et le details
----
Here are some of the things added, changed, or corrected:
* new DefineBitsJPEG4 tag (90), with deblocking filter
* new DefineFont4 tag (91)
* described how to embed Speex into SWF and FLV
* described how to embed XMP metadata in FLV
* new flags in the FileAttributes tag describe whether a SWF
requires the new 'gpu' or 'direct' WMODEs (only useful when running a
SWF in a standalone player where there is no encompassing HTML to
specify WMODE)
* new flag in DefineShape4 describes whether the shape uses fill
winding rule
* rearranged some chapters to (hopefully) make the SWF spec flow
better
* revised DefineBitsJPEG2 and DefineBitsJPEG3 to mention how they
can be used to store GIF and PNG data as well as JPEG (as can the new
DefineBitsJPEG4 tag; yes, the tag names are a bit misleading, but
they're a bit too entrenched to be changed now)
* revised description of the Flash Screen Video v2 codec format
* in F4V, several signed values were incorrectly marked as
unsigned
* fixed description of Flash ADPCM (initial predictors are signed,
not unsigned; block size was off by 1)
* both documents now thoroughly describe which parameters
(channels, bit resolution, sample rate) are fixed or flexible
depending on the audio codec
* the FileAttributes tag came about in SWF 8 rather than SWF 1
* fixed the FileAttributes tag, which specifies a Metadata data
structure -- not a SymbolClass -- with the hasMetadata flag
* in ButtonRecord and PlaceObject3, list the correct codes for the
difference, add, and subtract blend modes
* PlaceObject3 tag description was missing a bitmap caching byte
(should have been there since SWF 8 spec)
* in FillStyle, a GradientMatrix is also present for fill style
0x13
* SWF spec now uses "opacity" instead of "transparency" in many
places in order to more accurately describe blending behavior
* clarified the maximum length of a SWF file
* fixed several examples
* fixed numerous inconsistencies in the Actions chapter
