easycapdc60

I use the linux driver easycapdc60 for FriendlyARM Tiny6410.
When used with mencoder, I do not get even a frame from the video capture
device. Any help will be appreciated. 

Below is the diagnostic message :

What linux distribution have installed on your board?

Can you tell what you have done till yet?

Hi Pratik, thanks for your reply.

Installed on board is a linux distribution from FriendlyARM based on the
kernel linux-2.6.36. I have tested easycap hardware and the easycapdc60
drivers on my desktop Fedora14 with success. Hence any hardware fault is
ruled out. 

On Fedora14 desktop, I compile the easycap driver as VIDEODEV client, and
then later an independent module. Both way works for Fedora14. I did the
same for my board, but without success. On the board, the output from
mencoder and from log file are as described in the first post. 
In this way, I rule out fault due to dependency on VIDEODEV module.

I have already turned the DEBUG level in the install.sh script to LEVEL 9,
and based on the debug message, I have no clue how to proceed on.
At this point, I am running out of ideas where to look for faults.

Any advice will be appreciated.
Thanks.

To be more concrete, 

Mencoder is used to capture video through easycapdc60. FriendlyARM tiny6410
is an ARM device. Easycap is installed as an independent module and appears
as /dev/easycap0. Any help will be appreciated.

Hi Pratik, 
I have received a reply from the easycapdc60 driver author. He suggested
that I should check if my ARM board's USB host is 2.0, as easycap only
works with USB2.0.

It turns out that the USB host on TIny6410 board is USB1.1. >_<!
That explains why I can not get any valid USB data stream from the video
capture device~

Do you think if  there is any FriendlyARM product with USB2.0 host?

Dear hunglun,
I am using Mini2440. I am also getting green frames only. I have tried with
mplayer. 
Do you get these two things after plugging EasyCapDC60?
1. /dev/easycap0 having link to /dev/video0
2. /proc/asound/EasyALSA0
If you dont get EasyALSA0 then you have to check the udev rules for
easycap. You might have downloaded driver source from sourceforge, you can
find in that see 

#-----------------------------------------------------------------------------
#  WRITE CONFIGURATION FILE(S) FOR udev
#--------------------------------------------------------------------------

section in install.sh

My another question, is your board able to play video files without any
problem? I'm trying these things since last month.

Hi Pratik,

easycap module can be compiled as VIDEODEV client or as an independent
module. This option can be chosen in the install.sh :

CLIENT = 0

When insmod the VIDEODEV client version of easycap module, /dev/video2
appears on my system.
When I insmod the independent version of the module, it appears instead as
/dev/easycap0.

I did not pay attention to the sound part, as I just want to record video
without sound. 

As for playing video, I can actually play a sample video using the built-in
video player on Tiny6410. It is a mpeg video. Strangely, those video I made
myself on desktop in avi format can not be played on Tiny6410.

My problem lies  more with the hardware part; USB1.1 host seems to be too
slow for the minimum resolution that easycap offers.

Dear hunglun,
I have tried with mplayer I got only green screen.
Then I tried with gstreamer it is working but not showing on display.
Do you have any idea how to add USB 2.0 ob board or Do we need to look for
other development board?

Thanks

Hi Pratik,
as I am having problem with using easycapdc60 on my USB1.1 host, the
options I have seem to be:
1. get another A/V to USB converter that support USB1.1
2. get a board with USB2.0 host
3. develop/find for easycapdc60 another driver that support USB1.1

Option 3 is probably the most time consuming.
Option 2 is probably more expensive than option 1.
I intend to find out more about option 3; see if it is too difficult to get
another driver that support USB1.1

Regarding your problem getting mplayer to work with easycapdc60,
you have a few suggestions:
1. have you got mplayer and easycapdc60 to work on desktop linux? it is
always easier to get it work on desktop first, before cross-compiling it
for ARM architecture.
2. try to look at the debugging message output by easycapdc60. Use "dmesg".
You may find out more about the cause of the problem.

Good luck!

Dear hunglun,
 I want to use Easycap DC60 as it is very cheap compared to others. And we
dont have another driver that supports USB1.1 host. So I am looking for
some other board which will give me necessary things.

I have tested EasyCap and Mplayer on my desktop. It works perfect. My dmesg
output is also fine, so no issues with driver but only that USB1.1
Thanks

Dear hunglun,

hello hunglun/Pratik,

Can you please tell us how did you compile easycap for mini6410.  I tried
it without any success.

Thanks and regards,

Prathamesh.

Prathamesh,
It requires USB2.0, It will not work on USB1.1 though you can compile it
successfully and insert Kernel module.
