• 4 bytes -- first field size (or whole frame for non-interlaced files)
• 4 bytes -- second field size (0 for non-interlaced files)
• 64 bytes -- luma quantisation matrix
• 64 bytes -- chroma quantisation matrix
• N bytes -- first field data
• M bytes -- second field data (if present)

Field data is raw (non-escaped) JPEG data for 4:2:2 subsampling.
