Well, just to present some facts, ffmpeg's libavcodec just recently in 2008 bumped soname again. And 2008 saw the move of the headers, so there are actually rather fresh changes in ABI/API, and the three years before didn't look much different (Note: libpostproc and libswscale). Note that the sonames are in the range 49-52, which indicates many bumps in ffmpeg's history. Also about a year or two ago I tried to get an upstream release blessed, there were many folks on ffmpeg-devel that were interested, unsurprisingly mainly distribution packagers. One of the main reasons stated from the core developers was that they don't want to commit to an API/ABI due to a release. So if there is FUD it is being fueled from upstream. Anyway if ffmpeg has really stabilized in terms of API/ABI then we will never again read anything about repo foo's ffmpeg not carrying the sonames as needed by repo bar, so any "bad" reputation ffmpeg may have in terms of API/ABI will automatically fade away, and maybe there will be an ffmpeg release again someday. FWIW I'm not criticising ffmpeg's development quality, this is a great project and very vivid upstream. It only lacks in the downstream channels, e.g. offering releases for the various downstreams to base their projects upon leading to every second project to fork off a snapshot from ffmpeg. So actually my plead to anyone dissatisfied with the API/ABI stability or bad rumor of it and with enough knowledge on the matter: Please try to get onto ffmpeg-devel and become a release manager. Release early, release often is what ffmpeg lacks. -- Axel.Thimm at ATrpms.net
