according to Page 59 of
http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v10.pdf
The FileAttributes tag defines characteristics of the SWF file. This
tag is required for SWF 8
and later and must be the first tag in the SWF file. Additionally, the
FileAttributes tag can
optionally be included in all SWF file versions.
but in rfxswf.c:
int WriteExtraTags(SWF*swf, writer_t*writer)
{
...
if(swf->fileVersion >= 9) {
...//write FileAttributes and other tags.
}
...
}
btw, there is a flag in rfxswf.c
int no_extra_tags = 0;
but no where to change it
