I need to create a script to read in an uncompressed video file, sample a frame every 1/2 second, and output a bitmap. I would need to do this in Ruby.
I am having an issue starting out. Is there a package that I can use to handle the metadata in the video file? Any suggestions on what format video file I should use?

I use ffmpeg pretty much all the time when working with video data, so if you have access to it then you can try any of the ruby interfaces available such as streamio-ffmpeg
If you're unable to find a ruby gem that is compatible with your environment, and you must (or prefer to) use Ruby, then you may consider making system calls directly depending on your needs.

I'm using LoadRunner but I do not wish to use the Analysis tool of LoadRunner to do the results analysis.
I've found out that the results are stored in the *.eve.gzl files (in the Result folder), but the *.eve files doesn't seem to be readable even after unzipping *.eve.gzl via 7-zip.
What format are *.eve files based on?
You cannot read the eve files as this is a proprietary format. Actually there are many more files that need to be read in order to decipher the eve files. What you can do is to open a new session with your results in Analysis tool that comes with LoadRunner. It will create a database file for you from the eve files based on the database you configured in the tool. You can then try to use this database to do your own analysis.

Due to the various issues with getting hsSDL to work on Windows, I'm looking for another library that can handle keyboard input and drawing images to the screen. Does anyone know of any?
I've successfully used gloss on Windows in the past without issues. It's also very simple (which I like) and is my go-to recommendation for people who want to use Haskell for simple graphics/ basic games.
Edit: It looks like gloss is having issues building on the Hackage server and as a result isn't displaying documentation. Here is the documentation for version 1.8.1.2, which should be about the same.

I am looking for a simple video annotation tool that contains the following future:
Create rectangles around objects in various frames and the tool allows to export these information (frame#, rect1.xy, etc...) into a txt file/excel file etc...
I have been searching the whole web today but could not find one solution. I only found vatic, but there you have to pay for Amazon's Mechanical Turk:

Anybody knows some tools that do the same thing?
You can still continue to use VATIC in offline mode without paying for Amazon's Mechanical Turk services.

Expect seems to be a very powerful automation tool: http://www.nist.gov/mel/msid/expect.cfm
Is there a Ruby equivalent to that tool?
There's the pty package in the standard library, but that only implements a subset of the functionality of the Tcl package. In particular, it appears to lack the ability to wait for many patterns at once, or to provide interaction at the same time. Maybe this won't matter for what you're doing with it; a great many expect programs never make use of its full power.
