Question

我尝试使用vGet库，但它返回以下错误：

 import struct
 import math
 import pyaudio
 from itertools import count

 pa = pyaudio.PyAudio()

 FORMAT = pyaudio.paFloat32
 CHANNELS = 1
 RATE = 44100

 OUTPUT_BLOCK_TIME = 0.05
 OUTPUT_FRAMES_PER_BLOCK = int(RATE*OUTPUT_BLOCK_TIME)


 def sine_gen():
     time = 0
     format = "%df" % OUTPUT_FRAMES_PER_BLOCK
     voices = []
     voices.append(lambda sampletime: math.sin(sampletime * math.pi * 2 * 440.0))

     for frame in count():
         block = []
         for i in xrange(OUTPUT_FRAMES_PER_BLOCK):
             sampletime = time + (float(i) / OUTPUT_FRAMES_PER_BLOCK) * OUTPUT_BLOCK_TIME
             sample = sum(voice(sampletime) for voice in voices) / len(voices)
             block.append(sample)
         yield struct.pack(format, *block)
         time += OUTPUT_BLOCK_TIME
         if frame == 20:
             voices.append(
                 lambda sampletime: math.sin(sampletime * math.pi * 2 * 880.0)
             )

 stream = pa.open(format=FORMAT,
     channels=CHANNELS, rate=RATE, output=1)

 for i, block in enumerate(sine_gen()):
     stream.write(block)

是否有任何其他库或任何类型的解决方案可以从youtube下载视频？

Answer 1

YouTube一直在改变它的视频管理方式，而vGet并未经常更新，因此vGet无法从Youtube下载视频。

Java，如何从youtube下载视频，vget替代？
