Struct StreamCopyTrimmer 

pub struct StreamCopyTrimmer { /* private fields */ }

Trim a media file to a time range using stream copy (no re-encode).

Uses avformat_seek_file to seek to the start point, then copies packets until the presentation timestamp exceeds the end point. All streams (video, audio, subtitles) are copied verbatim from the input.

Example

use ff_encode::StreamCopyTrimmer;

StreamCopyTrimmer::new("input.mp4", 2.0, 7.0, "output.mp4")
    .run()?;

Implementations

impl StreamCopyTrimmer

pub fn new( input: impl Into<PathBuf>, start_sec: f64, end_sec: f64, output: impl Into<PathBuf>, ) -> Self

Create a new StreamCopyTrimmer.

start_sec and end_sec are absolute timestamps in seconds measured from the start of the source file. run returns EncodeError::InvalidConfig if start_sec >= end_sec.

pub fn run(self) -> Result<(), EncodeError>

Execute the trim operation.

Errors

• EncodeError::InvalidConfig if start_sec >= end_sec.
• EncodeError::Ffmpeg if any FFmpeg API call fails.
