The VideoLAN Forums

Hello. Searching on the forums showed up two people asking the same question back in 2005 but no answer

Is it possible to stream the output of a visualization plugin ? I tried something like

vlc --audio-visual=goom --sout="#std" --sout-standard-access=udp --sout-standard-mux=ts --sout-standard-dst=localhost:1234 myfile.mp3

and it doesn't work (using today's trunk checkout). Is there a trick to do it or is it utterly impossible ?

TIA.

I think It is imposible.

As you can read in the documentation:
video filter are not streamed or saved to a file, it's only affect the visualization to the local display

BUT

the new version of subpicture filter can be streamed or saved to a file.

By now, there's only a few of those subpicture filters, but the number will increase by time.

Okay, thanks for the answer.

Hi Vice,

Can you give me more details howto stream visualisations, I'm very interested in that feature. Is this feature possible with VLC 0.8.6c?

Thanks

From his answer, it's clear that this is not a feature. You can't do it. Subpicture filters are useless in this case because they work on an existing video stream...

My fallback is to pre-generate visualization and embed the music in it using pymedia and a home-grown Python binding for Goom, but it doesn't work yet

VLC, have some subpicture filters that you can use in streaming or in saving to a file. Is all in the documentation:
http://www.videolan.org/doc/play-howto/en/ch04.html

Go to the subpicture filter section (part of "Advanced use of filters")

And as I say, there´s only tree (or four if you count mosiac) of it but there's more to come.

Look into Preferences / Video / Subtitles OSD for options and inline help.

P.S.Today, time subfilter have disapeared and more options are added to marquee filter to display time.
