MP4(3)

📦 version 2.1.0, in fedora 43, fedora 44

💖 MP4(3) — the MP4 File Format Library era 💖

okay bestie, this is a page from the MP4 File Format Library manual (that's the MP4(3) bit, it's giving section 3, library calls, very demure) ✨

🎀 NAME 🎀

MP4AddRtpESConfigurationPacket — add ES configuration information to an RTP hint. that's it, that's the whole job, and she does it flawlessly 💅

🌸 SYNTAX 🌸

#include <mp4.h>

bool MP4AddRtpESConfigurationPacket(
     MP4FileHandle hFile,
     MP4TrackId trackId
);

yes bestie, that's the whole signature, don't skip the #include, she NEEDS it 🫶

🦋 ARGUMENTS 🦋

  • hFile — tells you which mp4 file we're doing the operation on. the file in question. the one. 👑
  • trackId — tells you which hint track we're doing the operation on. yes, specifically the hint track, not just any old track, read the label girlie 🔥

✨ RETURN VALUES ✨

  • on success? true (1). ate. 💅
  • on error? false (0). and that's the vibe check failing 😭

🌈 DESCRIPTION 🌈

so MP4AddRtpESConfigurationPacket adds a packet to the current RTP hint, and that packet contains a copy of the elementary stream configuration information of the reference media track. literally a lil copy, tucked in there 🎀

and why do we care? because some RTP payloads require this info to be transmitted either at the start of streaming or periodically during streaming. so like, it's not optional for those payloads, it's mandatory, periodt 🧚
