Do you need to decode the data with a during conversion?

The modernization of automotive data logging has increasingly shifted toward the ASAM MDF4 (Measurement Data Format version 4.0) standard, creating a growing need for efficient conversion from legacy formats like Vector’s BLF (Binary Logging Format). This transition is not merely a change in file extensions but a strategic move toward universal data interoperability, scalability, and enhanced metadata support within the automotive engineering ecosystem. MF4 allows you to store rich metadata, such

class BLFHandler(FileSystemEventHandler): def on_created(self, event): if event.src_path.endswith('.blf'): mdf = MDF(event.src_path) mdf.save(event.src_path.replace('.blf', '.mf4'), compression=2)

MF4 output is 10x larger than the BLF input. Cause: Default MF4 saves XML data uncompressed. Fix: Use compression=2 (Deflate) or compression=3 (LZ4) when saving: python -m can

BLF is compressed; MF4 by default is not. Enable deflate compression during conversion:
