14 DAY TRIAL // FFmpeg is a complete solution to record, convert, and stream audio and video. The developers have been quick to release a new version of this collection of tools and libraries in order to improve upon a few things.
Just like the previous update that arrived only a few days ago, FFMpeg 2.5.2 is a rather boring maintenance update for the 2.5.x branch. It's not anything out of the ordinary and it will probably reach repositories in a short while, or at least most of them.
"2.5.2 was released on 2014-12-23. It is the latest stable FFmpeg release from the 2.5 release branch, which was cut from master on 2014-12-15. Amongst lots of other changes, it includes all changes from ffmpeg-mt, libav master of 2014-12-03, libav 11 as of 2014-12-03," is noted on the official website. This branch has the codename "Bohr" and you might find it easier to keep track of the major upgrades by referring to this name.
A number of packages have been updated, including libavutil, libavcodec, libavformat, libavdevice, libavfilter, libavresample, libswscale, libswresample, and libpostproc. As you all know, FFmpeg is the leading multimedia framework able to decode, encode, transcode, mux, demux, stream, filter, and play pretty much any media that humans and machines have created.
A complete list of updates, features, and other fixes can be found in the official announcement. You can download the FFmpeg 2.5.2 source code right now from Softpedia, but unless you really know what you are doing, then you should wait until it reaches the repository for your distro.
