(SOLVED) Skype video not working - black screen

[snowflake_nz]

Re: Skype video not working - black screen

Hi there
sorry for being so quiet. Had to go fetch my daughter from kindergarten.
Okay, what's got me stumped is that the camera is there and working perfectly when I run this command in Konsole LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

Anyway here is the output of lshw:

Re: Skype video not working - black screen

I must be blind. I don't see anything in the lshw listing that I am familiar with and to which I could point as the webcam device.

Anyway, you say that when you run your camera in a Konsole with:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

it "works perfectly". Then, as a quick solution to your problem, just edit the Skype menu option and make that line the command line the command text box on the General Tab. Use this command instead:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype

to replace the word "skype" currently in the menu command text box. (you forgot to include the skype binary in your msg but obviously included it in the Konsole when you ran skype).

Using something similar to what you did in the Konsole is exactly how Skype is run on MY 64bit Kubuntu 10.4. A bash shell script called "skype-wrapper" is used as the command in that menu command text box. It contains the following code:

.....
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so QT_PLUGIN_PATH=/usr/lib32/qt4/plugins /usr/bin/skype "$@"

That command won't work on your box because it is already running a 32bit OS and skype is a 32bit application, so you don't have a /usr/lib32 directory (or shouldn't have) on your system.

Re: Skype video not working - black screen

Just a wild idea, but what does

lsusb

show.

[GreyGeek]

Re: Skype video not working - black screen

Except that her camera is internal, not a USB device. But, who knows. It's worth a try..

[Detonate]

Re: Skype video not working - black screen

I was thinking that even though it is an internal camera, it still might be wired up as a USB device, even though I have never seen that before.

[snowflake_nz]

Re: Skype video not working - black screen

Hi Detonate & GreyGeek

1) The actual Konsole command is LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

2) Output to lsusb is as follows.

Sure thing Detonate.
You enjoy your beauty sleep . . . it's just past 5pm in New Zealand. I'll catch your tomorrow again

Re: Skype video not working - black screen

One Skype video solution I have seen involves making a shortcut with the command:
env LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype

[snowflake_nz]

Re: Skype video not working - black screen

Hi arochester

thanks for that, but I've actually already done that this afternoon. Right next to the K-menu I made a launcer for Skype with that command, so I've actually only got 1 mouse-click instead of 2 to get skype going.

[Detonate]

Re: Skype video not working - black screen

As you have it working, I'm going to just lurk now, maybe GG will have some further insight now that we finally found the device listing.

[snowflake_nz]

Re: Skype video not working - black screen

Love the lurking bit Detonate.

Thanks for all the help anyway. All help is welcome, doesn't matter if it's 100% it's workable, does what it should and that's more than I can ask for.

Bus 001 Device 004: ID 0402:5602 ALi Corp. M5602 Video Camera Controller

The ID 0402 identifies the maker
The ID 5602 identifies the model.

There is a module called gpsca_m5602.

$ modinfo gspca_m5602

jerry@sonyvgnfw140e:~$

Your lsmod command shows that gspca_main is used. I didn't see gspca_m5602 in your lsmod listing. Perhaps you could use
lsmod | grep gspca
agains and see if it is listed.
If not, do sudo rmmod gspca_main and then sudo modprobe gspca_m5602, which should automatically load gspca_main and then itself. Then, just try "skype" from a Konsole

The command
v4lctl -c /dev/video0 list
will show the various settings of the video device, IF you have v4lctl installed.

The "sensor" setting is probably either 1 or 6 (no default is shown). So a modprobe like this:
sudo modprob gspca_m5602 sensor=1
will force a sensor setting. If that doesn't work use rmmod to remove both modules and redo the command with sensor=6.

IF you want the menu option to work you can put
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype
in the command text box for the Skype menu option. (right mouse on Kgear and chose "menu edit".)

Either way, you say your little script works with one click. If you are happy with it, keep it!

Re: Skype video not working - black screen

Hi there GG

thanks anyway. The problem isn't solved per se, but I'm going to thank you and Detonate from the bottom of my heart.
I'm going to stick to my little script - don't know why I didn't think of it in the beginning. But then again, it's always lovely to go through something like this because I learn something new too.

I'm going to mark this thread as solved and just edit my first post with an explanation of what I did.

Thank you so much.
See you around
Tanya
