RogueFetch

RogueFetch does not bypass access controls and does not support DRM-protected streams. It is a retrieval and conversion utility, not a circumvention tool.

Versions before 1.1.2 cut a filename short at a dot in the title. A track called “Artist ft. Someone – Song Title” was saved as Artist ft.mp3, because everything after the last dot was mistaken for the file extension. Where several downloads shortened to the same name they stacked up as (1), (2) and so on.

This is fixed from 1.1.2 onward, and files already saved keep the names they were saved with. They are recoverable, though: the truncation happened after the tags were written, so the files still carry their real titles. rename_from_tags.py rebuilds the names from those tags. It needs Python 3.10 or newer and FFmpeg: it uses the copy RogueFetch installed if it is there, and otherwise any ffprobe on your PATH.

It renames a file only when the rebuilt name actually starts with the surviving one, so it restores rather than guesses, and it reports anything it cannot rebuild instead of inventing a name. It changes nothing until you pass --apply, never deletes or overwrites, and writes an undo log that puts every name back.

RogueFetch bundles FFmpeg, used under the GNU Lesser General Public License, version 3. The bundled binaries are unmodified. RogueFetch runs ffmpeg.exe as a separate process and links no FFmpeg library into itself.

The bundled build is ffmpeg-n7.1.5-2-g998de74adf-win64-lgpl-shared-7.1, from FFmpeg’s release/7.1 branch at commit 998de74adf, produced by BtbN/FFmpeg-Builds at release tag autobuild-2026-07-13-14-11.

The FFmpeg libraries ship as separate DLLs, so you can replace them with your own compatible build by swapping the files. No relinking is required. The full licence text and build provenance ship inside both packages.
