Subject: fix signal/slots for QVector<int16_t>
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=83471f30916e27fe2caa49080096aaf4572a75dd;p=kdenlive

fix signal/slots for QVector<int16_t>
used now for audiosignal.cpp but looks a bit slower (so only commented
out first)

svn path=/trunk/kdenlive/; revision=5117
