Video::Info::FOO.3pm

NAME

Video::Info::FOO - what is it useful for? an example list:

  -video codec
  -audio codec
  -frame height
  -frame width
  -frame count
 
 

and more!

SYNOPSIS

   use Video::Info::FOO;
 
   my $video;
 
   $video->vcodec;                         #video codec
   $video->acodec;                         #audio codec
   ...
 
 

DESCRIPTION

What does the module do? What are it's limitations? Is it built on top of other code? If so, what are the details and where can I get it?

METHODS

Video::Info::FOO has one constructor, new(). It is called as:
  -file       => $filename,   #your RIFF file
  -headersize => $headersize  #optional RIFF header size to parse Returns a Video::Info::FOO object if the file was opened successfully.

The Video::Info::FOO object to parses the file by method probe(). This does a series of sysread()s on the file to figure out what the properties are.

Now, call one (or more) of these methods to get the low-down on your file:

BUGS

Audio codec name mapping is incomplete. If you know the name that corresponds to an audio codec ID that I don't, tell the Video::Info::Magic author, Allen Day <allenday@ucla.edu>.
