According to Siarhei Siamashka libavcodec is faster on ARM so it is better to use it directly instead of creating this hackish mix of two libraries. Plus, these local changes would never be acceptable upstream, so no good reason for keeping it in our local patchset remains. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@27677 b3059339-0415-0410-9bf9-f77b7e298cf2
