2goPC Web Camera Setup

[Hacao]

after installing the xawtv3.95.pet, I got a missing library notices. The missing libraries are:
libFS.so.6, libXxf86dga.so.8 and libXaw.so.8

I just updated XawTV for Puppy4 here -

WOW ! working ! (Puppy 2.16, Hacao Linux)

Thanks,

Thank you. tempestuous for updating the xawtv.pet. I glad that Hacao did get xawtv to show the video from the web camera. I tried and got this message from stderr device:

ioctl: VideoC_STD (followed by a long list of video standards)
Xliv: extension "GLX" missing on display ":0.0"
Station "0" not found
can't grab display

For my purposes, videoview and ffmpeg are sufficient for using the web camera. I will take a look at using mplayer. It is a standard package for Puppy 4.0 and should be used. Off to look at the mplayer documentation.

Hello Greg,

Thank you for this post! It saved me a day's worth of recompiling puppy 4.0 to get my objectives done.

My webcam QuickCam Fussion Logicool (from logitech) is working!
Im happy!!!

However, after 10 seconds of skype with video, half down of my video is stuck and only half up of my video is working. I can fix it by stoping and starting the video, but it will only last average for 20 seconds... is there any other parameter that I should add for starting the video ?

Please advise
Thanks a bunch!

reginr,

I'm sorry, I do not have any experience with Skype. From the what you have said, it appears the web camera is working since the up link video is working. There maybe a Skype problem. My guess is there maybe a memory allocation problem for the down link video. If the down link video is stopping, may be the memory for the downlink is not being re-used properly. I am guessing at this point.

I would suggest that you post your problem in the user forum as Skype problem. Forum members with more experience using Skype may be able to help you.

I hope this helps.

I followed the instructions and got as far as this - no such device. Could not find video grab device.
I am trying to set up a Logitech Quickcam (not sure of the exact model, there's nothing written on it).

I'm on Puppy 4.0 ... and I know sound and video are working because I can play DVDs.

PuppyMess,

This "how to" is for the Vmicro web camera in the CTL 2goPC. The Logitech QuickCam may require different settings. Is the Quickcam a USB device? If it is then here are two ideas that may help.

First, idea, is to try /dev/video0 in place of /dev/video.
The second idea is to use the trace parameter of uvcvideo. The following needs to be done in a console window (Console icon on desktop). One first has to remove the module:

Code: Select all

rmmod uvcvideo

Then one has to re-install the module with trace set

Code: Select all

modprobe uvcvideo -trace 15

One can see the output by using:

Code: Select all

dmesg | more

Hit the space bar to page down through the text output. One should see uvcvideo reporting if it found the camera.

The above does not help then use the forum search function for Quickcam, someone else may have posted information on its operation. I did a search and found these two that may help:

From reading, the posts, one should use

Code: Select all

lsmod

to see what modules are loaded.

I wouldn't assume that the uvcvideo driver discussed in this thread is compatible with your webcam.
You may need the "gspca" driver from here
http://www.murga-linux.com/puppy/viewto ... 302#148302
or the "qc-usb/messenger" drivers from here
http://www.murga-linux.com/puppy/viewto ... 88&t=23456

A good start would be to determine the device id of your webcam. Plug in your webcam, then do this -

Code: Select all

cat /proc/bus/usb/devices
