb 
with Gdebi
and I installed the .sys file
of course i got the /lib/firmware/somagic_firmware.bin

then, after "sudo somagic-init"
lsusb tells me:
Bus 002 Device 004: ID 1c88:003c Somagic, Inc. SMI Grabber (EasyCAP DC60+ 
clone) [SMI-2021CBE]

I plug everything in the usb..
I open VLC, SMPlayer even CHeese. but i only got to see video-0 which is my 
webcam..

Why can i see an video-1 for example to choose this usb-device? 
I am lost, i don't understand what should i do now...

Please, could you tell us in the GUIDE?

Thanks a lot.

my dmesg:

and this is very weird because when i tried to open it in TVtime ( i installed 
with software center) when i choose NTSC only my webcam (i am with a laptop 
with webcam integrated) appears as device... and when i choose PAL...FRAMES TOO 
SHORT FROM uvcvideo "I can't open device /dev/video0"

I don't know what to do... i need another device /dev/video1... and i need to 
know why it doesn't appears if i did all the steps well without errors..
Please, more information, or help.

Thanks a lot.

Hello, today I received:

ID 1c88:0007 Somagic, Inc. SMI Grabber (EasyCAP DC60+ clone) (no firmware) 
[SMI-2021CBE]

from dealextreme. Problem is that CD can't be read on my PC, and copy of 
Setup.exe file from another PC gives error while instalation. I think data are 
damaged, is there a way to get Setup.exe or whatever from any of you? Thanks.

Hi I want to use the easycap-somagic Stick with an ARM v7 Device and I do not 
know much about cross compiling, the only I have done so far was cross 
compiling a Linux Kernel for Android.

Is it possible to cross compile the same way but for ARM?

Hello and than a lot for the job and the help you provide for end-users,

I'm using debian wheezy.
I have dowloaded somagic-easycap-tools_1.0_amd64.deb and 
sosomagic-easycap_1.0_amd64.deb and i have installed them with dpkg -i without 
problems.
I haven't used the 1.1 version cause some dependencies aren't satisfied.

Here the result when i plug the usb device :

ls -l /lib/firmware/

It seem to work fine but i can't capture at all.

I compiled easycap+tool from git and got device 'working' (video flickers very 
much, no audio). 
Device/chipset is this one: SmiUsbGrabber3F/xp/SmiUsbGrabber3F.sys

And next run gives:

What version of the product are you using? On what operating system?
easycap dc60 on fedora 16, I've also tried fedora 20, smae problem.


Please provide any additional information below.
I've been slogging at this for days, maybe this device is impossible install, I 
don't know. I can do all the steps at 
https://code.google.com/p/easycap-somagic-linux/wiki/GettingStarted
and device initialises as 1c88:003f but I cannot get /dev/video0 no matter 
what. If anyone has a step-by-step for fedora that would be good.

GettingStarted -> Extracting firmware:
 ..."Drivers/Setup.exe", on the EasyCAP installation CD...


On my CD (for SmiUsbGrabber3F/xp/SmiUsbGrabber3F.sys) directory name is without
