<\/p>\nI was asked to look for open source tools to read the basic information contained in a Flash swf file. Most of the items you find are for reverse engineering swf files. In the search process I found two sources to parse the swf file header. <\/p>\n
The first was a php script<\/a> written by Carlos Falo Herv\u00e1. You need to scroll down to the end of the post to find his work. This works just fine if you want to run off a server. <\/p>\n The second is written in Actionscript<\/a> for Flash CS5. Only the author’s handle, jared, and not the author’s name is not available at the site. The download works nice and you can run from the author’s web page. You need type or paste in a url for the swf file name. The code is all dropped in on the first frame.<\/p>\n This site also provided a nice link to the Adobe SWF file version 10 specifications<\/a> if you care to know. Page 25 has the key information on the SWF header. This is also repeated in the SWFHeaderParser parser class presented in this post.<\/p>\n I took the code for the second example and created a drag and drop version Adobe Air. First I separated the code into two Actionscript classes. One for parsing and one for loading swf file bytes. These classes are named respectively SWFHeaderParser and SWFHeaderLoader. I added a value object, SWFHeader_vo, to pass around the values. <\/p>\n I glued those items together in an Air project using the Parsley framework. This gave me a chance to use Parsley DynamicObject for the SWFHeaderLoader class that loads the SWF file for the parser.<\/p>\n The result is a fully decoupled version that serves as a super example of model-view-controller using Parsley for an Air app.<\/p>\n Download files: [ad name=”Google Adsense”]<\/p>\n SWF Parser – SWFHeaderParser.as<\/strong> SWF Loader – SWFHeaderLoader.as<\/strong> Most of this is standard URLLoader coding. <\/p>\n The SWFHeaderParser is called on line 62. On line 63, the actual bytes are not gotten from the SWFHeaderParser. So it can be a bit misleading that that is information found in the SWF header. The SWF header only contains the uncompressed file size.<\/p>\n SWF Header Value Object – SWFHeader_vo.as<\/strong> [ad name=”Google Adsense”] Application Class – SWFHeader.mxml<\/strong><\/p>\n This is the application mxml file. Gotta love how Parsley helps make these application mxml files minimal.<\/p>\n Parsley Configuration File – ParsleyConfiguration.mxml<\/strong> Air Application Descriptor File – SWFHeader-app.xml<\/strong> Main.mxml<\/strong> SWFHeaderBasic.mxml<\/strong> ApplicationCloseButton.as<\/strong> ApplicationCloseButtonSkin.mxml<\/strong> ApplicationModel.as<\/strong> [ad name=”Google Adsense”] ApplicationController.as<\/strong> LoadSwfUrlHeaderRequestEvent.as<\/strong> SWFHeaderLoaderProgressEvent.as<\/strong> SWFHeaderLoaderCompleteEvent.as<\/strong> SWFHeaderLoaderErrorEvent.as<\/strong> I was asked to look for open source tools to read the basic information contained in a Flash swf file.

\nHere is the Flex project if you want to explore the code and the Air installer in case you just want the tool.<\/p>\n\n
\nThe parser class is first as that is what you might want to integrate into your code. Note it returns the SWFHeader_vo class. The comments are scant in this class since I did write the code and only converted it into a class, returned a value object and removed code not specific to parsing the bytes. The value object is created and populated on lines 85 – 95.<\/p>\n\r\npackage swf\r\n{\r\n\timport flash.geom.Rectangle;\r\n\timport flash.utils.ByteArray;\r\n\timport flash.utils.Endian;\r\n\timport vo.SWFHeader_vo;\r\n\t\/**\r\n\t * SWF Header parsing.

