Question about opening files in the beagle bone

I was following this tutorial and I was wondering on where exactly files are stored inside the BeagleBone. Also, is there a way to access them?

Hi @mochafish looking in the source…

"Example usage: capture -F -o -c 300 > output.raw\n"

github.com

derekmolloy/boneCV/blob/master/capture.c#L587

      
        
                             "-d | --device name   Video device name [%s]\n"
                             "-h | --help          Print this message\n"
                             "-m | --mmap          Use memory mapped buffers [default]\n"
                             "-r | --read          Use read() calls\n"
                             "-u | --userp         Use application allocated buffers\n"
                             "-o | --output        Outputs stream to stdout\n"
                             "-f | --format        Force format to 640x480 YUYV\n"
            		 "-F | --formatH264    Force format to 1920x1080 H264\n"
                             "-c | --count         Number of frames to grab [%i] - use 0 for infinite\n"
                             "\n"
            		 "Example usage: capture -F -o -c 300 > output.raw\n"
            		 "Captures 300 frames of H264 at 1920x1080 - use raw2mpg4 script to convert to mpg4\n",
                             argv[0], dev_name, frame_count);
            }
            
            
static const char short_options[] = "d:hmruofFc:";
            
            
static const struct option
            long_options[] = {
                    { "device", required_argument, NULL, 'd' },
                    { "help",   no_argument,       NULL, 'h' },

“capture” outputs the file where you want it…
