🎀 ARGUMENTS 🎀

• dev — device pointer. yes, the device pointer, iconic.
• sps — the struct nal_h264_sps to fill from the RBSP data. that's the thing getting filled.
• src — the buffer that contains the RBSP data. the data lives here.
• n — size of src in bytes. count those bytes, bestie.

💅 DESCRIPTION 💅

Read RBSP data from src and use it to fill sps. that's the tea 🍵 No extra steps described, no secret sauce, just that.
