Bug ID: 386105
Summary: K3b FFmpeg decode plugin seems to be broken, produces
noise
Product: k3b
Version: 17.08.0
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Plugins
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Target Milestone: ---
The output file contains noise. See the screenshot

The amount of noise increases if input file has lower bitrate.
The audio itself has twice(?) higher pitch than original and also seems to be
faster.
Timing is ok.
Also ffmpeg plugin currently uses deprecated API. This has to be fixed too at
some point.
Distro: Kubuntu 17.10 (Artful)
