    pub frame_num: u32,
    pub x_offset: u32,
    pub y_offset: u32,

}
Expand description

Metadata for a single frame extracted by the demuxer.

The bitstream field contains the raw VP8 or VP8L data (not including any RIFF container framing). For lossy frames with separate alpha, the alpha_data field contains the raw ALPH chunk payload.

Fields§

§frame_num: u32

1-based frame number.

§x_offset: u32

Horizontal offset of the frame on the canvas (always even).

§y_offset: u32

Vertical offset of the frame on the canvas (always even).

§width: u32

Frame width in pixels.

§height: u32

Frame height in pixels.

§duration_ms: u32

Frame duration in milliseconds.

§dispose: DisposeMethod

How the frame area is disposed after rendering.

§blend: BlendMethod

How the frame is blended onto the canvas.

§has_alpha: bool

Whether the frame contains alpha data.

§is_lossy: bool

Whether the frame uses lossy (VP8) encoding. false means lossless (VP8L).

§bitstream: &'a [u8]

Raw VP8 or VP8L bitstream data for this frame.

§alpha_data: Option<&'a [u8]>

Raw ALPH chunk payload, if present (lossy frames with separate alpha).
