Struct Grabber 

pub struct Grabber { /* private fields */ }

Decodes small pictures of one file quickly, for previews such as the seek bar’s hover thumbnail, with pictures no larger than max_side on their long side.

Usable from any thread, but not Send: open it on the thread that uses it.

Implementations

impl Grabber

pub fn open(path: &Path, max_side: u32) -> Result<Grabber>

Opens path for grabbing; fails for anything probe refuses.

pub fn grab(&self, secs: f64) -> Result<Frame>

The picture at secs, scaled down to fit the size given to open. When the system opened the file but can’t decode its pictures (AV1 in an MP4 on a Mac without an AV1 decoder, say), FFmpeg takes over for this and every later picture.
