FLAC file fails to parse unless filename identifies it as FLAC

[esceral]

I have a FLAC file which MediaInfo parses correctly only if it knows the filename and that has the correct extension, producing nonsense otherwise:

I can share the file privately if needed.

I have a FLAC file which MediaInfo parses correctly only if it knows the filename and that has the correct extension, producing nonsense otherwise:

The MPEG Audio parser catches the stream and it is before the FLAC parser when there is no file extension :(.

I can share the file privately if needed.
