pub struct VideoFrameStream { /* private fields */ }

A sequential decoder for file-backed video frames.

This stream decodes frames on demand and can be restarted when playback seeks backward.

pub fn source(&self) -> &MediaSource

Return the source associated with this stream.

pub fn metadata(&self) -> VideoMetadata

Return the decoded video metadata.

pub fn restart(&mut self) -> Result<(), MediaDecodeError>

Restart decoding from the beginning of the media source.
