Only your 'distro' can clarify what the difference between the packages (however you didn't name it!).
libavcodec-dev probably contains headers (.h) and libraries (.a) for development (to build applications based on libavcodec). libavcodec-unstripped-52 probably contains unstripped binaries which can be used for debugging purposes; libavcodec52 probably the main version with dynamic library avcodec; libavcodec-extra-52 probably build with some extra flags or/and extra dependencies. If you look here <http://packages.ubuntu.com/ru/karmic/libavcodec-extra-52>and here <http://packages.ubuntu.com/en/karmic/libavcodec52> you'll notice that extra version additionally depends on these libraries: - libdirac0c2a <http://packages.ubuntu.com/ru/karmic/libdirac0c2a> general purpose video codec - library - dep: libfaad0 <http://packages.ubuntu.com/ru/karmic/libfaad0> (>= 2.6.1) freeware Advanced Audio Decoder - runtime files - dep: libmp3lame0 <http://packages.ubuntu.com/ru/karmic/libmp3lame0> An MP3 encoding library - dep: libopenjpeg2 <http://packages.ubuntu.com/ru/karmic/libopenjpeg2> JPEG 2000 image compression/decompression librar - libx264-67 <http://packages.ubuntu.com/ru/karmic/libx264-67> (>= 1:0.svn20090502) x264 video coding library - dep: libxvidcore4 <http://packages.ubuntu.com/ru/karmic/libxvidcore4>(>= 1:1.0.0-0.0) High quality ISO MPEG4 codec library 2011/4/12 Kip Warner <[email protected]> > Hey list, > > My distro has four packages for the libavcodec that I can see.
