In 2008, the specifications document was criticized by [[Rob Savoye]], the lead developer of the [[Gnash (software)|Gnash]] project, as missing "huge amounts" of information needed to completely implement SWF, omitting specifications for [[Real Time Messaging Protocol|RTMP]] and [[Sorenson codec|Sorenson Spark]].<ref name="stillpartlyclosed" /> The [[Real Time Messaging Protocol|RTMP]] specification<ref>{{cite web|url=https://www.adobe.com/devnet/rtmp/|title=Real-Time Messaging Protocol (RTMP) specification - Adobe Developer Connection|website=www.adobe.com}}</ref> was released publicly in June 2009.{{citation needed|date=August 2014}} The Sorenson Spark codec is not Adobe's property.
