== Examples ==

Example command line use '''(VLC 2.0.0 and newer)''':
 % '''vlc --sub-source="marq{marquee=test,color=16776960} somevideo.avi'''
:This example displays yellow ''test'' text in the top left corner of video

Example command line use '''(VLC 0.9.0 - 1.1.13)''':
 % '''vlc --sub-filter "marq{marquee=\$t (\$P%%),color=16776960}:marq{marquee=%H:%M:%S,position=6}" somevideo.avi'''
 % '''vlc --sub-filter 'marq{marquee=$t ($P%%),color=16776960}:marq{marquee=%H:%M:%S,position=6}' somevideo.avi'''
:This command line will show the stream's title ($t) and current position ($P) in the upper left corner and the current time in the upper right corner. Note that we have to escape $ characters when running this from command line in UNIX shells (this is why we use \$ instead of $). The second line uses single quotes to delimit the string so we don't need to escape the $ character.
:On windows the command line would be:
 C:\Program Files\VideoLAN\VLC\>'''vlc.exe --sub-filter=marq{marquee=$t ($P%%),color=16776960}:marq{marquee=%H:%m%s,position=6} somevideo.avi'''

Example command line '''(All versions including VLC 0.8.6d and prior)''':
 % '''vlc --sub-filter=marq --marq-marquee="Obvious Watermark" --marq-position=0 --marq-size=50 --marq-opacity=25 --marq-color=32768 somevideo.avi'''
:This command will show centered transparent green text. Text sized too large to fit the video window will not appear, and may crash VLC.
