239 version from SVN. If the latest version fails, report the problem to the
240 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
242 if disabled logging; then
244 Rerun configure with logging enabled (do not use --disable-logging), and
245 include the log this produces with your report.
