Struct re_renderer::video::chunk_decoder::VideoChunkDecoder

pub struct VideoChunkDecoder {
    decoder: Box<dyn AsyncDecoder>,
    decoder_output: Arc<Mutex<DecoderOutput>>,
}

Internal implementation detail of the super::player::VideoPlayer.

Fields

decoder: Box<dyn AsyncDecoder>

decoder_output: Arc<Mutex<DecoderOutput>>

Implementations

impl VideoChunkDecoder

pub fn new( debug_name: String, make_decoder: impl FnOnce(Box<dyn Fn(Result<Frame>) + Send + Sync>) -> Result<Box<dyn AsyncDecoder>> ) -> Result<Self, VideoPlayerError>

pub fn decode(&mut self, chunk: Chunk) -> Result<(), VideoPlayerError>

Start decoding the given chunk.

pub fn end_of_video(&mut self) -> Result<(), VideoPlayerError>

Called after submitting the last chunk.

Should flush all pending frames.

pub fn update_video_texture( &mut self, render_ctx: &RenderContext, video_texture: &mut VideoTexture, presentation_timestamp: Time ) -> Result<(), VideoPlayerError>

Get the latest decoded frame at the given time and copy it to the given texture.

Drop all earlier frames to save memory.

Returns VideoPlayerError::EmptyBuffer if the internal buffer is empty, which it is just after startup or after a call to Self::reset.

pub fn reset(&mut self) -> Result<(), VideoPlayerError>

Reset the video decoder and discard all frames.

pub fn take_error(&mut self) -> Option<TimedDecodingError>

Return and clear the latest error that happened during decoding.
