Skype Beta 2.2.0.25 for Linux – Webcam WORKING!

Skype for LinuxUgh – finally, after much backward and forward (even to the point I dragged out a Windows laptop) I’ve tracked down the issue which was stopping my embedded webcams (which otherwise works in all other applications) from working with the latest beta of Skype for Linux.

The solution is this (thanks Ubuntu Forums):

for 32-bit Linux / Skype

sudo mv /usr/bin/skype /usr/bin/skype.original
sudo echo -e "#!/bin/bash \nLD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype.original" > /usr/bin/skype

for 64-bit  Linux / Skype

sudo mv /usr/bin/skype /usr/bin/skype.original
sudo echo -e "#!/bin/bash \nLD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype.original" > /usr/bin/skype

I found the command to build the script didn’t work out for me

$ sudo echo -e "#!/bin/bash \nLD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype.original" > /usr/bin/skype
bash: !/bin/bash: event not found

So, I built my own script

sudo nano /usr/bin/skype

and pasted in the lines to build the script

#!/bin/bash
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype.original

Of course, the script needs to be made executable

sudo chmod +x /usr/bin/skype

Then all that remained was to make sure no instances of skype were running, and re-launch skype from the menu.

For me, the video came up once Skype had loaded, from other discussions, some people may need to restart their machines.

Chrysalis Cam – Using Open Source to Open Minds

The kids in Room 3 had a problem, all of the caterpillars that went into the pupa stage of their metamorphosis were emerging when the students were out of the classroom.

The solution was to setup a laptop with a web camera programmed to take a snapshot of a waiting chrysalis once every minute. These images were stitched together into a time-lapse which captured the butterfly emerging in this video.

Feel free to skip over rest of the content in this article as what is of interest will vary greatly between viewers – but I wanted to present the whole story in one location in case it is useful to others who are studying similar processes.

The Lesson

Before getting into the detail of the ‘how’ the project was done, it was fascinating to watch the kids go through the journey of:

  • Identifying the problem of missing the butterflies emerging
  • Strategising what they could do to overcome the issue
  • Discarding ideas which were unworkable
  • Agreeing on using the computer / webcam
  • Thinking about what other things time-lapse would be useful for

Viewing multiple video streams using Linksys WVC54G

We’ve got a couple of Linksys WVC54G IP cameras lying around the office from a previous project, so I was thinking “How hard would it be to create a page I could navigate to from my home PC (or media center) to view live video streams from these cameras?”
Apparently, it’s a bit harder than one would think…
