This file has all the code we discussed in this and previous sections.1 def constructPipeline(self): 2 self.player = gst.Pipeline() 3 self.filesrc = gst.element_factory_make("filesrc") 4 self.filesrc.set_property("location", 5 "C:/AudioFiles/my_music.mp3") 6 7 self.decodebin = gst.element_factory_make("decodebin", 8 "decodebin") 9 # Connect decodebin signal with a method. 10 # You can move this call to self.connectSignals) 11 self.decodebin.connect("pad_added", 12 self.decodebin_pad_added) 13 14 self.audioconvert = \ 15 gst.element_factory_make("audioconvert", 16 "audioconvert") 17 18 self.audiosink = \ 19 gst.element_factory_make("autoaudiosink", 20 "a_a_sink") 21 22 # Construct the pipeline 23 self.player.add(self.filesrc, self.decodebin, 24 self.audioconvert, self.audiosink) 25 # Link elements in the pipe....
