Get number of titles on DVD.

Parameters

[in]	path	- Path to check

[in,out]	filler	- Function to add an entry in a readdir() operation (see0

Returns: -errno or number or titles on DVD

		const std::string &	path,
		const struct stat *	statbuf,
		void *	buf,
		fuse_fill_dir_t	filler,

		int	ttnnum,
		int	audio_stream,
		const AUDIO_SETTINGS &	audio_settings,
		const VIDEO_SETTINGS &	video_settings
	)

static

Create a virtual file for a DVD.

Parameters

[in]	vts_file	- Structure defines an IFO file
[in]	path	- Path to DVD files.
[in]	statbuf	- File status structure of original file.
[in,out]	buf	- The buffer passed to the readdir() operation.
[in,out]	filler	- Function to add an entry in a readdir() operation (see https://libfuse.github.io/doxygen/fuse_8h.html#a7dd132de66a5cc2add2a4eff5d435660)
[in]	full_title	- If true, create virtual file of all title. If false, include single chapter only.
[in]	title_idx	- Index of DVD title.
[in]	chapter_idx	- Index of DVD chapter.
[in]	angles	- Number of angles.
[in]	ttnnum	- DVD title number.
[in]	audio_stream	- Audio stream index.
[in]	audio_settings	- Audio stream settings.
[in]	video_settings	- Video stream settings.

Returns: Returns true if successful. Returns false on error.

Todo:: We actually calculate the overall DVD bitrate here, including all audio streams, not just the video bitrate. This should be the video bitrate alone. We should also calculate the audio bitrate for the selected stream.
