💖 MP4SetHintTrackSdp — the vibe check

okay so bestie, we're in MP4(3), the MP4 File Format Library, and today's main character is MP4SetHintTrackSdp ✨ — she sets the SDP media level description of the hint track. iconic behavior honestly.

✨ NAME ✨

MP4SetHintTrackSdp — sets the SDP media level description of the hint track 🎀

🌸 SYNTAX 🌸

#include <mp4.h>

bool MP4SetHintTrackSdp(
     MP4FileHandle hFile,
     const char* sdpString
)

like yes, that's the whole signature, no notes 💅

🦋 ARGUMENTS 🦋

  • hFile — this is the mp4 file the operation applies to, bestie. the one we're doing the thing to 🫶
  • sdpString — the new value of the hint track sdp string. brand new, fresh out the box, slay ✨

👑 RETURN VALUES 👑

  • on success you get true (1) 🎉
  • on an error you get false (0) 😭

that's it. binary. no in-between. periodt.

💜 DESCRIPTION 💜

so MP4SetHintTrackSdp sets the SDP (IETF RFC 2327) media level fragment for the hint track. the way that it just... handles the fragment?? obsessed 💅

and what's it for, you ask? a streaming server uses it to create a complete SDP description of the multimedia session represented by the file. so like, the server's whole little picture of the session? built off this. no cap, that's the point 🌈
