| * Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | | | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Rename av_fill_image_max_pixstep() to av_fill_image_max_pixsteps().Stefano Sabatini2010-08-20
| | | | | | | | | | The plural form is preferred as it is more consistent with the other functions: av_fill_image_linesizes() av_fill_image_pointers() and looks semantically more correct as it fills an array of elements. Originally committed as revision 24851 to svn://svn.ffmpeg.org/ffmpeg/trunk
