python - 是否可以在 Phonon 中播放 FLAC 文件？

Question

我正在尝试使用 PySide 的 Phonon 模块播放一些 .flac 文件(在 Mac 上如果它有所不同)但它不是可用于播放的 mimetype。有没有办法启用这个或我需要安装的插件？

您可以使用 Pydub 播放所有流行的音频格式，包括 flac和 Pyaudio

示例代码:

#-*- coding: utf-8 -*-
from pydub import AudioSegment
from pydub.utils import make_chunks
from pyaudio import PyAudio
from threading import Thread


class Song(Thread):

    def __init__(self, f, *args, **kwargs):
        self.seg = AudioSegment.from_file(f)
        self.__is_paused = True
        self.p = PyAudio()
        print self.seg.frame_rate
        Thread.__init__(self, *args, **kwargs)
        self.start()

    def pause(self):
        self.__is_paused = True

    def play(self):
        self.__is_paused = False

    def __get_stream(self):
        return self.p.open(format=self.p.get_format_from_width(self.seg.sample_width),
                           channels=self.seg.channels,
                           rate=self.seg.frame_rate,
                           output=True)

    def run(self):
        stream = self.__get_stream()
        chunk_count = 0
        chunks = make_chunks(self.seg, 100)
        while chunk_count <= len(chunks):
            if not self.__is_paused:
                data = (chunks[chunk_count])._data
                chunk_count += 1
            else:
                free = stream.get_write_available()
                data = chr(0)*free
            stream.write(data)

        stream.stop_stream()
        self.p.terminate()

song = Song("song.flac")
song.play()
