Subject: configure: hack around broken mplex 2.0.0 headers in mplex check
X-Git-Tag: 1.19.3~507^2~15965^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8f1a67896b58bcd4b378bbaf71ad377a800989a6;p=platform%2Fupstream%2Fgstreamer.git

configure: hack around broken mplex 2.0.0 headers in mplex check

Due to the addition of an unconditional inclusion of config.h in
mjpegtool 2.0.0's stream_params.h header the autoconf test for the
mplex module failed. Hack around this in the same way we did for
mpeg2enc.
