dvb_dmx_swfilter_packets(9)

✨ dvb_dmx_swfilter_packets(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're about to meet dvb_dmx_swfilter_packets — the little routine that runs the DVB software filter over a whole buffer stuffed with multiple MPEG-TS packets, each one 188 bytes. yes, every single one. 188. iconic number, no notes 💅

---

🌸 SYNOPSIS 🌸

void dvb_dmx_swfilter_packets (struct dvb_demux *demux , const u8 *buf ,
size_t count );

---

🎀 ARGUMENTS 🎀

• demux — a pointer to struct dvb_demux. that's the demuxer bestie in question 🫶
• buf — the buffer holding the data you want filtered ✨
• count — how many MPEG-TS packets you've got in there, and remember each one is 188 bytes big 🍓

---

🦋 DESCRIPTION 🦋

so what does it actually do? the routine will discard a DVB packet that doesn't start with 0x47 💀 like, if the first byte isn't 0x47, it's not coming to the party. bye.

reach for this routine when the DVB demux fills MPEG-TS buffers that are already aligned — that's literally the whole vibe check here 👑

---

⭐ NOTE ⭐

the buf size should have size equal to count * 188. do the math, bestie, don't make it awkward 😭
