Time
Starting with VLC media player 0.9.0, the following options specify a character formatted time string, rather than just a plain character string:
- --marq-marquee
- --snapshot-path
- --snapshot-prefix
- --sout-file-format
- --sout-livehttp-index
Time variables are those defined by the strftime C function. The following expansions are most common:
- %Y : year
- %m : month
- %d : day
- %H : hour
- %M : minute
- %S : second
For an extensive list have a look at [1] (or the strftime manual page on Unix systems).
Input meta
VLC-specific meta-data expansions are available for the following options:
- --input-title-format
- --snapshot-path (in version 2.2.0 and later)
- --snapshot-prefix (in version 2.2.0 and later)
The following expansion are performed:
- $a : artist
- $b : album
- $c : copyright
- $d : description
- $e : encoded by
- $f : total decoded frame count (since VLC started)
- $g : genre
- $l : language
- $n : track number
- $o : track total
- $p : now playing
- $r : rating
- $s : subtitles language
- $t : title
- $u : url
- $A : date
- $B : audio bitrate (in kb/s)
- $C : chapter (as in DVD chapter number)
- $D : duration
- $F : full name with path
- $I : title (as in DVD title number)
- $L : time left
- $N : name (media name as seen in the VLC playlist)
- $O : audio language
- $P : position (in %)
- $R : rate
- $S : audio sample rate (in kHz)
- $T : time code of the video
- $U : publisher
- $V : volume
- $Z : now playing (artist - title)
- $_ : new line
- $<any other char> : <any other char> (for example: $$ transforms to $)
You can insert a space between the $ sign and the character to tell it to not display anything if the meta data isn't available. For example: $ T instead will display "" while $T would display "--:--:--", if no time is available. If a time is available, it would display something like "01_22_13" (for a snapshot from one hour, 22 minutes and 13 seconds in a video).
Source code
If you want to know how this works, check out src/text/strings.c (search for vlc_strfinput)
The variable b_empty_if_na refers to the leading space feature: Add option to format strings to prevent displaying dashes if the meta info was unavailable (ie: if time is unavailable, "$T" will display "--:--:--" while "$ T" won't display anything). This is of course completely untested :)
