💖 NAME 💖

MP4WriteRtpHint — Write an RTP hint. (Yep, this is the MP4(3) page from the MP4 File Format Library, and we're about to make hint-writing make sense, bestie. 💅)

✨ SYNTAX ✨

The vibe check for calling this function is literally:

       #include <mp4.h>

       bool MP4WriteRtpHint(
            MP4FileHandle hFile,
            MP4TrackId trackId,
            MP4Duration duration,
            bool isSyncSample = true
       );

🎀 ARGUMENTS 🎀

• hFile — specifies the mp4 file that the operation applies to. It's the file we're doing the thing to, periodt.
• trackId — specifies the hint track that the operation applies to. So, like, which hint track are we blessing with this write? That one.
• duration — the duration for this hint sample. Typically it's the same duration as the corresponding sample in the reference media track. ⚠️ Caveat: the duration should be in hint track timescale units, and again that's typically the same as the reference media track.
• isSyncSample — the sync/random access flag for this sample. Typically it's the same as the corresponding sample in the reference media track. No cap.

🎁 RETURN VALUES 🎁

Upon success, true (1). Upon an error, false (0). So either it ate, or it flopped. 😭

🌸 DESCRIPTION 🌸

MP4WriteRtpHint writes the current pending hint created with MP4AddRtpHint() to the specified hint track. That's the whole plot, bestie. It's giving "take the hint that's already waiting and put it where it belongs." 💖
