i used to create a tutorial video with camtasia studio, but curious to know if opensource have application that provide abilities like camtasia studio have
such as
- keep track action happen during recording. can produce video that zoom to part i want.
- Display the text of screencast as an overlay or below the video.
- With just one click, video is on its way to YouTube .
After searching a bit online, here's what I come up with: http://camstudio.org/
It can create video recordings off your screen, and generate swf's to easily inject them into websites.
It's able to add nice, anti-aliased screen captions to the video, and even supports picture-in-picture video (screen caption + video of you through the webcam)
You can record the whole screen, or just a portion of it.. I'm not sure if it supports zooming-in to sub areas while live recoding, but even if it doesn't - it's easy to emulate this using Windows 7 zoom (or if you don't use Win7 with tools like ZoomIt from Sysinternals
It comes with it's own free codec as well.
It's all 100% free, open source and licensed under GPL, woo!! :D
P.S. I'm in no way affiliated with them.. I just found it myself :)

I was just wondering if anyone knows whether it is possible to embed augmented reality into a website. So for instance, if I was to create a space invaders style game could I use put a placeholder image onto a website that comes to life and starts playing the game outside/around the computer when the users holds their phone up to the screen?
OR
Create a website designed to be accessed on your mobile. And then when the user access the website, it accesses (with their permission) the users camera to turn their environment into the space invaders game. Critically I don't want to force the user to download anything but I can't find anything to support whether this is possible or not.
Many thanks!
You can use WebGL+Vuforia for building Augmented Reality for a web page. For example like this.
Moreover, you can check this related medium post. It can be helpful for you. This project was developed by a Javascript framework for Augmented Reality.

one thing that annoys me on youtube is that it always starts playing the video automatically after opening the video page.
is there a way how to prevent it? i don't see such option in profile settings.
There plenty of greasemonkey scripts available to do this exact thing (search for 'autoplay'). Also, this belongs on Super User.
You can install the flashblock firefox extention. That will prevent anything flash from starting automatically. This works perfectly on youtube, and as a bonus it will get rid of a huge amount of annoying ads with blinking text or whatnot.

Just by messing around a little it seems that the video stream is not ascii. i tested by downloading the stream. It would be insane if it was. Theres so many videos. So that couldnt be it. Youtube seems to not work with javascript disable (not counting mobile if true).
How is it being done? is it javascript magic? is the SWF running the video through a filter in realtime? (I doubt its a native filter so how is the filter compiled) its really cool. I cant imagine how this is running realtime yet it is!
MPlayer uses AALib for this type of effect. YouTube have probably ported it to ActionScript.

I am a web developer well-versed in XHTML/CSS, JavaScript, Perl, PHP, and XML/XSL. I would like to write a desktop application for music teachers that manipulates audio files. The app will:
Input one or more audio files
Let the user pick in and out points of several clips
Play those clips at the touch of a button with fade-in and -out
Render those clips out to new audio files
The application must:
Run on Windows, Mac, and Linux without tons of extra coding for each
Have a nice GUI for totally non-tech-savvy people (i.e. professors)
I've never built a desktop application before, and am prepared to learn a new language. From what I've read, an Adobe AIR app built with ActionScript and Flex seems to be the most straightforward. I'm not thrilled about learning such a proprietary system, though. Does anyone have suggestions for a better approach, preferably open-source?
Or, is this possible using AJAX through AIR?
Thanks!!
Java would be the way to go if you're wanting to learn a new language that you can leverage for more than just this one time project.
Silverlight would be great if you could live without the Linux version.
I've used MP3DirectCut for similar purposes. I suggest you play with its features for skipping, looping, and marking before you settle on the design for your own application. I'm also reminded MP3DC saves your project, so you can open it again and all the selections are there. You will probably want something similar in your app.
As for language, I'd first find a suitable open source audio project to base off (Audacity comes to mind), then write in whatever the natives speak, or something that had good bindings to that language.

I've been asked to come up with options to offer free ringtone downloads on a website. These would be actual free ringtone downloads, not "Sure, we've got free ringtones, but wouldn't you rather have these much cooler ringtones over here for $1.99?", but actual free-to-download ringtones. Is there a way to provide this in a relatively global manner? Is it as simple as providing a low-quality, 30-second MP3 that the user can convert themselves? Is there a service out there that provides this functionality? We're looking for options. Thanks.
There's different methods of starting downloads based on which carrier/phone you're using
Sprint - GCD(generic content descriptor)
Verizon you have to send an MMS
ATT - depends on the phone
Nokia phones need a DD(download descriptor)
The list goes on and on and on
Not really a simple problem to solve
ringtones vary by phone; some require MIDI ringtone, for example, but for most modern phones a direct download of a short mp3 file is sufficient
