Tag Info
Tag Number: 
Tag Type: 
Tag Flash Version: 
Unknown SWF Tag: 
This tag is not known (not defined by the Flash documentation by Adobe)
Brief Description: 

This tag defines information about the product used to generate the animation. The product identifier should be unique among all the products. The info includes a product identifier, a product edition, a major and minor version, a build number and the date of compilation. All of this information is all about the generator, not the output movie.

Tag Structure: 
struct swf_metadata {
	swf_tag			f_tag;		/* 41 */
	long			f_product_id;
	long			f_edition;
	unsigned char		f_major_version;
	unsigned char		f_minor_version;
	long long		f_build_number;
	long long		f_compilation_date;

The ProductInfo tag stores information about the tool used to generate the Flash animation. This is ignored by flash players (unless it knows of problems in the generators...)

The f_product_id is expected to be a unique identifier for all the products which can possibly generate an SWF output file.

The f_edition represents an edition of the generator. For instance, you may have a free version, and three commercial versions (Standard, Pro and Deluxe) which all should have a different edition number. Yet, the product is the same.

The f_major_version and f_minor_version are used to define the generator version used to create the SWF animation. Note that these numbers are limited to a value between 0 and 255.

The f_build_number is usually a MS-Windows build number. This does not really apply to Unix versions. Under Unix, one can use this number to extend the version to additional digits (i.e. SSWF saves 1.8.1 in the build number.)

The f_compilation_date represents the date and time when the generator was compiled (not the time when the output movie is generated!)
