◆ audio_stream_info()

static bool audio_stream_info	(	const std::string &	path,
		BLURAY_STREAM_INFO *	ss,
		int *	channels,
		int *	sample_rate
	)

static

Get information about Blu-ray stream.

Parameters

[in]	path	- Path to Blu-ray disk.
[in]	ss	- BLURAY_STREAM_INFO object.
[out]	channels	- Number of audio channels in stream.
[out]	sample_rate	- Sample rate of stream.

Returns: Returns true if stream has video, false if not.

◆ check_bluray()

int check_bluray	(	const std::string &	path,
		void *	buf = `nullptr`,
		fuse_fill_dir_t	filler = `nullptr`
	)

Get number of titles on Blu-ray.

Parameters

[in]	path	- Path to check
[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)

Note: buf and filler can be nullptr. In that case, the call will run faster, so these parameters should only be passed if they are to be filled in.

Returns: -errno or number of titles on Blu-ray.

◆ create_bluray_virtualfile()

static bool create_bluray_virtualfile	(	BLURAY *	bd,
		const BLURAY_TITLE_INFO *	ti,
		const std::string &	path,
		const struct stat *	statbuf,
		void *	buf,
		fuse_fill_dir_t	filler,
		bool	is_main_title,
		bool	full_title,
		uint32_t	title_idx,
		uint32_t	chapter_idx
	)

static

Create a virtual file entry of a Blu-ray chapter or title.

Parameters

[in]	bd	- Blu-ray disk clip info.
[in]	ti	- Blu-ray disk title info.
[in]	path	- Path to check.
[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]	is_main_title	- true if title_idx is the main title
[in]	full_title	- If true, create virtual file of all title. If false, include single chapter only.
[in]	title_idx	- Zero-based title index on Blu-ray
[in]	chapter_idx	- Zero-based chapter index on Blu-ray

Note: buf and filler can be nullptr. In that case the call will run faster, so these parameters should only be passed if to be filled in.

Returns: On error, returns false. On success, returns true.

Todo:: We actually calculate the overall Blu-ray 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.

◆ parse_bluray()

static int parse_bluray	(	const std::string &	path,
		const struct stat *	statbuf,
		void *	buf,
		fuse_fill_dir_t	filler
	)

static

Parse Blu-ray directory and get all Blu-ray titles and chapters as virtual files.

Parameters

[in]	path	- Path to check.
[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)

Returns: On success, returns number of chapters found. On error, returns -errno.

◆ parse_find_best_audio_stream()

static int parse_find_best_audio_stream ( )

static

Find best match audio stream.

Todo:: Returning 0 is not necessarily the best match. Probably better to parse. For "The life of Brian", e.g., this is the Hungarian audio track. No big deal, though, I can recite mostly all dialogs in English and German (and Latin :), but should be fixed anyway.

Returns: Returns index of best match stream.

◆ parse_find_best_video_stream()

static int parse_find_best_video_stream ( )

static

Find best match video stream.

Todo:: Returning 0 is not necessarily the best match. Probably better to parse. Most DVDs contain only one video track anyway, so this does not hurt at the moment.

Returns: Returns index of best match stream.

◆ video_stream_info()

static bool video_stream_info	(	const std::string &	path,
		BLURAY_STREAM_INFO *	ss,
		int *	width,
		int *	height,
		AVRational *	framerate,
		bool *	interleaved
	)

static

Get information about Blu-ray stream.

Parameters

[in]	path	- Path to Blu-ray disk.
[in]	ss	- BLURAY_STREAM_INFO object.
[out]	width	- Width of video stream.
[out]	height	- Height of video stream.
[out]	framerate	- Frame rate of video stream.
[out]	interleaved	- true: video stream is interleaved, false: video stream is not interleaved.

Returns: Returns true if stream has video, false if not.
