Struct FfmpegPosterCommand 

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

One-frame poster extraction used to give clip/highlight permalinks a visual unfurl.

Seeks tail_offset_seconds back from end-of-file so the poster always lands inside the captured window regardless of how long the source recording segment is. When multiple segments are provided they are concatenated first so the poster does not degrade to a slice of the freshly-opened segment after a segment rollover. Best-effort by convention: callers log and ignore failures so a flaky poster never demotes an otherwise-good clip.

Implementations§

Source§

impl FfmpegPosterCommand

Source

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

Build a poster-extraction command.

Source

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

Render the poster JPEG 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.
