Hi, This is the Media Controller plugin for libv4l. It uses libv4l2 plugin support which is accepted by Hans De Goede, but not yet included in mainline libv4l2: http://www.spinics.net/lists/linux-media/msg32017.html
The plugin allows a traditional v4l2 applications to work with Media Controller framework. The plugin is loaded when application opens /dev/video0 and it configures the media controller and then all ioctl's by the applicatin are handled by the plugin. The plugin implements init, close and ioctl callbacks. The init callback checks it's input file descriptor and if it coresponds to /dev/video0, then the media controller is initialized and appropriate pipeline is created. The close callback deinitializes the pipeline, and closes the media device. The ioctl callback is responsible to handle ioctl calls from application by using the media controller pipeline. The plugin uses media-ctl library for media controller operations: http://git.ideasonboard.org/?p=media-ctl.git;a=summary The plugin is divided in three separate patches: * Media Controller pipelines initialization, configuration and destruction * v4l operations - uses some functionality from the first one * Plugin interface operations (init, close and ioctl) - uses functionality from first two Yordan Kamenov (3): Add files for media controller pipelines Add files for v4l operations Add libv4l2 media controller plugin interface files -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
