✨ NAME ✨

MP4GetDuration — Get the duration of the movie (file) 🎥⏱️

---

🌸 SYNTAX 🌸

#include <mp4.h>

MP4Duration MP4GetDuration(
     MP4FileHandle hFile
)

look at her, so clean, so minimal, no notes 💅

---

🎀 ARGUMENTS 🎀

• hFile — Specifies the mp4 file to which the operation applies. basically you're handing her the file you wanna interrogate, and she's like "bet, say less" 🗂️

---

🦋 RETURN VALUES 🦋

She hands you back the duration of the movie (file), measured in movie (file) time scale units. yes, those specific units, we'll get into it, stay with me 📏✨

---

💜 DESCRIPTION 💜

So MP4GetDuration returns the maximum duration of all the tracks in the specified mp4 file. not just one track, not an average, the MAX. she's finding the longest track in the whole file and reporting that as the movie's duration, main character behaviour tbh 👑

⚠️ Caveat, bestie, listen up: the duration is in movie (file) time scale units. Not seconds. Not milliseconds. Movie time scale units. Do NOT come for her later being like "why is this number so weird", because she told you 😭
