using freeframe effects in a gstreamer pipeline

[minimalniemand]

Hey folks,

after reading this wiki entry: http://gstreamer.freedesktop.org/wiki/PluginsForEditing I remembered, that there is already a set of realtime video filters available as Open Source.

Wouldn't it be nice to be able to use them in gstreamer, for example for editing as the wiki entry suggests? My C-skills are not good enough to do this on my own I'm afraid, but I could imagine to participate in a project to realize this.

Obviously there already is something that does that, so nevermind:

I am to quick with the posting. I apologize for spamming the list, but felt the need to correct my mistake: ffrend was listed falsely on a site, it is not a gstreamer plugin.

Indeed it is not, but it's a great idea to wrap FreeFrame plugins
(which I hadn't heard of until now). Seems this was suggested all the
way back in 2003 on this list [0]. There is the similar frei0r plugin
framework which is already wrapped in a GStreamer plugin. Maybe too
small for a GSoC project?

Not neccesarily. Writing a full fledged wrapper is a bit of work. Do the
freeframe plugins as such built on linux and are they alredy packaged
for major distributions? The project could also include a ffrend clone
using the GStController framework.

 I am afraid they are not entirely built on Linux, but they are Open Source and multi platform. This is what the OS integration part of the sourceforge page (http://freeframe.svn.sourceforge.net/viewvc/freeframe/trunk/docs/specification.html#CHAPLibrary) says:

FreeFrame plugins are distributed and used as compiled shared objects (.so) in Linux, as Bundles in Mac OS X and as Dynamic Link Libraries (.dll) in Windows.

FreeFrame Plugins export a single function: plugMain. This is passed 3 values: a 32-bit function code, a 32-bit input value and a 32-bit instance identifier. It returns a 32-bit output value.
The input values and output values have different types according to the function code. This may be implemented differently on different platforms in different languages, but the format of the values must be consistent.

 

They also don't come with any distribution I know.
