[MPlayer-users] configure in cvs

[Robert Henney]

I've found that in order to get mplayer svn to build against the current
ffmpeg svn revision 7182, line 1590 of configure needs to be changed from:

_libavparsers=`grep 'av_register_codec_parser(&[a-z]' libavcodec/allcodecs.c | sed 's/.*&\(.*\)).*/\1/'`

to something along the lines of:

_libavparsers=`grep '^[^#]*REGISTER_PARSER' libavcodec/allcodecs.c | sed 's/.*, *//;s/).*//'`

from the looks of it this is due to a recent cleanup of allcodecs.c,
making the existing way configure was grepping out some needed info from
it no longer work.
