bevy_movie_player

A movie player plugin for Bevy game engine.

[!Warning] Still in development, The API may change in the future.

Supported movie formats

• .gv format (--features gv)
  • using rust-gv-video.
  • alpha channel support.
  • .gv has simple LZ4 compressed + BC1/BC2/BC3/BC7 texture format.
  • both disk stream and on memory stream are supported.
• Lottie (lottie-json .json) format (--features lottie)
  • using rlottie-rs
  • ( supported from bevy_movie_player 0.2.1 or higher )
• Any video format supported by ffmpeg (--features ffmpeg)
  • == WARNING ==: ffmpeg-sys-next needs system ffmpeg libraries installed. This can be hard task for some platforms. For pure Rust solution, I recommend --features gv instead.
  • using video-rs.
  • Currently has extension limitation for bevy-asset-loader. (Need fix here or give options in the future.)
  • ( supported from bevy_movie_player 0.4.2 or higher )

Version compatibility

Known issues

• Movie loading FPS limitation is needed. (example code has 60fps limitation by FixedUpdate)

• Slower FPS on debug build. Please use --release flag to check the performance.

  • or set below in your Cargo.toml

    [profile.dev]
    opt-level = 1
    
    [profile.dev.package."*"]
    opt-level = 3
    

• Compressed Texture cannot be used on first frame, to avoid panic: Using pixel_size for compressed textures is invalid (bevy_render-0.12.1/src/texture/image.rs:785:18).

• No audio support now.

--feature ffmpeg

• Converting frame into BGRA without no hardware acceleration.

Planning

• auto image handling / updating (just play/stop, and eliminate update() also?)
• pure rust based other codec support.
