💖 MP4(3) — MP4 File Format Library 💖

okay bestie, welcome to the MP4 File Format Library manual, third section, and today's main character is literally one little function. it's giving "small but mighty" fr fr ✨

✨ NAME ✨

MP4GetSessionSdp — get the SDP session level description of the file 👑

🌸 SYNTAX 🌸

#include <mp4.h>

const char* MP4GetSessionSdp(
     MP4FileHandle hFile
)

like, that's it. that's the whole vibe. no cap 💅

🎀 ARGUMENTS 🎀

  • hFile — specifies the mp4 file to which the operation applies. that's your file, your baby, your whole entire situation 🫶

🦋 RETURN VALUES 🦋

it hands you back the SDP session level description fragment of the mp4 file. literally the fragment. that's the return value. slay 🌈

💜 DESCRIPTION 💜

so MP4GetSessionSdp returns the SDP (IETF RFC 2327) session level fragment for the file. iykyk, SDP is the whole "here's what this stream actually is" situation.

and what's it for? a streaming server uses it to create a complete SDP description of the multimedia session represented by the file. so it's not the whole picture by itself — it's one piece that the server assembles into the full thing. main character energy, but in a supporting-role kind of way 💅

also!! the mp4broadcaster test program provided with the MP4 library gives an example of using this call to create the complete SDP description. so if you wanna see it in action, that's your girl. go look at her 👀

ngl bestie, that's the whole page. every flag, every argument, every return value — we kept it all. nothing skipped, nothing invented. periodt 💖

and that's a wrap!! this page came to you from Cisco Systems Inc., Version 0.9, filed under MP4(3) in the MP4 File Format Library. obsessed with her, honestly. go build something iconic 🎀✨💅🦋🌸
