I would like to ask you to recommend me a C/C++ library to capture video.
I am getting frames from a camera at 16 bits per pixel (RGB), and I would like to save those frames in a video format in an efficient way to be able to look at it in the future.
Would you please recommend me a good C/C++ library that I can use under Linux please?
A Google search gives me a lot of libraries, and I am really not sure which one does a good job and is widely used. I would greatly appreciate your help.
Thank you very much.
As far as I know -- the predominat library is Video4Linux -- however I have not tried it myself, but the list of applications using/supporting it is impressive.
Addition:
For Multi media Encoding GStreamer is probably one of the most used frameworks.

Hello i haven't been using EAGLE for a while now and had mostly forgot where to get any good and complete library of basic parts like resistors, LEDs, transistors... I have tried to find a library i need on EAGLE web page, but i haven't found any, that would offer quite large amount of basic parts.
If anyone could point me to a library with a good and large set of basic parts he would really save my day.
The Sparkfun Eagle libraries are quite good. Download at https://github.com/sparkfun/SparkFun-Eagle-Libraries
dear you can use "ORCAD" software rather than using EAGLE as it is easy in use and easy availability of its libraries on net.

I need to add some mp3 file playing functionality to my Linux based embedded application. Until now I used a system call (mpg123 -qm list of mp3 files). But now I don't have all the elements of the playlist, but get the next one only when I'm ready with the previous one. With mpg123 it means that I have some stupid noise between the tracks, as I always have to restart the mpg123 binary.
I was looking around for some libraries and found libmad, lame, sdl and co. But they seem to be a bit overcomplicated at first to handle. I found the fmod (http://www.fmod.org/index.php/download) library easy to use. But it's available only in binary format, which doesn't fit my ARM-based target (not to mention the licensing problems). Does anybody know about any similar, open source library capable of playing mp3 files similar to fmod?
mpg123 has an API, perhaps you could use that instead of calling the binary?
OK, finally with the help of houbysoft's hint i found a solution which uses libmpg123 and libao, here, and with some tuning i managed to get pretty smooth file-by-file playing. Thx for the hint!

I want to determine which part of audio file contain speech or music.
I hope someone has a made something like this or can tell me where to start.
Can you please suggest some method/tutorial for doing the same.
Thank you.
Check out the pyAudioAnalysis python library. Among others, it has a pre-trained speech-music classifier and two segmentation-classification methods (one based on fix-sized windows and another based on HMMs).
You can extract speech and music parts of an audio recording quite easily, e.g.:
from pyAudioAnalysis import audioSegmentation as aS
[flagsInd, classesAll, acc] = aS.mtFileClassification("data/scottish.wav", "data/svmSM", "svm", True, 'data/scottish.segments')
with a result as the one in this image
There's lots of prior art in this area, but I'd suggest browsing through some of Dan Ellis's papers. The slides for this talk has some good background. In short it's all down to picking the right feature vectors.

I've noticed that the wiki transcriptions for some of the recent Stack Overflow Podcasts are kind of weak. Clearly, this task calls for a computer program. Is transcribing audio to text (ideally with speaker labels so we know who said what) something that could feasibly be accomplished in software? Are there any active open-source software projects attempting to implement such functionality?
Believe me, I have searched for this before. There are slim to none text to speech that are open source or free to use. From my search there weren't any free speech to text synthesizers. These things are so hard to code and expensive that they can't really be made with an open source approach. If you really need this you would have to purchase it from a company. (although I don't know any off the top of my head).
I've looked into this a little. I tried the Microsoft Speech API but got very poor results. I've been wanting to look into the CMU Sphinx project, especially the Transcriber demo.

Do you remember those Magic Eye images that contain a 3D object? I love them!
Are there any open source programs for generating Magic Eye pictures, which ideally work on Linux.
I found a Gimp plugin, but haven't managed to get it working yet.
There's a package in Ubuntu for a program called Stereograph. It's website is here:
http://stereograph.sourceforge.net/index.html
Here's a tutorial on how to make them using GIMP, Blender and Stereograph:
http://linuxgazette.net/104/kapil.html
It's pretty basic, but you should try openstereogram, it's OS independent:
http://code.google.com/p/openstereogram/
There's also this JavaScript app:
