egui-video, a video playing library for egui

plays videos in egui from file path or from bytes using ffmpeg library as the decoder backend

This project was forked from https://github.com/n00kii/egui-video which appeared abandoned.

This is not a performant implementation of video playback, as it renders each frame to an egui::ColorImage, and all video decoding is done on the CPU. However it does provide a simple way to add video playback to an egui application.

usage:

/* called once (top level initialization) */

{ // if using audio...
    let audio_sys = sdl2::init()?.audio()?;
    let audio_device = egui_video::init_audio_device(&audio_sys)?;

    // don't let audio_device drop out of memory! (or else you lose audio)

    add_audio_device_to_state_somewhere(audio_device);
}

/* called once (creating a player) */

let mut player = Player::new(ctx, my_media_path)?;

{ // if using audio...
    player = player.with_audio(&mut my_state.audio_device)
}

/* called every frame (showing the player) */
player.ui(ui, [player.width as f32, player.height as f32]);

current caveats

• need to compile in release or opt-level=3 otherwise limited playback performance
• bad (playback, seeking) performance with large resolution streams
• seeking can be slow (is there better way of dropping packets?)
• depending on the specific stream, seeking can fail and mess up playback/seekbar (something to do with dts?)
• no audio playback
