Python在gst插件中未检测到soundtouch元素(bpmdetect和pitch)
我已经安装了Python在gst插件中未检测到soundtouch元素(bpmdetect和pitch),python,gstreamer,pitch,audio-processing,soundtouch,Python,Gstreamer,Pitch,Audio Processing,Soundtouch,我已经安装了gstreamer,gst插件bad及其python绑定 下面的代码从给定目录中选择一首歌曲并播放 import pygst pygst.require("0.10") import gst import pygtk import gtk import os class Main: def __init__(self): self.pipeline = gst.Pipeline("mypipeline") self.musicFiles =

,gst插件bad
及其python绑定
下面的代码从给定目录中选择一首歌曲并播放
import pygst
pygst.require("0.10")
import gst
import pygtk
import gtk
import os
class Main:
def __init__(self):
self.pipeline = gst.Pipeline("mypipeline")
self.musicFiles = os.listdir("musicFiles")
self.currentSong = self.musicFiles[0]
self.findFile = gst.element_factory_make("filesrc", "file")
self.findFile.set_property("location", "musicFiles/" + self.currentSong)
self.pipeline.add(self.findFile)
self.mad = gst.element_factory_make("mad", "mad")
self.pipeline.add(self.mad)
self.findFile.link(self.mad)
self.audioconvert = gst.element_factory_make("audioconvert", "convert")
self.pipeline.add(self.audioconvert)
self.mad.link(self.audioconvert)

self.pipeline.add(self.sink)
self.audioresample.link(self.sink)
self.pipeline.set_state(gst.STATE_PLAYING)

gtk.main()
但是,当我尝试创建bpmdetect
元素时,它会出现以下错误:

中的其他元素可以毫无问题地创建。只有soundtouch
(bpmdetect
和pitch
)下的两个元素无法创建。帮助?无法帮助解决bpm错误,但您的代码中存在链接错误,函数中从第二行到最后一行调用了错误的元素进行链接。1)尝试使用env.variableGST\u DEBUG=3
或更高版本(最多7行可能是合理的)运行它,您可能会看到它失败的确切位置。2) 运行:gst inspect bpmdetect
