Bug ID: 505401
Summary: Speech to text - Whisper can no longer process after
24.12.3 to 25.04.1 update, Mac OS Sequoia 15.5
FileNotFoundError: [Errno 2] No such file or
directory: 'ffmpeg'
Classification: Applications
Product: kdenlive
Version First 25.04.1
Reported In:
Platform: macOS (DMG)
OS: macOS
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface & Miscellaneous
Assignee: j...@kdenlive.org
Reporter: hge...@yahoo.com
Target Milestone: ---
SUMMARY
After working flawlessly and reliably before update, trying to generate text
from video audio results in consistent error that appears related to inability
to find or communicate with secondary applications. I have removed the plug-in
and reinstalled, as well as reinstalled kdenlive and problem persists. Whisper
is configured using kdenlive, not independently.
STEPS TO REPRODUCE
1. Load a video clip into the project.
2. Attempt to generate subtitles.
3. Exports text, then when attempting to process the audio, it generates an
error and fails.
OBSERVED RESULT
Produces the following failure log (copied in full):
/Applications/kdenlive.app/Contents/Resources/scripts/whisper/whispertotext.py:59:
FutureWarning: You are using `torch.load` with `weights_only=False` (the
current default value), which uses the default pickle module implicitly. It is
possible to construct malicious pickle data which will execute arbitrary code
during unpickling (See
https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for
more details). In a future release, the default value for `weights_only` will
be flipped to `True`. This limits the functions that could be executed during
unpickling. Arbitrary objects will no longer be allowed to be loaded via this
mode unless they are explicitly allowlisted by the user via
`torch.serialization.add_safe_globals`. We recommend you start setting
`weights_only=True` for any use case where you don't have full control of the
loaded file. Please open an issue on GitHub for any issues related to this
experimental feature.

There were no errors with previous version, and other applications can find

Successful processing of audio to text.
