+Subject: [PATCH] Use auto for AVCodec
+
+The geniuses over at FFmpeg decided to constify this API, so old
+versions of the library will return AVCodec *, while new versions
+of the libary will return const AVCodec *, which, in C++, are not
+OK to convert between.
+
+Rather than use some macro hell in ffmscompat.h, we can work around
+this by using auto.
+
+Gross.
