a video playing library for `egui`

egui-video, a video playing library for egui

main_L3Yxngkb7T.mp4

plays videos in egui from file path or from bytes

dependancies:

• requires ffmpeg 6. follow the build instructions here
• requires sdl2. by default, a feature is enabled to automatically compile it for you, but you are free to disable it and follow these instructions

usage:

/* called once (top level initialization) */

{ // if using audio...
    let audio_device = egui_video::AudioDevice::new()?;
    
    // 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 = egui_video::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.size);

contributions

are welcome :)

current caveats

• need to compile in release or opt-level=3 otherwise limited playback performance

egui-video's Issues

Make elapsed time and duration public

(in order to write custom OSC)

compile error

Add subtitle support

I tried to think of a way to create a pull request myself, but the subtitle decoder has a different api and it has this single function which takes a packet and a Subtitle buffer. Hence I cannot fit it in the Streamer trait. Any ideas on how to go about it? I know I have been troubling you a lot recently, but can you look into it?

Please and thank you.

Video and audio desync

It usually only takes a couple seconds, at most 30 seconds.
(Yes, I am compiling on release build).

I did this:

        //let frame_timer_guard = self.frame_timer.schedule_repeating(video_wait_duration, move || {
        let frame_timer_guard = self.frame_timer.schedule_repeating(Duration::zero(), move || {
            play(&video_streamer_ref);
            ctx.request_repaint();
        });

and it did not have trouble decoding video unthrottled, so it's not a problem of getting frames to the GPU.

I did this test real quick with OBS and the example program:
Video
so the video stream is playing slightly too fast on my machine.

(I also tried this on chubby1968's fork (commit 7abbc48), and I have the same problems.)
