Can you send me your code via EMail. This way I can reproduce the issue here.

Manabu ONO: unicap 0.9.6 and UCView 0.30 released!

I am using ImagingSource "DFK 21AF04".
Your original smallapp.c works OK with the above device which just displays the image.
Also devce_info.c and device_property.c works.
But it fails when opening the device on my modified smallapp.c.
I guess there is not anything wrong in my modified smallapp.c because it has run stable for last 3 years.
Thank you for quick reply.

I am very sorry about that

Can you tell me which video capture device you are using?

Dear Arne.
With unicap-0.9.6, my own app does not work, which has worked fine for last 3 years until 0.9.5.
My own app is a modification from smallapp.c.
It just adds image capturing on smallapp.c.
When trying to open the device (unicap_open) for image capturing,
error "failed to open device ....." happens.
According to your change release,
- fix cropping for unicapgtk_videodisplay
- minor fixes to unicapgtk property dialog
I suspect these changes affect the error.
I hope you to fix the issue.
regard.

Arne Caspari: Software updates for The Imaging Source CMOS cameras

nospam@example.com (Arne Caspari) — Thu, 21 May 2009 20:19:09 +0200

The instructions here are obsolete. The The Imaging Source CMOS cameras are now supported by the euvccam_cpi plugin ( available via the download sections from the project homepage ).

Hi,
I am trying to get this drive to work in 8.10 and before installing this driver I installed the latest uvcvideo. I can build and install the driver but if I do modprobe I get:
FATAL: Error inserting uvcvideo (/lib/modules/2.6.27-11-generic/kernel/ubuntu/media/drivers/media/usbvideo/uvcvideo.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and dmesg reports:

Victor: Updating UCView and Unicap on the ASUS EeePC

nospam@example.com (Victor) — Fri, 23 Jan 2009 19:50:24 +0100

Hi, I just tried to update the UCview on the eeepc 701 but after following your instructions I got an error: error processing /var/cache/apt/archives/ucview-asus-icons_0.22eeepc0_i386.deb (--unpack)

And then: sub-process /usr/bin/dpkg returnet an error code (1)

Then I tried to use UCview and it is crashing when I click the 'record' button to stop the recording.

As I can see it can record but when I try to stop the recording it freezes.

I really apreciate if you could help.

Matt Whitlock: Unicap 0.9.3 and UCView 0.22 released

nospam@example.com (Matt Whitlock) — Mon, 27 Oct 2008 09:25:28 +0100

Okay, I posted a revised ebuild that does not give the option to enable avcodec support in unicap.

nospam@example.com (Arne Caspari) — Mon, 27 Oct 2008 09:10:30 +0100

I would recommend to leave avcodec support disabled in the ebuild if possible as it might break in the future. I do not think there is any software using the avcodec support.

Comment script ate my text, which was enclosed in angle brackets.

Those paths are libavcodec/avcodec.h and libavutil/avutil.h.

Thanks. I personally would always prefer to use Theora, but I ran into this bug while authoring unicap and ucview ebuilds for Gentoo.

http://bugs.gentoo.org/show_bug.cgi?id=175881
http://bugs.gentoo.org/show_bug.cgi?id=244586

Of note, I also had to patch the #include lines for avcodec.h and avutil.h to conditionally use the new paths being pushed down from the ffmpeg project: and .

Thanks, I will have a look. The code in question is disabled by default.

The avcodec module of UCIL is currently not very well supported and mainly untested. It will get replaced by a new AVI module some time in the future - until then I recommend to use the Theora encoder instead.

There's a typo in ucil_avc_avi.c on line 586. It says UCIL_FOURC but should say UCIL_FOURCC. This typo causes the emitted shared library to have an unresolved symbol UCIL_FOURC, which is reported as an error when linking ucview against libucil.so.
