ONVIF::...aStream(3)

💅 ONVIF::...aStream(3) — bestie edition 🎀

Okay so this is the manual page for the ONVIF::...aStream(3) situation, and honestly? It's a whole vibe. Let me walk you through it, no cap.

---

✨ NAME ✨

ONVIF::Analytics::Elements::MetadataStream — that's the whole name, periodt. It's a Perl data type class for the XML Schema defined element MetadataStream from the namespace http://www.onvif.org/ver10/schema. That namespace URL? Copy it exactly, bestie, every character. 🫶

---

🔥 DESCRIPTION 🔥

So basically this is a Perl data type class, and it exists for one job: representing the XML Schema defined element MetadataStream that lives in the namespace http://www.onvif.org/ver10/schema.

That's it. That's the whole gig. It's giving "small but mighty" and honestly we stan a focused class. 👑

🌸 METHODS 🌸

🦋 new

my $element = ONVIF::Analytics::Elements::MetadataStream->new($data);

Bestie. Listen. This is the constructor. It makes you a brand new shiny element object, and it will accept the following data structure — and oh my god, look at it. It's huge. It's iconic. It's a little unhinged. 💀

Heads up: nested inside there are notes saying "One of the following elements." and "No occurrence checks yet, so be sure to pass just one..." — that's real, that's the module talking, and it means exactly what it says. There are no occurrence checks. So please, for the love of everything, pass just one. 🙈

{ # ONVIF::Analytics::Types::MetadataStream
  # One of the following elements.
  # No occurrence checks yet, so be sure to pass just one...

      },

    Extension =>  { # ONVIF::Analytics::Types::MetadataStreamExtension2
    },
  },
},

Like, the way MetadataStream can hold a VideoAnalytics (which is a VideoAnalyticsStream, which holds a Frame, which holds PTZStatus, Transformation, Object, ObjectTree, and an Extension...) — it's giving nesting dolls. It's giving "I contain multitudes." And then PTZ is its own PTZStream with its own PTZStatus and Extension, and Event is just $some_value typed as anyType, and Extension opens up into MetadataStreamExtension with an AudioAnalyticsStream in it. 🌀

And under Object → Appearance → Class → Extension (ClassDescriptorExtension) you get OtherTypes (OtherType) with Type as a string and Likelihood as a float, plus an Extension of type ClassDescriptorExtension2. Ngl, the type names are so long they're basically a personality trait. 😭

Also lowkey obsessed with the Rename, Split, and Merge entries under ObjectTree — all three with lowercase from and to keys, plus a bare Delete. Copy the case exactly, bestie, because from ≠ From and Perl will NOT be forgiving. 💅

Okay so that's the whole page, and you ate that. Go forth and pass exactly one element, bestie. 💖
