Implementations§

source§

impl Video

source

pub fn load( debug_name: String, data: Arc<VideoData>, decode_settings: DecodeSettings ) -> Video

Loads a video from the given data.

Currently supports the following media types:

  • video/mp4
source

pub fn data(&self) -> &Arc<VideoData>

The video data

source

pub fn width(&self) -> u32

Natural width of the video.

source

pub fn height(&self) -> u32

Natural height of the video.

source

pub fn frame_at( &self, render_context: &RenderContext, player_stream_id: VideoPlayerStreamId, time_since_video_start_in_seconds: f64, video_data: &[u8] ) -> Result<VideoFrameTexture, VideoPlayerError>

Returns a texture with the latest frame at the given time since video start.

If the time is negative, a zeroed texture is returned.

This API is asynchronous, meaning that the decoder may not yet have decoded the frame at the given timestamp. If the frame is not yet available, the returned texture will be empty.

The time is specified in seconds since the start of the video.

source

pub fn purge_unused_decoders(&self, active_frame_idx: u64)

Removes all decoders that have been unused in the last frame.

Decoders are very memory intensive, so they should be cleaned up as soon they’re no longer needed.
