Implementations§

source§

impl VideoCache

source

pub fn entry( &mut self, debug_name: String, blob_row_id: RowId, video_data: &Blob, media_type: Option<&MediaType>, decode_settings: DecodeSettings ) -> Arc<Result<Video, VideoLoadError>>

Read in some video data and cache the result.

The row_id should be the RowId of the blob. NOTE: videos are never batched atm (they are mono-archetypes), so we don’t need the instance id here.
