💖 MP4AddRtpHint — the RTP hint adder ✨

okay bestie, welcome to MP4(3), the MP4 File Format Library corner of the universe 🌈. this one's about MP4AddRtpHint and it's lowkey iconic, let's get into it 🫶

---

✨ NAME ✨

MP4AddRtpHint — add an RTP hint 💅

---

🎀 SYNTAX 🎀

#include <mp4.h>

bool MP4AddRtpHint(
     MP4FileHandle hFile,
     MP4TrackId trackId
);

no cap, that's the whole signature, copy it exactly bestie 🦋

---

🌸 ARGUMENTS 🌸

• hFile — tells you which mp4 file we're doing this operation on 📁. it's the file, the main character of the situation.
• trackId — tells you which hint track this operation applies to 🎯. not any track, that track, okay?

---

⭐ RETURN VALUES ⭐

• on success you get true (which is 1) — slay ✨
• on error you get false (which is 0) — not slay, sad girl hours 😭

---

💜 DESCRIPTION 💜

okay so here's the tea ☕: MP4AddRtpHint creates a new hint sample for the hint track you specified, and it also enables the subsequent calls to MP4AddRtpPacket() so those calls can create the RTP packets that belong to this hint 🎀. like, it's setting the whole vibe up so the packets have somewhere to go.

then, once all the RTP packets for the hint have been created, you should call MP4WriteRtpHint() to actually write the hint to the track 📝. that's the step where it becomes real, bestie. don't skip it. the way that order matters… periodt 💅

fr fr: add the hint, make the packets, then write it. that's the pipeline and she's beautiful 🌸
