Skype has forced most people to upgrade to the latest version so this is not a problem for most people, however, if you are running the latest version (which is currently 6.4.59.833) you may have problems with anyone using a version earlier than 5.0. If you are talking to someone who is using a previous version of Skype earlier than version 4.2, and you have a later version, video calling will not work (as far as I can tell).
As usual I turned to the internet for help, but in the end I managed to solve it myself with a few pointers to the reasons causing the problems. I really didn‘ t understand what was going wrong.
So my problem was that, although I had previously tested my built-in Macbook camera was working (but not running in the background) and I could even see myself under the Audio/ Video tab in Skype Preferences, every time I pressed the video call button it tried it s best to switch to video and then reverted back to voice call. If you aren‘ t sure how to make a video call on the new Skype (version 6) please read the walk through on the Skype website here. This is just a quick post about some problems I had with video calling on Skype recently.
