I have a bunch of png images that I want to feed through ffmpeg to create a animation.
Anybody have some guidelines or ideas as to how I can achieve this?
See the FFmpeg FAQ: How do I encode single pictures into movies? Note that your images must be in sequential order starting with 1 such as image0001.jpg. Alternatively, you can use cat to feed non-numbered images to FFmpeg. See Converting hundreds of pictures of naming style “frame_0000.jpg”, “frame_0001.jpg” into an avi? for an example.

Well, in my application, you can select an image and put it in the form using opendialog. The problem is that the image won't be loaded, unless it's bitmap. So what do you suggest me to do?
Delphi 7 only supports bmp and jpg out of the box. To get wider image support you need to use a third party library. I recommend Mike Lischke's GraphicEx: http://www.delphi-gems.com/index.php/libs/graphicex-library
Based on the comments from the Andreas Rejbrand answers, I believe you should install the TGIFImage component. It supports Delphi7 and newer versions of Delphi.
Include the unit GifImage.pas to your project path from gifimaged2010b.zip, and add to your uses list. This will automatically add GIF in filters for openpicturedialog.

Is it possible to store multiple small images or icons as parts of a single image, so that my webpage can get all the icons it needs from a single GET request. This would help my page load faster.
This is an example of the sort of composite image I'm referring to:

It seems to me that it is some kind of array of images put into one file. I'm hoping there is some way that i can use each individual icon in the image in a project.
These are called sprite sheets, there's a great article about them on css-tricks that should help you understand how they work on the web.

I've been trying to implement video acceleration in libavg using VA-API video decoding with ffmpeg. They already have the VDPAU support for it. From their source code I understood that it has to do something with struct *vaapi_context and some functions - get_format, get_buffer, release_buffer - but I can't figure how to make that work.
It would be great if someone would be so nice to share simple notes how to set up and use functions to get avcodec_decode_video done with vaapi.

What I am doing as a part of my project is comparing and analysing all the noise removal and reduction filters there are in matlab.
Not able to find a comprehensive list of filters that have been built for this very purpose.
Well adding to my question, I wanted a list that would help me understand all the basics of noise removal using filters in matlab.
I have found various links such as this, which proved helpful.

When you have the toolboxes installed, you can also just look at the table of contents in the "Help" browser. Gives a pretty good summary of the options.

How to hide the text in the picture using the least significant bit ?
It looks like you're not sure what you're asking. Perhaps go and research the general idea of steganography.
Short answer: don't.
Slightly longer answer: it's a very inefficient form of steganography, it won't work for JPEG images, and for GIF/PNG it'll basically make your image uncompressable.
If you need stega for anything else but curiosity or school assignments, research existing offerings.
The technique you're thinking of is called Steganography. Here's a good post which explains the technique. http://www.dreamincode.net/forums/topic/27950-steganography/
