Detailed Description

This file contains functions to detect subtitle files.

Function Documentation

◆ filename_strip_ext_inplace()

static void filename_strip_ext_inplace ( char *  str)
static

Remove file extension in-place.

Referenced by subtitles_Detect().

◆ filename_trim_inplace()

static char * filename_trim_inplace ( char *  str)
static

Trim special characters from a filename.

Trims whitespaces and other non-alphanumeric characters from filenames.

Warning
This function operates on the passed string without copying. It might return a pointer different to the passed one, in case it trims characters at the beginning. Therefore it is essential that the return value is used where the trimmed version of the string is needed and the returned pointer must not be free()d but rather the original pointer!

◆ paths_to_list()

static char ** paths_to_list ( const char *  psz_dir,
char *  psz_path 
)
static

Convert a list of paths separated by ',' to a char**.

◆ slave_strcmp()

static int slave_strcmp ( const void *  a,
const void *  b 
)
static

◆ subtitles_Detect()

int subtitles_Detect ( input_thread_t p_this,
char *  psz_path,
const char *  psz_name_org,
input_item_slave_t ***  ppp_slaves,
int *  p_slaves 
)

Detect subtitle files.

When called this function will split up the psz_name string into a directory, filename and extension. It then opens the directory in which the file resides and tries to find possible matches of subtitles files.

Parameters
p_thisthe calling input_thread_t
psz_patha list of subdirectories (separated by a ',') to look in.
psz_name_orgthe complete filename to base the search on.
ppp_slavesan initialized input item slave list to append detected subtitles to
p_slavespointer to the size of the slave list
Returns
VLC_SUCCESS if ok
