New issue by oldlaptop on void-packages repository

https://github.com/void-linux/void-packages/issues/43214

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.21_1 x86_64-musl AuthenticAMD notuptodate rF

### Package(s) Affected

shotcut-22.01.30_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

Not applicable.

### Expected behaviour

When told to open a variable-frame-rate video file, shotcut offers to convert it to a more sensible format for editing purposes, and attempts to do this with ffmpeg (meaning the binary `/usr/bin/ffmpeg`).

### Actual behaviour

shotcut does not depend directly or indirectly on ffmpeg, meaning it's possible to have it installed without ffmpeg and have the conversion fail. (I've just had the dependencies actually shake out that way for me in a fresh installation.)

### Steps to reproduce

Install shotcut, do not install ffmpeg, attempt to open a variable-frame-rate video file in shotcut, and accept its offer to convert the file to a better format for editing.
