In Quantal (12.10), libavutil-dev can only be installed if libavutil51 is installed, there's no option for it to depend on libavutil-extra-51. Since libavcodec-dev depends on libavutil-dev, both packages will be uninstalled if we try to install libavcodec-extra-53. The attached patch uses the Depends fields that were in the control file for 12.04, this way libavcodec-dev and libavutil-dev can be installed in parallel with libavcodec-extra-53 and libavutil-extra-51
