Struct Jpeg 

pub struct Jpeg {
    pub visual: Visual,
    pub btrt: Option<Btrt>,
    pub colr: Option<Colr>,
    pub pasp: Option<Pasp>,
    pub fiel: Option<Fiel>,
    pub spatial: Option<Box<Spatial>>,
}

Photo - JPEG (‘jpeg’), QuickTime’s Motion JPEG visual sample entry.

Unlike most video codecs, JPEG has no separate decoder configuration box: the quantization/Huffman tables and everything else needed to decode are self-contained within each JPEG-coded sample (baseline JPEG per ITU-T T.81 | ISO/IEC 10918-1, the core JPEG bitstream standard), so this is just a Visual sample entry plus the usual optional extension boxes.

'jpeg' itself is a QuickTime-registered codec, not part of the ISO base media file format – see its MP4RA registration (spec: “QT”) and Apple’s QuickTime documentation on the Photo Compressor, which each sample’s JPEG bitstream conforms to.
