I'm not a developer on this, I'm the project manager. We use the commercial Macromedia tools to compile the fla to swf.

The anal retentive side of me likes to double check things as I approach a release to verify that everything that changes is something that I expect to change. In this case I was surprised to find a change that I was not expecting. I was able to find the swftools and use swfdump --hex to get a dump of the uncompressed swf tags and observed that the MX4 tag is the only changed portion of the swf.

At this point, I'm relatively comfortable that I don't need to worry about the differences. But I'm still curious what the MX4 tag represents.

how you can compile from .fla with swfc ?

Dwight Shih a écrit :

I'm trying to understand why two swf files compiled from the same fla (at different times) are different. When I compare the results of swfdump --hex for the two files, the difference appears to be the MX4 tag and the associated tag data.

What information is contained in this tag?

Thank you,
