Demultiplexer

Indication that a header was decoded successfully and there was enough information on how to decode the body of the message.

Upon receiving a result of this type, the demultiplexer will accumulate the number of bits specified by neededBits if that value is defined. If neededBits is undefined, the demultiplexer will accumulate all payload bits until the start of the next message (as indicated by the payload unit start indicator). When accumulation has completed, the specified decoder will be invoked to decode a message.

Error that indicates any data accumulated by the demultiplexer should be dropped and no further decoding should occur until the next payload start.

Stream transducer that converts packets in to sections and PES packets.

The packets may span PID values. De-packetization is performed on each PID and as whole messages are received, reassembled messages are emitted.

PES packets emitted by this method never include parsed headers -- that is, every emitted PES packet is of type PesPacket.WithoutHeader. To get PES packets with parsed headers, use demultiplexWithPesHeaders.

Errors encountered while depacketizing are emitted.

Upon noticing a PID discontinuity, an error is emitted and PID decoding state is discarded, resulting in any in-progress section decoding to be lost for that PID.

Most general way to perform demultiplexing, allowing parsing of arbitrary headers and decoding of a specified output type.

When processing the payload in a packet, the start of the payload is passed along to decodeHeader, which determines how to process the body of the message.

In addition to the payload data, a flag is passed to decodeHeader -- true is passed when the payload data started at byte 0 of the packet and false is passed when the payload data started later in the packet.

See the documentation on DecodeBody for more information.

Variant of demultiplex that allows section and PES decoding to be explicitly specified.

Variant of demultiplex that parses PES packet headers.
