Avcodec.library is an Amiga port of the open source ffmpeg project's libavcodec static library ( http://sourceforge.net/projects/ffmpeg)distributed under the GNU Lesser General Public License.
The actual Amiga port of the avcodec.libray (used for DVplayer) is now quite old (51.52 from 2008) and there are lots of features, corrections and improvements on the original avcodec sourcecode that the Amiga version of avcodec.library doesn’t contain.