An FWS signature indicates an uncompressed SWF file; CWS indicates that the entire file after the first 8 bytes (that is, after the FileLength field) was compressed by using the ZLIB open standard. The data format that the ZLIB library uses is described by Request for Comments (RFCs) documents 1950 to 1952. CWS file compression is permitted in SWF 6 or later only.\r\n\t\t\t\r\n\t\t\tA one-byte version number follows the signature. \r\n\t\t\tThe version number is not an ASCII character, \r\n\t\t\tbut an 8-bit number. For example, for SWF 4, the version byte is 0\u00d704, not the \r\n\t\t\tASCII character \u201c4? (0\u00d734). The FileLength field is the total length of the \r\n\t\t\tSWF file, including the header. If this is an uncompressed SWF file (FWS signature), \r\n\t\t\tthe FileLength field should exactly match the file size. If this is a compressed SWF file \r\n\t\t\t(CWS signature), the FileLength field indicates the total length of the file after decompression, \r\n\t\t\tand thus generally does not match the file size. Having the uncompressed size available can make \r\n\t\t\tthe decompression process more efficient. The FrameSize field defines the width and height \r\n\t\t\tof the on-screen display. This field is stored as a RECT structure, meaning that its size \r\n\t\t\tmay vary according to the number of bits needed to encode the coordinates. The FrameSize \r\n\t\t\tRECT always has Xmin and Ymin value of 0; the Xmax and Ymax members define the width and \r\n\t\t\theight. The FrameRate is the desired playback rate in frames per second.\r\n\t\t\t\r\n\t\t\tSource: http:\/\/simplistika.com\/parsing-reading-swf-header\/\r\n\t\t\t\r\n\t\t\t*\/\r\n\t\t\tvar vFormat : String;\r\n\t\t\tvar vSwfVersion : int;\r\n\t\t\tvar vFileLength : int;\r\n\t\t\tvar vFrameRate : int;\r\n\t\t\tvar vTotalFrames : int;\r\n\t\t\tvar vFrameSize : Rectangle;\r\n\t\t\tv.endian = Endian.LITTLE_ENDIAN;\r\n\t\t\tvFormat = v.readUTFBytes(3);\r\n\t\t\tvSwfVersion = v.readByte();\r\n\t\t\tvFileLength = v.readUnsignedInt();\r\n\t\t\tv.readBytes(v);\r\n\t\t\tv.length -= 8;\r\n\t\t\tif (vFormat == "CWS")\r\n\t\t\t\tv.uncompress();\r\n\t\t\tv.position = 0;\r\n\t\t\tvFrameSize = new Rectangle();\r\n\t\t\tvFrameSize.left = xfReadNBits(v, true) \/ 20;\r\n\t\t\tvFrameSize.right = xfReadNBits(v) \/ 20;\r\n\t\t\tvFrameSize.top = xfReadNBits(v) \/ 20;\r\n\t\t\tvFrameSize.bottom = xfReadNBits(v) \/ 20;\r\n\t\t\tvFrameRate = v.readUnsignedByte() \/ 256 + v.readUnsignedByte();\r\n\t\t\tvTotalFrames = v.readUnsignedShort();\r\n\t\t\tvar swfHeader_vo:SWFHeader_vo = new SWFHeader_vo();\r\n\t\t\tswfHeader_vo.format = vFormat;\r\n\t\t\tswfHeader_vo.swfVersion = vSwfVersion;\r\n\t\t\tswfHeader_vo.sizeUncompressed = vFileLength;\r\n\t\t\tswfHeader_vo.width = vFrameSize.width;\r\n\t\t\tswfHeader_vo.height =vFrameSize.height;\r\n\t\t\tswfHeader_vo.frameRate = vFrameRate;\r\n\t\t\tswfHeader_vo.totalFrames = vTotalFrames;\r\n\t\t\treturn swfHeader_vo;\r\n\t\t}\r\n\t\t\/**\r\n\t\t * Original code from http:\/\/simplistika.com\/parsing-reading-swf-header\/.\r\n\t\t * *\/\r\n\t\tprivate function xfReadNBits(v : ByteArray, vStart : Boolean = false) : uint\r\n\t\t{\r\n\t\t\tvar n : uint;\r\n\t\t\tif (vStart)\r\n\t\t\t{\r\n\t\t\t\txByte = v.readUnsignedByte();\r\n\t\t\t\txNBits = xByte >> 3;\r\n\t\t\t\txOffset = 3;\r\n\t\t\t}\r\n\t\t\tn = xByte << (32 - xOffset) >> (32 - xNBits);\r\n\t\t\txOffset -= xNBits;\r\n\t\t\twhile (xOffset < 0)\r\n\t\t\t{\r\n\t\t\t\txByte = v.readUnsignedByte();\r\n\t\t\t\tn |= (xOffset < -8) ?
