'''Summary of the bug:'''
I have my music library in FLAC Uncompressed, and I have an issue with at
least one file, when using it with FFmpeg -ss option, in Windows.
If I convert this file to FLAC level 0 it works fine.
I'm using FFmpeg 4.1 Windows.
'''How to reproduce:'''
When using FFmpeg -ss with that file FLAC Uncompressed:
ffmpeg -ss 15 -i "02 - Sad But True.uncompressedNotWorking.flac" out.flac
2> log.txt
Errors:
