There\'s plenty of them out there but none of them do what I would like them to do.
Most of them crash when opening a file or simply corrupt the data. Many don\'t run at
Flash originally serialized data into a format called AMF, and with version 9+ uses an updated version called AMF3. While the AMF specs are open (the AMF3 spec is here), I don't think Adobe has opened the format of SOL files themselves. (Also, I think that SOL files written partially by v9+ players may contain both AMF0 and AMF3 data.)
As for existing apps/frameworks, it looks like PyAMF is your best bet, as it's the only one I found after a quick browse that claims to grok both AMF0 and AMF3. I haven't personally used it however.
