## This is a simple script to make the Linksys WVC54G Cam worth
## something, without resorting to cron silliness.
##
## It might also work with other ASF cam feeds, YMMV.
##
## It will capture a single JPEG image from the ASF stream
## and then direct it to the output buffer as if it were
## just another JPEG fetch from a camera with that capability.
##
## It requires mplayer to be installed, configured with the
## jpeg vo option (default on Ubuntu) and have mplayer in the
## path.  Also, the directory that is running the PHP script
## must be writable by the UID executing PHP, or you'll need
## to make sure the file gets written/read somewhere else.

## Exec the mplayer
## -- To see debug output:
## ---- change 'exec(' to 'system('
## ---- remove '-really-quiet'
exec("mplayer -really-quiet -vf scale -nosound -nolirc -nojoystick -prefer-ipv4 -nocache -user yourusernamehere -passwd yourpasswordhere -frames 1 -vo jpeg http://change.to.your.camIP/img/video.asf");

## This is the name of the file generated by the above command,
## including path
$captureFileName = './00000001.jpg';

## Now we'll open the file for reading, in binary mode
$fileHandle = fopen($captureFileName, 'rb');

## Now we'll send the appropriate HTTP headers indicating this
## is a jpeg stream
header("Content-Type: image/jpeg");
header("Content-Length: " . filesize($captureFileName));

## Lastly, we'll use the fpassthru function to dump the contents
## of the file to the output buffer and exit
fpassthru($fileHandle);
exit;
