[Libvisual-devel] Minor problems with compilation

[salsaman <sal...@xs...>]

Hi,
I am looking into making a livido wrapper for the libvisual plugins. 
Livido details can be found at http://livido.dyne.org/codedoc/. This 
will be a new open source architecture for video plugins. Once this is 
done, your plugins will be usable in LiVES, Cinelerra, FreeJ, Veejay, 
effecTV and PDP.

I have compiled libvisual, but an error came up in the process. You need 
to add -I . to the include files, as the headers are in . for a new 
build until make install is run.

Tomorrow I will try to build a livido wrapper. This should not be too 
complicated, I will retrieve a list of plugins and each one will become 
a livido_class in the wrapper library. Each class will construct a 
channel template with 0 in channels and one out channel with whatever 
palettes the plugin allows.

Within livido, each livido_class can be used to create any number of 
livido_instances. each instance in this case representing an instance of 
a libvisual plugin.

OK, quick question, are the plugins threadsafe - ie. can I start up 
several instances of different/the same plugin without problem ?

Currently the only problem I forsee is with the size negotiation, I 
understand that libvisual uses horizontal and vertical block size 
restrictions, whereas livido currently only allows a completely free or 
a fixed channel size. I will suggest to the other livido developers that 
we implement something for block sizes.

I hope you are serious about developing this architecture, because this 
could become a very nice addition to the livido plugin set.

Salsaman.
