Current Firefox, Opera and Chrome have WebRTC build in (no plugin) that does that. You need to arrange a meeting point (like this https://apprtc.appspot.com ) with a common identifier (e.G. on apprtc you get redirected to an individual url and must pass this url to your chat partner) and can start chatting instantly.
WebRTC is the framework below the ...
TightVNC is a cross-platform (Linux and Windows) open source implementation of the VNC protocol. There are many other VNC clients and servers, most should work with each other without problem. Most Linux distributions have some VNC server/client built in, so does OS X (called Screen sharing).
Jitsi is a solid option. It's free and licensed under LGPL. It's Java based so it will run on Windows, Linux, and Macs. It supports a number of different protocols as well. It offers both audio and video chat with encryption.
Recently due to all the "NSA is dropping eaves everywhere" ruckus I came across a reddit or Ycombinator post that mentioned a free, secure, open-source alternative to skype called Tox (http://tox.im/). From their website, they say that "Tox is built on a 'privacy goes first' agenda" so this is good. It's open source too.
I installed Tox, ...
As you haven't specified that you want the software to be Open Source (Free), or Premium, I would assume that you are opened to both as Camtasia is Premium.

Linphone here springs to mind: https://www.linphone.org/
I've not used this for many years, but I'm aware it has an Android app (and works with Windows, iOS and Mac). It's released under the GPL so it's free and open source. You can use your own SIP or sign up for a free account on the Linphone website. It will interact with any SIP protocol I believe, but ...
AwesomeTalk does this. From my experience with it, it works very well, the video and audio quality is clear and I've noticed little to no stuttering or lag. It's just as you ask, nothing fancy, just straight 1 to 1 video chat. Works on all major browsers and even has a chrome extension.
Disposable private urls

Another reason to switch away from Skype is that they are owned by Microsoft and have been shown by the Snowden leaks simply to give data from Skype conversations to the NSA, including recorded calls.
For an excellent and more private alternative to Skype try Jitsi Meet. It is open source, conversations are end-to-end encrypted (not like Skype) and it is ...
You can try Ekiga. It's an open-source SoftPhone, video conferencing and instant messenger software. It runs on windows and linux. I believe you can host with it, but I've never done it. It should be explained in the Manual.
To make it always on top with windows, I use AutoHotkey. There are some good explanations in this HowToGeek article.

no closed-source 3rd party parts: Not as far as I can tell

Various plans including free which is limited to 3 total participants, i.e. 3 ...

sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"
