Detailed Description

The recording player

This class provides the ability to play VDR records. The difference between usual files and VDR recording files is, that recordings are possibly splitted into multiple files. The class will scan those files and tries to dynamically navigate in them like it would do, if it is a single file.

)

[virtual]

Opens the file

Opens the file at the given mode. These can be:

• UPNP_READ, to read from the file
• UPNP_WRITE, to write to the file

Parameters:

mode

The file mode, i.e. one of the following UPNP_READ UPNP_WRITE

Implements cFileHandle.

int cRecordingPlayer::read	(	char *	buf,
		size_t	buflen
	)			[virtual]

Reads from the file a certain amount of bytes and stores them in a buffer

Returns:

returns

• <0, in case of an error
• 0, when reading was successful

Parameters:

	buf	The char buffer
	buflen	The size of the buffer

Implements cFileHandle.

int cRecordingPlayer::seek	(	off_t	offset,
		int	whence
	)			[virtual]

Seeks in the file

Returns:

returns

• <0, in case of an error
• 0, when reading was successful

Parameters:

	offset	The byte offset in the file
	whence	one of the following SEEK_SET, SEEK_CUR, SEEK_END

Implements cFileHandle.

int cRecordingPlayer::write	(	char *	buf,
		size_t	buflen
	)			[virtual]

Writes to the file

Returns:

returns

• <0, in case of an error
• 0, when reading was successful
