coda_h264_sps_fixup(9)

✨ NAME ✨

okay so bestie, this is coda_h264_sps_fixup(9) from the Kernel API Manual — and it fixes frame cropping values in h.264 SPS. literally its whole job. 💅

🫶 SYNOPSIS 🫶

int coda_h264_sps_fixup (struct coda_ctx *ctx , int width , int height ,
char *buf , int *size , int max_size );

🌸 ARGUMENTS 🌸

• ctx — the encoder context. the main character of this function call, honestly.
• width — visible width. the width you can actually see. 👀
• height — visible height. same vibe, but vertical.
• buf — buffer containing h.264 SPS RBSP, starting with NAL header. yes, it starts with the NAL header, no cap.
• size — modified RBSP size return value. it comes back out through this pointer. 🎀
• max_size — available size in buf. aka how much room you actually have in there.

🦋 DESCRIPTION 🦋

so what it does is rewrite the frame cropping values in an h.264 SPS RBSP correctly for the visible width and height you give it. that's it, that's the whole slay. ✨

it's giving “tiny fixup, very specific job, extremely correct.” no extra drama, no invented behaviour, just cropping values getting fixed for the given visible width and height. periodt. 💖
