Struct AudioReplacement 

pub struct AudioReplacement { /* private fields */ }

Replace a video file’s audio track with audio from a separate source file.

The video bitstream is copied bit-for-bit (no decode/encode cycle). The audio track from audio_input replaces any existing audio in video_input.

Returns EncodeError::MediaOperationFailed when no audio stream is found in audio_input, or no video stream is found in video_input.

Example

use ff_encode::AudioReplacement;

AudioReplacement::new("source.mp4", "new_audio.aac", "output.mp4").run()?;

Implementations

impl AudioReplacement

pub fn new( video_input: impl Into<PathBuf>, audio_input: impl Into<PathBuf>, output: impl Into<PathBuf>, ) -> Self

Create a new AudioReplacement.

• video_input — source file whose video stream is kept.
• audio_input — source file whose first audio stream is used.
• output — path for the combined output file.

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

Execute the audio replacement operation.

Errors

• EncodeError::MediaOperationFailed if video_input has no video stream or audio_input has no audio stream.
• EncodeError::Ffmpeg if any FFmpeg API call fails.
