Description Maciej Katafiasz 2006-10-07 17:15:48 UTC 
Below is a simple PyGst testcase:

from gst import *

pipe = gst_parse_bin_from_description('playbin uri="file:///home/mathrick/Downloads/OST/Haibane Renmei - Blue Flow {single}/03. Aoi Inori.mp3"', False)

bus = pipe.get_bus()
print bus

Replace the uri with something appropriate, and run, it'll print None. Yet the pipeline can be played just fine. The same thing works when playbin is created manually with factory_make().
Comment 1 Tim-Philipp Müller 2006-10-07 18:41:37 UTC 
I don't think this is a bug.

gst_parse_bin_from_description() creates a _bin_, not a pipeline. This bin is meant to be put into another bin or a top-level pipeline. Until then, gst_element_get_bus() on it will return NULL.

Use gst_parse_launch() to get a top-level pipeline with bus (or better, use gst_element_factory_make() to create a playbin element in this case).
