Processing demand varies with the codecs found in the source during this M4P-to-FLAC job.
High-resolution M4P footage increases conversion time and memory use.
Review the beginning and end of FLAC after the download finishes.

FLAC serves music archives, mastering, and lossless playback, whereas M4P commonly serves legacy Apple library compatibility.
For M4P-to-FLAC delivery, plan for larger files than lossy formats.
After leaving M4P, the receiving app must support the streams encoded inside FLAC, not only its extension.

M4P to FLAC taking too long? Process a shorter section to determine whether file size is the bottleneck.
FLAC converted from M4P not opening? Test a compatible player and inspect the output streams.

When does M4P to FLAC conversion make sense?

It is useful when M4P media created for older Apple libraries must enter a FLAC system designed for lossless distribution.

Where is the M4P source processed?

The browser prepares FLAC from M4P on this device instead of sending the source to a remote conversion server.
