[Kdenlive-devel] Vu Meter

[Marco Gittler]

I made another commit yesterday, with higher values. (Range from -127
to 127 had only a max value of 127 while scale is 255). I had the idea
to change from ByteArray to QList<int> (for greater range), or better
the whole audioframe, so the we could make an abstract audio class,
which can then have, this vu-meter and an histogram for the audiodata.
With that i have also red with mp3. Also Video have now sometimes red
values.
