Description

Methods

Public constructor Create(reader: unaBitReader_abstract);

Creates a demuxer, prividing a reader for it.

Public destructor Destroy(); override;

Destroys demuxer.

Public function demux(loop, lookupSynch: bool; userData: pointer = nil): bool;

Demux another portion of raw data available in reader.

Parameters
loop
continue demuxing until no more bytes are available in reader
lookupSynch
True = read stream until new sych byte is found, when out of packet's synch; False = fail on first bad synch found
userData
any data to be passed to onDX_payload
Returns

True if demuxing of at least one packet was successfull

Protected procedure onDX_event(PID: TPID; EV: unaMpegTSEvent); virtual;

Override to get events as they appear in stream.

Protected procedure onDX_payload(PID: TPID; data: pointer; len: int; userData: pointer = nil); virtual;

Override to get demuxed payload.

Protected procedure onDX_table(PID: TPID; tableID: TPID); virtual;

Override to get notified about tables.
