✨ NAME ✨

XvVideoNotify — the event that gets generated for video processing 🦋

---

🌸 SYNOPSIS 🌸

#include <X11/extensions/Xvlib.h>

     typedef union {
       int type;
       XvVideoNotifyEvent xvvideo;
       XvPortNotifyEvent xvport;
       long pad[24];
     } XvEvent;

     typedef struct {
       int type;
       unsigned long serial;
       Bool send_event;
       Display *display;
       Drawable drawable;
       unsigned long reason;
       XvPortID port_id;
       Time time;
     } XvVideoNotifyEvent;

okay so let's break down every single field because they ALL matter, no skips 💅

• type — tells you what kind of event this is: XvVideoNotify. that's literally it, that's the vibe.
• serial — the number of the last request the server processed. like a receipt number bestie 🧾
• send_event — True if this event came from a SendEvent request. False means it's the real deal, homegrown, organic ✨
• display — a pointer to the display the event was read from. your connection, your girl 🫶
• drawable — the drawable the event was generated for. the canvas in question 🎨
• reason — why this event happened. one of: XvStarted, XvStopped, XvPreempted, XvBusy, XvHardError. the lore, basically 👑
• port_id — the port that's processing the video the event is about. this is the port's whole identity fr fr 💜

---

💫 DESCRIPTION 💫

so, XvVideoNotify events show up when video gets started, stopped, preempted by some other video request, ignored because the port is grabbed by another client (rude, honestly 😭), or interrupted because of a hard transmission or reception error 💀.

that's the whole vibe check. video does a thing, the event tells you about it. iconic behaviour, no notes 🔥
