Module mpeg2ts_reader::pes [−] [src]

Support for Packetised Elementary Stream syntax within Transport Stream packet payloads. Elementary streams are split into 'elementary stream packets', which are then further split into the payloads of transport stream packets.

The types here allow the elementary stream to be reconstructed by passing all the extracted peices back to the calling application as they are encountered -- these peices are not reassembled, to avoid the cost of copying of the underlying data.

To receive Elementary Stream data, create an implementation of ElementaryStreamConsumer, and register this with the StreamConstructor object passed to the Demultiplex instance.

Structs

PesHeader	Header at the start of every PES packet.
PesPacketConsumer	Extracts elementary stream data from a series of transport stream packets which are passed one-by-one.
PesParsedContents	Extra data which may optionally be present in the `PesHeader`, potentially including Presentation Timestamp (PTS) and Decode Timestamp (DTS) values.
Timestamp	A 33-bit Elementary Stream timestamp, used to represent PTS and DTS values which may appear in an Elementy Stream header.

Enums

Copyright	Indicates the copyright status of the contents of the Elementary Stream packet.
DataAlignment	Indicates if the start of some 'unit' of Elementary Stream content is immediately at the start of the PES packet payload.
OriginalOrCopy	Indicates weather the contents of the Elementary Stream packet are original or a copy.
PesContents	Either `PesContents::Payload`, when the `PesHeader` has no extra fields, or `PesContents::Parsed`, when the header provides additional optional fields exposed in a `ParsedPesContents` object.
PtsDts
TimestampError	Detail about the formatting problem which prevented a `Timestamp` value being parsed.

Traits

ElementaryStreamConsumer

Trait for types that will receive call-backs as pieces of a specific elementary stream are encounted within a transport stream.
