Description:

Time is VLC Extension that displays running time on the screen in a playing video.
(Extension script "time_ext.lua" + Interface script "time_intf.lua")
Features:
- supported tags: [E], [Efps], [D], [R], [T], [O], [P], [n], [_];
- 9 possible positions on the screen;
- elapsed time with milliseconds;
- playback speed rate taken into account for duration time;

Time v3.1+ (intf)
Simple instructions:
1) "time_ext.lua" > Copy the VLC Extension Lua script file into \lua\extensions\ folder;
2) "time_intf.lua" > Copy the VLC Interface Lua script file into \lua\intf\ folder;
3) Start the Extension in VLC menu and configure the Time interface to your liking:
- Windows/Linux: "View > Time v3.x (intf)";
- Mac OS: "Vlc > Extensions > Time v3.x (intf)".

Alternative activation of the Interface script:
* The Interface script can be activated from the CLI (batch script or desktop shortcut icon):
vlc.exe --extraintf=luaintf --lua-intf=time_intf
* VLC preferences for automatic activation of the Interface script:
Tools > Preferences > Show settings=All > Interface >
> Main interfaces: Extra interface modules [luaintf]
> Main interfaces > Lua: Lua interface

Lua 5.1! like in VLC-32bit for Windows (later I will fix it for Lua 5.2/5.3)
INSTALLATION location \lua\extensions\ for an Extension script (Create directory if it does not exist! Then Interface script in \lua\intf\):
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
* Windows (current user): %APPDATA%\VLC\lua\extensions\
* Linux (all users): /usr/lib/vlc/lua/extensions/
* Linux (current user): ~/.local/share/vlc/lua/extensions/
* Mac OS X (all users): /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
* Mac OS X (current user): /Users/%your_name%/Library/Application Support/org.videolan.vlc/lua/extensions/

Compiled (.luac) or non-compiled (.lua) Lua scripts work.

Is it possible that when the addon is showing the time , e.g. the elapsed time ([E]), and "Record" is hit (or shirt+r), the time is also displayed in the recorded file?

This is very useful when someone is taking excerpts from a long video file. The excepts will have their time (relative to the original file) within them. VLC does not put the recording time in the filename of the result file, only the system time.

Hi! It is not possible to do it through the Record button. You should stream a transcoded input with Marquee subpicture filter into a file. Please search VLC wiki and forums for more information about Marquee sub filter.

I have been using your patch to show milliseconds on my time, but it seems the displayed times are randomly retrieved.

Are these values supposed to be as precise as possible, or are they estimations with varying precision?

The time is actual playback time returned by VLC. If you pause playing video, then you will see stabile actual time position including milliseconds. Even if it is paused, the value is still being refreshed on the screen. For better stability I programmed the sctipt to perform update of time on the screen approximately 2 times per second. You can try to disable it completely for frequent update of time:Quote:function input_events_handler(var, old, new, data)
-- tt=os.clock()
-- if tt>=(t+.5) then -- OSD update approximately 2 times per second instead of 4-5 times
-- t=tt

...

-- end
end

You should not use os.clock() as the clock() gives the CPU time, which is how much time the thread consumed. This time is a random time depends on how much the program use the CPU. That's why the update jump up and down randomly. And elapse more than a few seconds.

You should use os.time() here with ">".

tt = os.time()
if tt > t then
....

unfortunately, lua has no built in function to retreived time more acturate than 1 sec.

Also the vlc.osd.message should have a durantion value bigger than 1.5 seconds to keep the OSD shows up all the time:

vlc.osd.message(osd_output, channel1, osd_position, 1500000)

Since vlc itself provide some more precise time value, we can use it here like:

Quote:
...
ttvlc = vlc.var.get(input, "time")
tt = os.time()
if tt > t || ttvlc >= tvlc + .5 then
tvlc = ttvlc
t = tt
...


That will give us some stable update.

Or you can remove that timing part from the script :) It just reduces a refresh period a bit. The extension seems to work pretty well, so it is not necessary there at all. We cannot talk about precision here. You just see a running time on the screen and if you pause a playing video, then actual time appears.

