Bug ID: 410443
Summary: No sound (mostly) when scrolling in preview or
timeline
Product: kdenlive
Version: 19.04.3
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: czart.and...@gmail.com
Target Milestone: ---
SUMMARY
Most of the time, I have no sound when I'm scrolling in the preview window with
my mouse wheel.
The last kdenlive which is working is 18.12.2. In this version when I scroll in
the preview window, the preview playback goes frame by frame, and the audio of
that frame is played back. Also, when I drag the line of the current position
in the timeline, the audio is working.
With newer versions than 18.12.2, the audio playback is not working as it
should: When 'm scrolling with the mouse wheel, or drag the line in the
timeline, the audio is played back about every fifth frame. Mostly there is no
sound. Also, in the middle of the screen on the right side, the sound bars show
there is no sound: so when I scroll with the mousewheel, most of the time I
hear no sound, and kdenlive indicated there is no sound in the soundbar, and in
about every fifth frame I see and hear the sound of the frame. When I play back
the clip or timeline, the video and audio is working perfectly.
STEPS TO REPRODUCE
1. Load a video clip (which countains sound) to the project bin and timeline.
2. Add the video clip to the timeline.
3. Hover the cursor to the Clip monitor or Project monitor window, and use the
mouse wheel to play the video frame by frame.
OBSERVED RESULT
The video plays frame by frame, but most of the time there is no sound.
EXPECTED RESULT
The video should be played back frame by frame, and also the sound is played
back which is under the current frame.
