Bug ID: 481015
Summary: Rendering of custom audio presets crash
Classification: Applications
Product: kdenlive
Version: 23.08.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY:
I have tried to export an audio stream using a new custom audio preset, in the
category of 'audio only'.
It is based into the 'Only Audio AAC 128k [Davy]' preset which is available
into the 'Download new presets' button, present in the preset window.
The aforementioned preset renders successfully the audio, but has the
disadvantage of setting the audio bitrate to 128k, so i have decided to 'clone'
that preset, and modify the audio bitrate, to make it use a VBR audio (as the
.mp3 default audio preset).
After doing this, using 'Saving current preset as a new custom preset' button,
i modified the option and set the 'Rate Control' to 'VBR - Variable Bitrate'
and set the 'Quality' to '5' (I also would like to know how this quality thing
works, i would like to 'preserve' the quality as the original audio, but i am
not sure which value makes that).
Then, i select the new preset to render, i press render, and the rendering
crashes, dropping the log shown into 'OBSERVED RESULT' section.
STEPS TO REPRODUCE
1. Download 'Only Audio AAC 128k [Davy]' audio preset using the Kdenlive
'Download new presets' button
2. Clone the previous mentioned preset using 'Saving current preset as a new
custom preset' and set the 'Rate Control' to 'VBR - Variable Bitrate' and set
the 'Quality' to '5' , under the 'Audio' tab of the new preset.
3. Render the project using the new preset, and the process crashes the preset.
OBSERVED RESULT
No LADSPA plugins were found! Check your LADSPA_PATH environment variable.

ADDITIONAL INFORMATION
MLT : Version 7.22.0
I have checked that other presets works, and that i have the formentioned MLT
libraries, but they do not have the 'number' behind, as maybe the program is
looking for.
Example:
/usr/lib/mlt-7/libmltmovit.so --> This one exists
/usr/lib/mlt-7/libmltmovit.so.8 --> This one does not
