+ Did you use av_cold for codec initialization and close functions?
+@item
+ Did you add a long_name under NULL_IF_CONFIG_SMALL to the AVCodec or

+@item
+ Did you bump the minor version number in @file{avcodec.h} or
+ @file{avformat.h}?
+@item
+ Did you register it in @file{allcodecs.c} or @file{allformats.c}?
+@item
+ Did you add the CodecID to @file{avcodec.h}?

+ If it has a fourcc, did you add it to @file{libavformat/riff.c},
+ even if it is only a decoder?
+@item
+ Did you add a rule to compile the appropriate files in the Makefile?
+ Remember to do this even if you're just adding a format to a file that is
+ already being compiled by some other rule, like a raw demuxer.
+@item
+ Did you add an entry to the table of supported formats or codecs in the
