I'm not sure if perhaps you, and the person working on the part file plugin,
have the same underlying questions.
To get a plugin to be properly seen by VLC:
When you add a module abide to the following.
1: Add the new files to a new target in a Modules.am file. If you create a
new directory (ill advised) you'll need to create a new Modules.am file.
2: add the name of the module (as defined in the Modules.am) to the
configure.ac file BUILTIN_MODULES or something will do.
3: if your module needs any options, these have to be added in the
configure.ac file (see other modules i.e. mkv or something)
4: rerun bootstrap and configure
For example, I wrote the marquee video subfilter, marq.c, found in
In modules/video_filter/modules.am, you will see the line:
SOURCES_marq = marq.c
In configure.ac, up at the top level of the VLC trunk, note that marq is
referenced in the line:
VLC_ADD_PLUGINS([gestures rc telnet hotkeys netsync showintf time marq
podcast shout sap fake])
The plugin, of course, has to follow the right "rules" to make it valid,
useable, by VLC.
For marquee, my prototypes were time.c and logo.c, other filters that did
the same kind of thing I wanted to do. A lot of "gludge", hooks and
handles, are easiest to get by copying from a filter that does something
close to what you intend the new code to do.
