QuoteFFmpeg 5.0 "Lorentz", a new major release, is now available! For this long-overdue release, a major effort underwent to remove the old encode/decode APIs and replace them with an N:M-based API, the entire libavresample library was removed, libswscale has a new, easier to use AVframe-based API, the Vulkan code was much improved, many new filters were added, including libplacebo integration, and finally, DoVi support was added, including tonemapping and remuxing. The default AAC encoder settings were also changed to improve quality.
QuoteFFmpeg has had a lot of API changes during its history, but the project is very careful about those deprecations and removals: we deprecate then we wait to allow the users time to upgrade, then we remove the APIs, because it could break the users programs.But lately a lot of the APIs marked as deprecated were kept. Worse, internally, some of those APIs were still used, because it has been 4 years since we last removed anything.So, in FFmpeg 5.0, a huge patchset removing all those deprecated APIs was merged last April. You can see that the patchset is more than 80 commits of removal Some APIs were deprecated since 2013 and the changes can appear huge. But it's a good thing for the project, to avoid too much cruft. However it will probably require you to update your application (unless you did follow the deprecations very closely).Some of the main API changes are:avcodec encoding+decoding changeSingle API for Audio & VideoDecoupled codec input & outputnew callback allowing encoders to output data into user-managed buffersAVFrame based API in swscaledisentangled avformat and avcodecdemuxers no longer embed an entire decoder contextnew bitstream filtering APIcan be used as codec header analyzercodec/format registration APIs removed, all formats are always registeredtype safety: int to size_t replacements in various APIslibavresample removalIn the meantime, you can still use FFmpeg 4.4, that is still supported
