Analyzer final class

Minn\Media\Av\Analyzer · public/minn/src/Minn/Media/Av/Analyzer.php · 114 lines

A media file's analysis, keyed as the reference's media reader keys the one it hands to the wp_read_audio_metadata and wp_read_video_metadata filters (probe media-meta): the file's size, format and type, its audio and video streams, its playing time and bitrate, and its tags. The format is found by the file's first bytes; a file named .mp3 with none is still typed as MPEG audio.
