Thanks micheal....Yes i can use xawtv program...but its very confusing....i already learned the "c" programming....now i have to understand what is "v4l2 program does....Thats why i asked you...i saw all the programs in xawtv...including "streamer.cand capture.c"...but there is nommap()function there...Thats why i asked first....can you help me to capture video in your application which you sent me...?Thanks for your valuable reply.....
I would describe V4L and V4L2 as software in the Linux kernel that helps to use cameras with Linux. They provide a common programming interface for different kinds of cameras.
To capture video using the program "vgrab.c", it needs to be modified to continuously capture and display pictures, instead of storing a single picture as a file. One way to display the captured pictures is with the library called 'SDL'. Can you determine if it is installed on your computer? If it is not, can you install it? (A google search for SDL will find the website to download it.)
Another possibility for displaying pictures is with the 'X11' library, but it is more complicated.
