Description Casimiro de Almeida Barreto 2004-05-28 10:00:57 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; pt-BR; rv:1.6) Gecko/20040510

Description of problem:
Images captured from webcam (creative webcam III) are "repplied" with
3 times with 1/3 of correct width, ie., when rendered we see 3 times
the correct image, each compresset to 1/3 of correct width.

I guess that the problem is that those cameras work with 12bpp YUV
instead of 16, 24 or 32 bits and videodev is "adjusted" to 16/24/32bpp.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. get a webcam viewer (Camorama, Powa, gqcam, etc...)
2. compile it, install it
3. execute and "voil�"...
    

Actual Results:  The image holds three copies of the intended image,
compressed in width.

Expected Results:  The correct image

Additional info:

Tested with Creative webcam (OV511 driver)
Comment 1 Dave Jones 2004-05-28 10:27:37 EDT
can you get the ov511 related msgs from your dmesg ?
I just tested with a WebCam3 using an OV7620 sensor, and it works fine
when I view it with xawtv, or use camE

I'd also suggest you try viewing with xawtv. If that looks ok, it's
a bug in the apps you're using.
Comment 2 Dave Jones 2005-04-16 00:42:24 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
