How MP4 to WAV audio conversion works

MP4 probe and decode → stream-aware conversion → WAV audio verify

Reading MP4

MP4 input is probed for its video, audio, subtitle, chapter, rotation, color, metadata, and encryption streams before conversion.

Creating WAV audio

WAV output extracts one selected audio stream as uncompressed PCM within the browser limits.
