type for linux is "video4linux2" input url is "/dev/video0". For windows
the input codec type is "vfwcap" and input url is "0". look at sample code

av_register_all();

//----------------------------------------------------------
pInfmt = av_find_input_format("vfwcap");
if( !pInfmt ){
fprintf(stderr,"Unknown input format:mjpeg\n");
return -1;
}
// Open video file
if(av_open_input_file(&pInFormatCtx, "0", pInfmt, 0, NULL)!=0)
return -1; // Couldn't open file
