New Revision: 38660
Changeset: http://dev.haiku-os.org/changeset/38660
Modified:
haiku/trunk/src/apps/mediaplayer/interface/PeakView.cpp
haiku/trunk/src/apps/mediaplayer/interface/PeakView.h
Log:
Pulse() may run twice before receiving the next
data, so we should prevent showing a current
peak of 0. Fixes the periodic 0 peaks.
Modified: haiku/trunk/src/apps/mediaplayer/interface/PeakView.cpp
