Andreas Rheinhardt 423b6a7e49 avutil/imgutils: Add wrapper for av_image_copy() to avoid casts
av_image_copy() accepts const uint8_t* const * as source;
lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.

This commit changes this by adding a static inline wrapper
for av_image_copy() that casts between the two types
so that we do not need to add casts everywhere else.

README

FFmpeg examples README
----------------------

Both following use cases rely on pkg-config and make, thus make sure
that you have them installed and working on your system.


Method 1: build the installed examples in a generic read/write user directory

Copy to a read/write user directory and run:
make -f Makefile.example

It will link to the libraries on your system, assuming the PKG_CONFIG_PATH is
correctly configured.

Method 2: build the examples in-tree

Assuming you are in the source FFmpeg checkout directory, you need to build
FFmpeg (no need to make install in any prefix). Then just run "make examples".
This will build the examples using the FFmpeg build system. You can clean those
examples using "make examplesclean"

If you want to try the dedicated Makefile examples (to emulate the first
method), go into doc/examples and run a command such as
PKG_CONFIG_PATH=pc-uninstalled make -f Makefile.example
