FSEQ compression block loading API. More...

This graph shows which files directly or indirectly include this file:

Functions
int	ComBlock_read (struct FC fc, const struct tf_header_t seq, int index, struct fd_list_s *list)
	Reads the given compression block (by index) from the given file controller and decompresses it (if supported).

int	ComBlock_count (struct FC fc, const struct tf_header_t seq)
	Determines the number of compression blocks available within the given sequence file. The FSEQ file header already contains a field, `compressionBlockCount`, that specifies the number of compression blocks, but other encoding programs are known to write additional zero-sized compression blocks to align write operations. This results in a discrepancy between the header field and the actual number of playable blocks in the sequence file.

Function Documentation

◆ ComBlock_count()

int ComBlock_count	(	struct FC *	fc,
		const struct tf_header_t *	seq )

Determines the number of compression blocks available within the given sequence file. The FSEQ file header already contains a field, compressionBlockCount, that specifies the number of compression blocks, but other encoding programs are known to write additional zero-sized compression blocks to align write operations. This results in a discrepancy between the header field and the actual number of playable blocks in the sequence file.

Parameters

fc	target file controller instance
seq	sequence file for file layout information

Returns: the number of compression blocks on success or a negative error code on failure

◆ ComBlock_read()

int ComBlock_read	(	struct FC *	fc,
		const struct tf_header_t *	seq,
		int	index,
		struct fd_list_s *	list )

Reads the given compression block (by index) from the given file controller and decompresses it (if supported).
