I work on the receiving end of media processing nowadays, and the overlap of variety in formats, codecs, and configurations is frustrating. No two encoders work the same way, and they often "innovate" in fun and varied ways that almost feel like renewed attempts to make decoders crash.

My hell was trying too make sense or and organise audio/music ID3 tags. What a nightmare that is. EXIF seems much nicer to me.

that sounds endlessly frustrating
