Class Details¶

class GstInsertBin.InsertBin(**kwargs)¶

Bases:: Gst.Bin
Abstract:: No
Structure:: GstInsertBin.InsertBinClass

This element is a Gst.Bin that has a single source and sink pad. It allows the user (the application) to easily add and remove filter-like element (that has a single source and sink pad), to the pipeline while it is running. It features a fully asynchronous API inspired by GLib’s GAsyncResult based APIs.

Each operation (addition or removal) can take a callback, this callback is guaranteed to be called. Unlike GIO, there is no guarantee about where this callback will be called from, it could be called before the action returns or it could be called later from another thread. The signature of this callback GstInsertBin.InsertBinCallback().

Apart from the library API, since 1.24 insertbin can also be found in the registry:

``` C Gst.Element *pipeline, *insertbin, *videoflip;

Gst.init (None, None); pipeline = Gst.parse_launch (“videotestsrc ! insertbin name=i ! autovideosink”, None);

…

insertbin = Gst.Bin.get_by_name (GST_BIN (pipeline), “i”); videoflip = Gst.ElementFactory.make (“videoflip”, None);

…

g_object_set (videoflip, “method”, 1, None); g_signal_emit_by_name (insertbin, “append”, videoflip, None, None);

… ```
