al_open_video_f(3)

💖 NAME 💖

al_open_video_f — Allegro 5 API. Also hi bestie, this is the al_open_video_f(3) page from the Library Functions Manual, and it's literally about opening a video from an ALLEGRO_FILE* 💅.

✨ SYNOPSIS ✨

#include <allegro5/allegro_video.h>

ALLEGRO_VIDEO* al_open_video_f(ALLEGRO_FILE *fp, const char *ident)

🦋 DESCRIPTION 🦋

Okay so picture this: you already have an ALLEGRO_FILE*, and you want to open a video file from it using the Allegro file interface system. That's the whole main character move here. This lets videos be loaded from custom sources — memory streams, virtual file systems, archives, or literally any other source supported by a custom ALLEGRO_FILE_INTERFACE. Obsessed. ✨

💖 Parameters 💖

• file — a pointer to an ALLEGRO_FILE object. Ownership of this file is transferred to the video object, and the file will be closed automatically when al_close_video is called. So don't be doing double-close drama 🙈.

🔥 Returns 🔥

A pointer to a shiny new ALLEGRO_VIDEO object if it works, or NULL on failure. That's it. No cap.

🎀 Remarks 🎀

• The function does not require the file to be seeked or rewound; it reads from the current position.
• After calling al_open_video_f, you must not manually close the ALLEGRO_FILE; call al_close_video to free all associated resources.
• This function mirrors the behavior of other _f variants in the Allegro API, enabling video streaming from custom file systems.

🌈 Example 🌈

ALLEGRO_FILE *f = al_fopen("video.ogv", "rb");
if (f) {
    ALLEGRO_VIDEO *vid = al_open_video_f(f);
    if (vid) {
        float fps = al_get_video_fps(vid);
        // ... use the video ...
        al_close_video(vid); // also closes f
    }
}

And that's the whole vibe! Footer/source realness: this is from the Allegro reference manual, page al_open_video_f(3) — and there's no date listed down there, so we're keeping it exactly as the footer says. Byeee 🫶💜
