Detailed Description

TrickPlayHandler is a single-input-multiple-output media handler. It creates trick play streams from the input.

Member Function Documentation

Status shaka::media::TrickPlayHandler::InitializeInternal ( )

overrideprotectedvirtual

Internal implementation of initialize. Note that it should only initialize the MediaHandler itself. Downstream handlers are handled in Initialize().

Implements shaka::media::MediaHandler.

Definition at line 36 of file trick_play_handler.cc.

Status shaka::media::TrickPlayHandler::Process ( std::unique_ptr< StreamData >  stream_data )

overrideprotectedvirtual

Process the incoming stream data. Note that (1) stream_data.stream_index should be the input stream index; (2) The implementation needs to call DispatchXxx to dispatch the processed stream data to the downstream handlers after finishing processing if needed.

Implements shaka::media::MediaHandler.