Well, I tried your fix but, as you said, it only speeds up the updates, it doesn't show many differences in the update procedure:
If, for example, I click on the skip bar on a position, with the the video paused, it shows a given time for a fraction of a second, and then skips forward to a different time.

I have, however, found out something interesting: if I skip the video to exactly the same spot, the frames present the same timestamp every time, but if I skip even a pixel to the left/right of that spot, the timestamp of the frame changes.

Could this be a problem calculating the time from the frame numbers? Could the frame numbers themselves be computed wrong when I skip the video (and hence, influence the ms values)?

VLC is time-based player. Every change in position iniciates some internal decoding procedures causing various events. The extension just reads actual available value of elapsed time several times per second, so VLC is not automatically sending any change of time value to extension. If the played media is of constant bitrate, then it si possible to convert time to frames (seconds * fps = frames). Then there is also some rounding of a result (math.floor()). If it is not accurate enough, then I am sorry but I cannot do much about it.

Hi mederi,
I'm using the Time addon following instructions to downgrade my version, and I'm happy to be using it. But I have also noticed that the milliseconds change in strange ways. For example, if I am paused and I change the playback speed from 0.33x to 0.50x. Also, the time displayed does not always land on the same milliseconds each time I pause on the same frame. It's usually close each time, but it does make me wonder how it is being calculated. I wonder, as you suggest, can the frame rate be used to calculate the decimals displayed, such as 30 frames/sec displays hh:mm:ss.000, .033, .067, .100, .133, and so on? If these times were assigned to frames and did not change it would remove some ambiguity in the time.
I really don't need accuracy to the millisecond, but CONSISTENCY to the hundredth of a second would give me confidence to know exactly which frame I'm on. I'm no coder, so I don't know how feasible it is what I'm asking for.

I am not VLC developer. The Extension just works with time values provided by VLC.

Well, I managed a workaround for this, by using AviDemux, and works perfect. Anyone looking for this feature be sure to check it out.

May I know the setting to show the time only in seconds?
Because to create custom playlist it requires time only in seconds. If it could get the time in seconds, the process can be make little bit faster.

Please read carefully my posts above here to add some extra lines of code in the script. Then [E1] tag will be elapsed time in seconds. To edit the script you can use simple text editor like Notepad in Windows, but I recommend you to use Notepad++ that you can find on Internet.

Good...
How can display the play time of video/music file on the screen in the format of Elapsed/Remaining/Total.
And have to adjust the display font and its size.
Is it possible?

Please, press HELP button and read red and yellow parts.
Then just write some new time pattern "[E]/[R]/[D]" or just edit the predefined one. You can also edit the extension script to add some new predefined pattern in the drop-down list and/or to set your favourite pattern as the default one.
To change the look of time, change subtitle settings in VLC preferences.
This extension shows time in a played video. Some future version of this extension can show time also for music files in the dialog box as a video is not available.

This currently does not seem to display more info than the stock VLC GUI already displays.. in order to be more useful, the user should be able to select fractional time display, or frames.

(for example 00:01.83, or 55 frames, and so on)

Thank you for your ideas. I would like to publish your instructions how to alter the script to see elapsed time with miliseconds:
Quote:- remove the math.floor() from the elapsedSecond definition (line 91)
- change the elapsed_time string format to "%02d:%02d:%06.3f" (line 115)

for people that are not programmers like me and need explicit instructions... change line 91 to

Quote:local elapsedSecond = elapsed_time % 60

For most jobs with video material, just the frame- number would be just as helpful.

Meanwhile here is a patch for extended [E] tag for manual input of constant fps information to convert time to frames, e.g. [E23.976]. Tip: [E1] means time in seconds.
There is also a new tag [N] - new/next line.
- insert following line before line 115>local elapsed_time = string.format(... Quote:local et = elapsed_time- insert following lines right before line 125>return osd_output Quote:local osd_output = string.gsub(osd_output, "%[N%]", "\n")
local fps=tonumber(string.match(osd_output,"%[E(.-)%]"))
if fps~=nil then osd_output = string.gsub(osd_output, "%[E.-%]", math.floor(et * fps)) end

[PLD] tag added by Ashada:

Playlist handling often cause crash of VLC for example if you add fresh files into playlist while the extension is active. Total playlist duration would also need total elapsed time.
