Methods
parse(datanon-null) → {Array<!shaka.extern.MetadataFrame>}
Parses {@code data} and returns every metadata frame found in it.
Implementations MUST:
- Return an empty array (never {@code null}) when no frames are found or the data is not recognised.
- Not throw; all errors should be swallowed and result in an empty or partial return value.
- Use ID3v2.4 four-character frame IDs as {@code key} values wherever a mapping exists (see class-level documentation).
Parameters:
| Name | Type | Description |
|---|---|---|
data |
Uint8Array | Raw bytes of the media segment or file. |

- Array<!shaka.extern.MetadataFrame>
parseFlacPicture_(blocknon-null) → {shaka.extern.MetadataFrame}
Parse a FLAC PICTURE metadata block (type 6) and return it as an
APIC-equivalent MetadataFrame so that callers can treat album art from
FLAC files the same way they treat ID3v2 APIC frames.
FLAC PICTURE block layout (all fields big-endian):
[0-3] picture type (uint32 BE)
[4-7] MIME length (uint32 BE)
[8 … 8+mimeLen-1] MIME type string (UTF-8)
[8+mimeLen … +3] description length (uint32 BE)
[…+descLen-1] description string (UTF-8)
[… + 4] width (uint32 BE) – ignored
[… + 4] height (uint32 BE) – ignored
[… + 4] color depth (uint32 BE) – ignored
[… + 4] color count (uint32 BE) – ignored
[… + 4] data length (uint32 BE)
[… + dataLen] raw image bytes
Parameters:
| Name | Type | Description |
|---|---|---|
block |
Uint8Array | Raw bytes of the PICTURE metadata block body (i.e. the 4-byte block header has already been stripped). |
