Member Typedef Documentation

InitCB

typedef base::Callback<void( const std::vector<std::shared_ptr<StreamInfo> >& stream_info)> shaka::media::MediaParser::InitCB

Called upon completion of parser initialization.

Parameters

stream_info

contains the stream info of all the elementary streams within this file.

Definition at line 35 of file media_parser.h.

NewMediaSampleCB

typedef base::Callback<bool(uint32_t track_id, std::shared_ptr<MediaSample> media_sample)> shaka::media::MediaParser::NewMediaSampleCB

Called when a new media sample has been parsed.

Parameters

track_id	is the track id of the new sample.
media_sample	is the new media sample.

Returns

true if the sample is accepted, false if something was wrong with the sample and a parsing error should be signaled.

Definition at line 44 of file media_parser.h.

NewTextSampleCB

typedef base::Callback<bool(uint32_t track_id, std::shared_ptr<TextSample> text_sample)> shaka::media::MediaParser::NewTextSampleCB

Called when a new text sample has been parsed.

Parameters

track_id	is the track id of the new sample.
text_sample	is the new text sample.

Returns

true if the sample is accepted, false if something was wrong with the sample and a parsing error should be signaled.

Definition at line 53 of file media_parser.h.

Member Function Documentation

Flush()

virtual bool shaka::media::MediaParser::Flush ( )

pure virtual

Flush data currently in the parser and put the parser in a state where it can receive data for a new seek point.

Returns

true if successful, false otherwise.

Implemented in shaka::media::wvm::WvmMediaParser, shaka::media::WebMMediaParser, shaka::media::mp4::MP4MediaParser, shaka::media::mp2t::Mp2tMediaParser, and shaka::media::WebVttParser.

Init()

virtual void shaka::media::MediaParser::Init ( const InitCB &  init_cb, const NewMediaSampleCB &  new_media_sample_cb, const NewTextSampleCB &  new_text_sample_cb, KeySource *  decryption_key_source  )

pure virtual

Initialize the parser with necessary callbacks. Must be called before any data is passed to Parse().

Parameters

init_cb	will be called once enough data has been parsed to determine the initial stream configurations.
new_media_sample_cb	will be called each time a new media sample is available from the parser.
new_text_sample_cb	will be called each time a new text sample is available from the parser.
decryption_key_source	the key source to decrypt the frames. May be NULL, and caller retains ownership.

Implemented in shaka::media::wvm::WvmMediaParser, shaka::media::WebVttParser, shaka::media::WebMMediaParser, shaka::media::mp4::MP4MediaParser, and shaka::media::mp2t::Mp2tMediaParser.

Parse()

virtual bool shaka::media::MediaParser::Parse ( const uint8_t *  buf, int  size  )

pure virtual

Should be called when there is new data to parse.

Returns

true if successful.

Implemented in shaka::media::wvm::WvmMediaParser, shaka::media::WebMMediaParser, shaka::media::mp4::MP4MediaParser, shaka::media::mp2t::Mp2tMediaParser, and shaka::media::WebVttParser.
