MP4AppendHintTrackSdp 💖

okay bestie, you found it — this is the manual page for MP4AppendHintTrackSdp from the MP4 File Format Library, and yes it's a section 3 page (that's the C library section, iykyk). grab a boba, we're doing this 🧋✨

🌸 NAME 🌸

MP4AppendHintTrackSdp — the girl whose whole job is adding stuff to the SDP media level description of the hint track 💅

✨ SYNTAX ✨

#include <mp4.h>

bool MP4AppendHintTrackSdp(
     MP4FileHandle hFile,
     const char* sdpString
)

like, that's it. two args, one bool, we love a low-maintenance icon 🫶

🎀 ARGUMENTS 🎀

  • hFile — the mp4 file we're doing the operation on. this is your main character, the file everything applies to 💖
  • sdpString — the addition to the hint track sdp string. literally the extra text you want tacked on, no cap.

👑 RETURN VALUES 👑

  • success? you get true (1). slay. ✅
  • error? you get false (0). not slay, but we move. 😭

💜 DESCRIPTION 💜

so MP4AppendHintTrackSdp appends the string you gave it to the SDP (IETF RFC 2327) media level fragment for the hint track. that's the whole vibe.

who is this for? a streaming server — because it needs to build a complete SDP description of the multimedia session that the file represents. the way that a server just needs all the pieces assembled... obsessed. 🌈

basically: you bring the fragment, this function sticks it on the end, the streaming server gets the full picture. team effort fr fr 🦋

🔥 SEE ALSO 🔥

⚠️ heads up bestie: this one is MP4AppendHintTrackSdp — the append girl. if you wanted to get the sdp or set it, that's a different function, check the see-also list above 💀

k that's the whole page, mwah 💋 this manual came to you from Cisco Systems Inc., Version 0.9 — go forth and append responsibly, bestie 🎀💖✨
