/** @mainpage frei0r - a minimalistic plugin API for video effects
|
||||
*
|
||||
* @section sec_intro Introduction
|
||||
*
|
||||
* This is frei0r - a minimalistic plugin API for video effects.
|
||||
*
|
||||
* The main emphasis is on simplicity - there are many different applications
|
||||
* that use video effects, and they all have different requirements regarding
|
||||
* their internal plugin API. And that's why frei0r does not try to be a
|
||||
* one-in-all general video plugin API, but instead an API for the most
|
||||
* common video effects: simple filters, sources and mixers that can be
|
||||
* controlled by parameters.
|
||||
*
|
||||
* It's our hope that this way these simple effects can be shared between
|
||||
* many applications, avoiding their reimplementation by different
|
||||
* projects.
|
||||
*
|
||||
* On the other hand, this is not meant as a competing standard to
|
||||
* more ambitious efforts that try to satisfy the needs of many different
|
||||
* applications and more complex effects.
|
||||
*
|
||||
*
|
||||
* @section sec_overview Overview
|
||||
*
|
||||
* If you are new to frei0r, the best thing is probably to have
|
||||
* a look at the <a href="frei0r_8h-source.html">frei0r header</a>,
|
||||
* which is quite simple.
|
||||
*
|
||||
* After that, you might want to look at the
|
||||
* <a href="frei0r_8h.html">frei0r functions</a> in more detail.
|
||||
*
|
||||
* When developing a new frei0r effect, you have to choose
|
||||
* - which effect type to use (\ref PLUGIN_TYPE),
|
||||
* - which color model to use (\ref COLOR_MODEL), and
|
||||
* - which parameter types (\ref PARAM_TYPE) your effect will support.
|
||||
*
|
||||
* To round things up, you should decide whether your effect should have
|
||||
* an associated icon (\ref icons), and where it will be installed
|
||||
* (\ref pluglocations).
|
||||
*
|
||||
* @section sec_changes Changes
|
||||
*
|
||||
* @subsection sec_changes_1_0_1_1 From frei0r 1.0 to frei0r 1.1
|
||||
*
|
||||
* - added specifications for plugin locations
|
||||
* - added specifications for frei0r icons
|
||||
* - added RGBA8888 color model
|
||||
* - added packed32 color model
|
||||
* - added better specification of color models
|
||||
* - added string type
|
||||
* - added bounds to resolution (8 <= width, height <= 2048)
|
||||
* - width and height must be an integer multiple of 8
|
||||
* - frame data must be 16 byte aligned
|
||||
* - improved update specification (must not change parameters,
|
||||
* must restore fpu state)
|
||||
* - added note for applications to ignore effects with unknown fields
|
||||
* - added new plugin types mixer2 and mixer3
|
||||
* - added section about \ref concurrency

/**
|
||||
* \addtogroup pluglocations Plugin Locations
|
||||
* @section sec_pluglocations Plugin Locations
|
||||
*
|
||||
* For Unix platforms there are rules for the location of frei0r plugins.
|
||||
*
|
||||
* frei0r 1.x plugin files should be located in
|
||||
*
|
||||
* - (1) /usr/lib/frei0r-1/\<vendor\>
|
||||
* - (2) /usr/local/lib/frei0r-1/\<vendor\>
|
||||
* - (3) $HOME/.frei0r-1/lib/\<vendor\>
|
||||
*
|
||||
* Examples:
|
||||
*
|
||||
* - /usr/lib/frei0r-1/mob/flippo.so
|
||||
* - /usr/lib/frei0r-1/drone/flippo.so
|
||||
* - /usr/local/lib/frei0r-1/gephex/coma/invert0r.so
|
||||
* - /home/martin/.frei0r-1/lib/martin/test.so
|
||||
*
|
||||
* Like in these examples plugins should be placed in "vendor" subdirs
|
||||
* to reduce name clashes.
|
||||
*
|
||||
* @subsection sec_order Plugin Loading Order
|
||||
*
|
||||
* The application shall load plugins in the following order: 3, 2, 1.
|
||||
* If a name clash occurs (two or more frei0r plugins with identical
|
||||
* effect name), the plugins in directory 3 have precedence over plugins
|
||||
* in directory 2, and those in directory 2 have precedence over plugins
|
||||
* in directory 1.
|
||||
*
|
||||
* This makes it possible for users to "override" effects that are
|
||||
* installed in system wide directories by placing plugins in their
|
||||
* home directory.
|
||||
*
|
||||
* The order of loading plugins inside each of the directories
|
||||
* 1, 2, and 3 is not defined.
|
||||

|
||||
|
||||
/**
|
||||
*\addtogroup icons Icons for frei0r effects
|
||||
* @section sec_icons Icons for frei0r effects
|
||||
*
|
||||
* Each frei0r effect can have an associated icon.
|
||||
*
|
||||
* @subsection sec_icon_format Icon Format
|
||||
*
|
||||
* The format of frei0r icons must be png.
|
||||
* Recommended resolution is 64x64.
|
||||
* The icon filename of an effect with effect name "frei0r"
|
||||
* must be "frei0r.png".
|
||||
*
|
||||
* @subsection sec_icon_location Icon location
|
||||
*
|
||||
* The exact location where the application should look for the
|
||||
* plugin is platform dependant.
|
||||
*
|
||||
* For Windows platforms, the icon should be at the same place as
|
||||
* the plugin containing the effect.
|
||||
*
|
||||
* For Unix platforms, the following mapping from plugin location
|
||||
* to icon location must be used:
|
||||
*
|
||||
* Let \<plugin_path\>/\<plugin\> be a frei0r plugin with name \<effect_name\>.
|
||||
* Then the corresponding icon (if any) shall be located in
|
||||
* \<icon_path\>/\<effect_name\>.png.
|
||||
* \<icon_path\> can be obtained in the following way:
|
||||
*
|
||||
* @verbatim
|
||||
<plugin_path> | <icon_path>

@endverbatim

*
|
||||
* (The wildcard '*' stands for any other plugin_path)

||||
*

* For other platforms, no location is defined. We recommend to use the
|

* plugin path where possible.

|

* List of supported color models.
|

*
|
||||
* Note: the color models are endian independent, because the
|
||||
* color components are defined by their positon in memory, not
|
||||
* by their significance in an uint32_t value.
|
||||
*
|
||||
* For effects that work on the color components,
|
||||
* RGBA8888 is the recommended color model for frei0r-1.1 effects.
|
||||
* For effects that only work on pixels, PACKED32 is the recommended
|
||||
* color model since it helps the application to avoid unnecessary
|
||||
* color conversions.
|
||||
*
|
||||
* Effects can choose an appropriate color model, applications must support
|
||||
* all color models and do conversions if necessary. Source effects
|
||||
* must not use the PACKED32 color model because the application must know
|
||||
* in which color model the created framebuffers are represented.
|
||||
*
|
||||
* For each color model, a frame consists of width*height pixels which
|
||||
* are stored row-wise and consecutively in memory. The size of a pixel is
|
||||
* 4 bytes. There is no extra pitch parameter
|
||||
* (i.e. the pitch is simply width*4).
|
||||
*
|
||||
* The following additional constraints must be honored:
|
||||
* - The top-most line of a frame is stored first in memory.
|
||||
* - A frame must be aligned to a 16 byte border in memory.
|
||||
* - The width and height of a frame must be positive
|
||||
* - The width and height of a frame must be integer multiples of 8
|
||||
*
|
||||
* These constraints make sure that each line is stored at an address aligned

||||
* to 16 byte.
