Re: [Libvisual-devel] Documentation for writing application using libvisual

[Dennis S. <den...@gm...>]

Hello Marcel,

Sorry for the late response.

I don't know VDR, but new supported applications are a good-thing[tm]
of course!

You have to decode the audio stream yourself, libvisual only handles raw
data.

That is, raw graphics, raw audio etc etc.

The visualisation is not an mpeg stream, it's a raw image buffer.

Regarding the performance, I think it would be very hard on the system to
realtime reencode libvisual to an mpeg stream, however I can hardly
believe that this is really needed.

Regarding documentation: http://libvisual.sf.net points to a wiki page with
some documentation, and you can generate doxygen docs for libvisual
(install doxygen and type 'doxygen' in the topdir of the package.)

I advice you to check out libvisual-hackground and for the rest use
libvisual-0.4.0 (really, don't use 0.2.0). It might be wise to read through
the
'standalone' dir in libvisual-hackground and try to write a small test
client
yourself so you get a better insight on the system.

Good luck and if you have any questions feel free to ask!

I've seen you joining the irc channel a lot lately, try to hang out a little
longer, sometimes it takes sometime till someone notices your questions.

Cheers,
Dennis
