14 DAY TRIAL // FFmpeg, a complete solution to record, convert, and stream audio and video, has been upgraded to version 2.6.3 and is now available for download and testing.
The new 2.6.x branch of FFMpeg has been around for a while now, and this is just a maintenance release. All of the packages in the FFmpeg have been upgraded and numerous fixes have been implemented. As it stands right now, this is the most advanced version available, and it should arrive soon in the repositories.
"2.5.6 was released on 2015-04-19. 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," reads the official website.
The following packages have been upgraded: libavutil, libavcodec, libavformat, libavdevice, libavfilter, libavresample, libswscale, libswresample, and libpostproc. FFmpeg is the leading multimedia framework able to decode, encode, transcode, mux, demux, stream, filter, and play virtually any media that humans and machines have created.
A complete list of updates, features, and other fixes can be found in the official announcement. The source package for FFmpeg can be downloaded from Softpedia, but this is just the source. You will need to compile it yourself, although it would be a better idea to wait until it hits the repositories.
