[mythtv] ERROR: x264 not found

[Paul Mathews]

When compiling mythtv .20 with the --enable-x264 option, I get an 'ERROR: x264 not found'. x264 is up to date from svn sources.

my config.err:

gcc -c -o /tmp/ffmpeg-conf-633-4639-2466.o /tmp/ffmpeg-conf-6063-4639-405.c
gcc -Wl,--warn-common -o /tmp/ffmpeg-conf-19579-4639-25294 /tmp/ffmpeg-conf-633-
4639-2466.o -lm -lz -lx264

Thanks in advance!
