STRUCT PES_HEADER_WRITE_ARGS(9)

💅 struct pes_header_write_args(9) 💅

ok so this is a page from the Kernel API Manual, and bestie, we're about to get into it — this struct is literally the little ✨gift bag✨ of arguments you hand over when you want a PES header written. think of it as the packing list before the write happens. no cap, every field matters. 🎀

---

✨ NAME ✨

struct pes_header_write_args — the arguments you pass in to write a PES header. that's it, that's the vibe. 🦋

---

🌸 SYNOPSIS 🌸

struct pes_header_write_args {
    void *dest_buf;
    u32 dest_offset;
    u32 dest_buf_sz;
    u32 encoder_id;
    bool send_pts;
    u64 pts;
    bool send_dts;
    u64 dts;
    u16 stream_id;
    u32 n_pes_h_s_bytes;
    u32 access_unit_len;
 };

like, look at her. eleven fields. main character struct energy fr fr. 👑

ok boom, field-by-field breakdown, i got you:

• dest_buf — the buffer you're writing into. the canvas. the destination. the place where the bytes go to live. 💖
• dest_offset — where you start writing inside the dest_buffer. not the beginning, the starting point — offset girlies rise. ✨
• dest_buf_sz — the size of the dest_buffer. know your limits bestie, respect the size. 🎀
• encoder_id — the encoder id (peep vidtv_encoder.h for the deets 👀). this is how we know which encoder we're dealing with.
• send_pts — a bool: are we sending PTS or not? yes/no, in or out, no in-between. 🦋
• pts — the actual PTS value to send. the number itself. iconic. ⭐
• send_dts — a bool again: should we send DTS? another vibe check, another yes/no. 🌸
• dts — the DTS value to send. matching set with pts, we love a duo. 💜
• stream_id — the stream id to use. for example: Audio streams (0xc0-0xdf), Video streams (0xe0-0xef). pick your lane, pick your id. 🎯
• n_pes_h_s_bytes — padding bytes 💀. an encoder might use them if it needs to, and the decoder just throws them away — discarded, gone, not invited to the afterparty. 🙈
• access_unit_len — the size of one access unit (including any headers it might need). note the emphasis on _one_ — singular. one unit. one vibe. 🔥

ok that's the whole page!! mwah 💋 this was brought to you by ./drivers/media/test-drivers/v..., dated October 2026, and no i will not be normal about a kernel struct. slay, periodt, see you in the next manpage bestie 🍓💅
