SUMMARY Using this particular preset generates files without audio in the latest version. This is a regression since I used this present in the past and it worked just fine. STEPS TO REPRODUCE 1. Prepare some video 2. Select the preset "WebM-VP9/Opus (libre)" 3. Check that Audio box is selected OBSERVED RESULT Webm file with no audio EXPECTED RESULT Webm file with audio SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 Kernel Version: 5.17.4-arch1-1 (64-bit) Graphics Platform: X11 Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics ADDITIONAL INFORMATION The other two presets in the same category work fine: MP4-H265 (HEVC) and WebM-AV1/Opus (libre).
This problem still occurs as of Kdenlive 22.04.1.
Thank you for reporting. WebM-VP9 seems to have 2 problems. 1. The audio stream is not initiated. Workaround: click on "save currents preset as new customer preset" -> click on "audio" tab -> set all parameters as you want -> try again. 2. On Windows a failure pops up: mlt_repository_init: failed to dlopen C:\CraftRoot\tmp\kdenlive-22.04.0-1_standalone\lib\mlt/libmltjackrack.dll ("C:\CraftRoot\tmp\kdenlive-22.04.0-1_standalone\lib\mlt\libmltjackrack.dll": this module was not found.) But libmltjackrack.dll is available in exact this folder.
