PS3Eye on Debian

PS3Eye on Debian

[xelapond]

Hello,

I have been trying to get my PS3Eye Camera to work on Debian, and to partial
success.  I did as recommended
here<http://forums.ps2dev.org/viewtopic.php?t=9238&postdays=0&postorder=asc&start=90&sid=04c17e156208a7226117b24df91b2fd6>and
got the gspca sources from
http://linuxtv.org/hg/~jfrancois/gspca/, and compiled those.  It compiled
successfully(it complained about __memcpy once, but nothing big).  I can now
access the camera through /dev/video0.  It works fine in
gstreamer-properties, but when I try to open it in anything else(for
instance mplayer), I get errors.  I have posted the output of mplayer below:

alex@Andromeda:~$ mplayer -vo ov534 -ao alsa -tv

Any ideas how I can get this to work?  Ultimately I would like to be able to
use the camera within openFrameworks, which uses unicap.

Thanks!

try removing -vo ov534, it is definitely wrong.

If unicap can handle yuyv then it will work, otherwise you have to use
libv4lconvert in some way.

Hi Alex,

As Antonio mentioned, remove '-vo ov534' and it should work.

I tested unicap using ucview and it works with the Playstation Eye
just fine.

Thank you both for your replies, I got it to work with the following
command:

mplayer -vo gl -ao alsa -fps 50  -tv driver=v4l2:device=/dev/video0
tv://

How were you able to get this to work?  On my machine ucview complains
it can't start the video signal, and just shows me a yellow screen.
Here are the errors:

(ucview:26333): GConf-CRITICAL **: gconf_client_set_string: assertion
`val != NULL' failed

** (ucview:26333): WARNING **: Failed to start video capture


Any ideas?  This is the first time Google has ever failed me in
searching for errors, it returned literally no results.

I'm really sorry if this got posted twice, I was using the GMail online
client, which isn't the best for mailing lists:)  I'm now using
Thunderbird, so it should be OK.

Thanks!
