Detailed Description

Functions required to read streams direct and demux inside Kodi.

This part contains at least the functions necessary for addon that have to be supported. This can only be ignored if you use your own demux.

The data loaded by Kodi is then processed in it itself. The source does not matter, only Kodi must be able to process this stream data itself and is therefore limited in some things.

For more complex things, the addon must integrate its own demuxer and, if necessary, even its own codec processing (see Codec).

Note: These are used and must be set by the addon if the INPUTSTREAM_SUPPORTS_IDEMUX is undefined in the capabilities (see GetCapabilities()). Otherwise becomes demuxing used.

Function Documentation

◆ GetBlockSize()

virtual int kodi::addon::CInstanceInputStream::GetBlockSize ( )

inlinevirtual

Obtain the chunk size to use when reading streams.

Returns: Block chunk size

Remarks: Optional and can leaved away or return 0 if this add-on won't provide this function.

◆ LengthStream()

virtual int64_t kodi::addon::CInstanceInputStream::LengthStream ( )

inlinevirtual

The Total length of the stream that's currently being read.

Returns: Length of the stream

Remarks: Optional and can leaved away or return -1 if this add-on won't provide this function.

◆ PositionStream()

virtual int64_t kodi::addon::CInstanceInputStream::PositionStream ( )

inlinevirtual

The position in the stream that's currently being read.

Returns: Stream position

Remarks: Optional and can leaved away or return -1 if this add-on won't provide this function.

◆ ReadStream()

virtual int kodi::addon::CInstanceInputStream::ReadStream	(	uint8_t *	buffer,
		unsigned int	bufferSize )

inlinevirtual

Read from an open stream.

Parameters

[in]	buffer	The buffer to store the data in.
[in]	bufferSize	The amount of bytes to read.

Returns: The amount of bytes that were actually read from the stream.

◆ SeekStream()

virtual int64_t kodi::addon::CInstanceInputStream::SeekStream	(	int64_t	position,
		int	whence = SEEK_SET )

inlinevirtual

Seek in a stream.

Parameters

[in] position The position to seek to

[in]

whence

offset relative to
You can set the value of whence to one of three things:

Value	int	Description
SEEK_SET	`0`	position is relative to the beginning of the file. This is probably what you had in mind anyway, and is the most commonly used value for whence.
SEEK_CUR	`1`	position is relative to the current file pointer position. So, in effect, you can say, "Move to my current position plus 30 bytes," or, "move to my current position minus 20 bytes."
SEEK_END	`2`	position is relative to the end of the file. Just like SEEK_SET except from the other end of the file. Be sure to use negative values for offset if you want to back up from the end of the file, instead of going past the end into oblivion.

Returns: Returns the resulting offset location as measured in bytes from the beginning of the file. On error, the value -1 is returned.

Remarks: Optional and can leaved away or return -1 if this add-on won't provide this function.
