GstAutoplug Automatically create and connect elements GstAutoplug is an abstract class that is used for constructing and connecting elements. Two types of autopluggers exist: renderer ones and non renderer ones. the renderer autopluggers will not have any src pads while the non renderer ones do. You first need to create a suitable autoplugger with gst_autoplugfactory_make() (see #GstAutoplugFactory). The name of the autoplugger must be one of the registered autopluggers (see #GstStaticAutoplug and #GstStaticAutoplugRender). If the autoplugger supports the RENDERER API, use gst_autoplug_to_renderers() call to create a bin that connectes the src caps to the specified rendrer elements. You can then add the bin to a pipeline and run it. GstAutoplug *autoplug; GstElement *element; GstElement *sink; /* create a static autoplugger */ autoplug = gst_autoplugfactory_make ("staticrender"); /* create an osssink */ sink = gst_elementfactory_make ("osssink", "our_sink"); /* create an element that can play audio/mp3 through osssink */ element = gst_autoplug_to_renderers (autoplug, gst_caps_new ( "sink_audio_caps", "audio/mp3", NULL ), sink, NULL); /* add the element to a bin and connect the sink pad */ ... If the autoplugger supports the CAPS API, use gst_autoplug_to_caps() call to connect the src caps to the destination caps. The created bin will have src pads compatible with the provided sink caps. GstAutoplug *autoplug; GstElement *element; /* create a static autoplugger */ autoplug = gst_autoplugfactory_make ("static"); /* create an element that converts audio/mp3 to audio/raw */ element = gst_autoplug_to_caps (autoplug, gst_caps_new ( "sink_audio_caps", "audio/mp3", NULL ), gst_caps_new ( "src_audio_caps", "audio/raw", NULL ), NULL); /* add the element to a bin and connect the src/sink pads */ ... Optionally you can get a notification when a new object is added to the created pipeline with a g_signal_connect to the "new_object" signal. Use the regular gst_object_destroy() call to destroy the autoplugger. #GstStaticAutoplug, #GstStaticAutoplugRender @object: The type of the autoplugger. @GST_AUTOPLUG_TO_CAPS: @GST_AUTOPLUG_TO_RENDERER: @GST_AUTOPLUG_FLAG_LAST: @autoplug: @object: @autoplug: @srccaps: @sinkcaps: @Varargs: @Returns: @autoplug: @srccaps: @target: @Varargs: @Returns:
