NAME Video::FourCC::Info - Find information about codecs specified as Four Character Code $Id: README 6745 2009-04-29 16:35:29Z FREQUENCY@cpan.org $ DESCRIPTION In order for video players to detect the algorithm required to decode a given video file, a four-byte sequence called a Four Character Code is written somewhere in the header of the file. This ensures that the detected codec format is independent of the file extension, which may be incorrect due to human error or for some other reason. This is similar to the four-byte "magic number" used by the UNIX file(1) command to roughly determine a file format. Most applications seem to treat this as a case insensitive code. As a result, internally, your given FourCC's will be silently converted to uppercase. COMPATIBILITY This module was tested under Perl 5.10.0, using Debian Linux. However, because it's Pure Perl and doesn't do anything too obscure, it should be compatible with any version of Perl that supports its prerequisite modules. If you encounter any problems on a different version or architecture, please contact the maintainer. AUTHOR Jonathan Yu ACKNOWLEDGEMENTS * Thanks to Allen Day and Benjamin R.
