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.

So I have an encrypted text I need to decrypt, where do I start and is there a program that automatically recognizes an algorithm ? Here is a snippet of what I need decrypted:

Encrypted text is designed to resemble random numbers. Cryptographic algorithms are designed specifically to keep you from doing exactly what you are trying to do.

I'm trying to implement a gray code counter using a shift register and a 4-1 MUX. Does anyone have an idea what logic to use?!
Thanks
I am not sure if this satisfies your requirement of "using a shift register and a 4-1 MUX", but here is a small and functional gray counter reference design by Altera:

I'm planning to do a handwriting recognition application for WP7 in next graduating report. The only time its left more than a month not enought to study from the beginning. I plan to use SVM, but also don't know much about it. If some one has done this, please guide me. Thank you so much !

Like the 20Q, is there a published algorithm that allows a program to "learn" from user input?
Programs like junk mail filters learn from what you tell it and uses that information to make more insightful choices in the future when classifying an email as junk.

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.
