Playback, audio distortion when starting playback, click in timeline plays 1 frame of audio
I assume this is a MLT issue as I have the same test results in Kdenlive and in Shotcut (https://github.com/mltframework/mlt/issues/860
merged https://github.com/mltframework/mlt/commit/49398ce87c7ac4123044188b3d3287705df04213).
reverted https://github.com/mltframework/mlt/commit/6f29f407a6cba469d2f32b6620b6e3244778f9b4
final merged: https://github.com/mltframework/mlt/commit/2c614ae902c9b331f93dd7952e1d23e178da6d69 and Shotcut updated: https://github.com/mltframework/shotcut/commit/9c991ecba0f7c5cdc57a1f3fec98ae46c775a07f
STEPS TO REPRODUCE (on Windows)
- Add an A/V clip in the timeline
- Add an effect on the clip (Shotcut:
Size, Position & Rotate, Kdenlive:Position and Zoom) - Adjust effect parament i.e., resize and position
- Add an audio clip in the timeline
- Start playback
OBSERVED RESULT
Audio distortion of first 500 – 1000ms when starting playback,
ADDITIONAL INFORMATION
When the effect is disabled no Audio distortion when starting the playback.
Maybe related to: https://github.com/mltframework/mlt/issues/441 -> problem with SDL audio backend.
Project setting: 1080p25
MAYBE RELATED
With above setting: clicking in timeline plays 1 frame of audio. Tested on Kdenlive and Shotcut. -> This happens only when audio scrubbing is enabled.
