Properties

`Protected`_header

_header: Id3v2FrameHeader

The parsed frame header, containing the frame ID, size, and flags.

Accessors

frameId

get frameId(): ByteVector
Gets the frame identifier from the header.

Returns ByteVector
Inherited from Id3v2Frame.frameId
- Defined in mpeg/id3v2/id3v2Frame.ts:361

get header(): Id3v2FrameHeader
Gets the frame's header object.

Returns Id3v2FrameHeader
Inherited from Id3v2Frame.header
- Defined in mpeg/id3v2/id3v2Frame.ts:371

size

get size(): number
Gets the payload size in bytes from the header.

Returns number
Inherited from Id3v2Frame.size
- Defined in mpeg/id3v2/id3v2Frame.ts:366

Methods

`Protected`parseFields

parseFields(_data: ByteVector, _version: number): void
No fields to parse; the payload is ignored.
Parameters
- _data: ByteVector
  Raw field bytes (ignored).
- _version: number
  ID3v2 version (ignored).
Returns void
Overrides Id3v2Frame.parseFields
- Defined in mpeg/id3v2/frames/podcastFrame.ts:49

render

render(version?: number): ByteVector
Render the complete frame (header + fields) for the given version.
Parameters
- Optionalversion: number
Returns ByteVector
Inherited from Id3v2Frame.render
- Defined in mpeg/id3v2/id3v2Frame.ts:376

`Protected`renderFields

renderFields(_version: number): ByteVector
Serialises the frame as a fixed 4-byte zero-filled payload.
Parameters
- _version: number
  ID3v2 version (ignored).
Returns ByteVector
Always returns a 4-byte zero-filled ByteVector.
Overrides Id3v2Frame.renderFields
- Defined in mpeg/id3v2/frames/podcastFrame.ts:58

toString

toString(): string
Returns the frame identifier string.

Returns string
The string "PCST".

`Protected` `Static`fieldData

fieldData(
    frameData: ByteVector,
    header: Id3v2FrameHeader,
    version: number,
): ByteVector
Extract the raw field data from a complete frame blob.

This handles unsynchronisation decoding, data-length indicators, and (stubbed) decompression.
Parameters
- frameData: ByteVector
- header: Id3v2FrameHeader
- version: number
Returns ByteVector
Inherited from Id3v2Frame.fieldData
- Defined in mpeg/id3v2/id3v2Frame.ts:406

`Static`fromData

fromData(
    data: ByteVector,
    header: Id3v2FrameHeader,
    version: number,
): PodcastFrame
Internal
Create from raw frame data.
Parameters
- data: ByteVector
- header: Id3v2FrameHeader
- version: number
Returns PodcastFrame
- Defined in mpeg/id3v2/frames/podcastFrame.ts:30
