Struct FfmpegPreviewSpriteCommand 

Source 
pub struct FfmpegPreviewSpriteCommand { /* private fields */ }
Expand description

Seek-preview sprite-mosaic encoder.

Samples one frame per PREVIEW_FRAME_INTERVAL_SECONDS of the recording, letterboxes each into a PREVIEW_CELL_WIDTH×PREVIEW_CELL_HEIGHT cell, and packs them into a single cols×rows JPEG mosaic via FFmpeg’s tile filter. Multi-segment recordings are concatenated first (mirroring FfmpegPosterCommand) so a segment rollover mid-recording does not truncate the mosaic. Best-effort by convention: callers log and ignore failures so a flaky sprite never breaks VOD playback.

Implementations§

Source§

impl FfmpegPreviewSpriteCommand

Source

pub fn new( ffmpeg_bin: impl Into<String>, input_paths: Vec<PathBuf>, output_path: impl Into<PathBuf>, cols: u32, rows: u32, ) -> Self

Build a sprite-mosaic command. cols/rows are clamped to at least 1.

Source

pub fn run(&self) -> Result<u64, MediaError>

Render the sprite-sheet JPEG mosaic and return its size in bytes.

§Errors

Returns an error when there are no source recordings, a source is missing, the output directory or concat list cannot be written, FFmpeg fails, or the output cannot be inspected after a successful run.
