Member Function Documentation

ElementStartNotify()

void shaka::media::MkvWriter::ElementStartNotify ( mkvmuxer::uint64  element_id, mkvmuxer::int64  position  )

override

Element start notification. Called whenever an element identifier is about to be written to the stream. element_id is the element identifier, and position is the location in the WebM stream where the first octet of the element identifier will be written. Note: the |MkvId| enumeration in webmids.hpp defines element values.

Open()

Status shaka::media::MkvWriter::Open

(

const std::string &

name

)

Opens the given file for writing. This MUST be called before any other calls.

Parameters

name	The path to the file to open.

Returns

Whether the operation succeeded.

Definition at line 18 of file mkv_writer.cc.

Position() [1/2]

mkvmuxer::int64 shaka::media::MkvWriter::Position ( ) const

override

Returns

The offset of the output position from the beginning of the output.

Definition at line 76 of file mkv_writer.cc.

Position() [2/2]

mkvmuxer::int32 shaka::media::MkvWriter::Position ( mkvmuxer::int64  position )

override

Set the current File position.

Returns

0 on success.

Definition at line 80 of file mkv_writer.cc.

Seekable()

bool shaka::media::MkvWriter::Seekable ( ) const

override

Returns

true if the writer is seekable.

Definition at line 91 of file mkv_writer.cc.

Write()

mkvmuxer::int32 shaka::media::MkvWriter::Write ( const void *  buf, mkvmuxer::uint32  len  )

override

Writes out len bytes of buf.

Returns

0 on success.

Definition at line 42 of file mkv_writer.cc.

WriteFromFile() [1/2]

int64_t shaka::media::MkvWriter::WriteFromFile

(

File *

source

)

Writes the contents of the given file to this file.

Returns

The number of bytes written; or < 0 on error.

Definition at line 61 of file mkv_writer.cc.

WriteFromFile() [2/2]

int64_t shaka::media::MkvWriter::WriteFromFile	(	File *	source,
		int64_t	max_copy
	)

Writes the contents of the given file to this file, up to a maximum number of bytes. If max_copy is negative, will copy to EOF.

Returns

The number of bytes written; or < 0 on error.
