Implementations§

Source§

impl Reader

Source

pub fn new(source: impl Into<Location>) -> Result<Self, Error>

Create a new video file reader on a given source (path, URL, etc.).

§Arguments
  • source - Source to read from.
Source

pub fn read(&mut self, stream_index: usize) -> Result<Packet, Error>

Read a single packet from the source video file.

§Arguments
  • stream_index - Index of stream to read from.
§Example

Read a single packet:

let mut reader = Reader::new(Path::new("my_video.mp4")).unwrap();
let stream = reader.best_video_stream_index().unwrap();
let mut packet = reader.read(stream).unwrap();
Source

pub fn stream_info(&self, stream_index: usize) -> Result<StreamInfo, Error>

Retrieve stream information for a stream. Stream information can be used to set up a corresponding stream for transmuxing or transcoding.

§Arguments
  • stream_index - Index of stream to produce information for.
Source

pub fn seek(&mut self, timestamp_milliseconds: i64) -> Result<(), Error>

Seek in reader. This will change the reader head so that it points to a location within one second of the target timestamp or it will return an error.

§Arguments
  • timestamp_milliseconds - Number of millisecond from start of video to seek to.
Source

pub fn seek_to_frame(&mut self, frame_number: i64) -> Result<(), Error>

Seek to a specific frame in the video stream.

§Arguments
  • frame_number - The frame number to seek to.
Source

pub fn seek_to_start(&mut self) -> Result<(), Error>

Seek to start of reader. This function performs best effort seeking to the start of the file.

Source

pub fn best_video_stream_index(&self) -> Result<usize, Error>

Find the best video stream and return the index.
