Options
The option for the time picture subfilter in version 0.8.6 are the following:
- time-format <string> : Time format string (%Y%m%d %H%M%S) default value: "%Y-%m-%d %H:%M:%S"
- time-x <integer> : X offset default value: -1
- time-y <integer> : Y offset default value: 0
- time-position <integer> { 0, 1, 2, 4, 8, 5, 6, 9, 10 } : Position default value: 9
- time-opacity <integer [0 .. 255]> : Opacity default value: 255
- time-color <integer> { -268435456, 0, 8421504, 12632256, 16777215, 8388608, 16711680, 16711935, 16776960, 8421376, 32768, 32896, 65280, 8388736, 128, 255, 65535 } : Colour(key) default value: 16777215
- time-size <integer> : Font size, pixels default value: -1
Usage
There are two ways to use the time module: over screen output or display; and over transcoded output.
Screen output or display
To overlay the current time over vlc screen output or display, use the --time-? options (where ? means "format," "x", "y" etc; i.e. --time-format).
In this example, the time will be displayed in white on the lower right hand corner of the viewable output of a transcoded stream and sent to a multicast IP address with the associated SAP announce.
% vlc input_stream --sub-filter=time --time-format %Y-%m-%d,%H:%M:%S --time-position 9 --time-color 16777215 --time-size 12 --sout "#transcode{venc=ffmpeg,vcodec=mp4v}:duplicate{dst=display,dst=rtp{mux=ts,dst=239.255.12.42,sdp=sap,name="TestStream"}}"
In this example, the time will be displayed as 2007-6-19,10:09:33. In addition, the time will only be displayed on the visual display of the input_stream. It will not be part of the transcoded output.
Transcoded output
To overlay the current time over the transcoded output, enable the transcode module subpicture filter or sfilter option.
In this example, the time will be displayed in white on the lower right only in the transcoded output.
% vlc input_stream --time-format %Y-%m-%d,%H:%M:%S --time-position 9 --time-color 16777215 --time-size 12 --sout "#transcode{venc=ffmpeg,vcodec=mp4v,sfilter=time}:duplicate{dst=display,dst=rtp{mux=ts,dst=239.255.12.42,sdp=sap,name="TestStream"}}"
Note that this is accomplished by removing the --sub-filter=time command line option and adding the sfilter transcode module option. If the --sub-filter=time is included vlc will overlay the time over the overlay transcode time, essentially overlapping it.
Also note that the --time-? command line options are "global;" i.e., they affect the way the time overlays both the display and the transcoded output.
