💖 MP4SetSessionSdp — the glow-up edition 💖

okay bestie, so this is a page from the MP4 File Format Library, aka the MP4(3) manual. no cap, it's a whole library and this one function is about to be your new obsession. let's get into it ✨

🌸 NAME 🌸

MP4SetSessionSdp — set the SDP session level description of the file. yes, that's the whole job. she's focused, she's unbothered, she sets the SDP. periodt 💅

🎀 SYNTAX 🎀

#include <mp4.h>

bool MP4SetSessionSdp(
     MP4FileHandle hFile,
     const char* sdpString
)

literally just include the header and call her. that's it, that's the whole vibe 🦋

🫶 ARGUMENTS 🫶

  • hFile — which mp4 file we're doing this to. the operation applies to this one, bestie, so pick wisely.
  • sdpString — the brand new value of the session sdp string. this is the main character of the whole call ngl.

✨ RETURN VALUES ✨

  • on success? true (that's 1, slay 👑)
  • on an error? false (that's 0, we don't talk about it 😭)

💜 DESCRIPTION 💜

okay so here's the tea: MP4SetSessionSdp sets the SDP (that's IETF RFC 2327, write that down) session level fragment for the file. 📝

and why do we care, you ask? because a streaming server uses it to create a complete SDP description of the multimedia session that the file represents. so like, without this, the streaming server is just out here with no context. with it? she knows exactly what she's serving. iconic behaviour fr fr 🔥

🦋 SEE ALSO 🦋

go read those too, they're all part of the same friend group 🌈

ngl this one's short and sweet, but that's the assignment. set the sdp, return your bool, go live your life 🍓
