I've looked into it, in order to get the sig part for the audio downloads, we would need to construct/parse an AMF request/response.

@naglis If you need a starting point, I have a partially implemented AMF 0 reader:

import io

from youtube_dl.utils import struct_unpack

class AmfReader(io.BytesIO):

    # Utility functions for reading numbers and strings
    def read_unsigned_long_long(self):
        return struct_unpack('!Q', self.read(8))[0]

    def read_double(self):
        return struct_unpack('!d', self.read(8))[0]

    def read_unsigned_int(self):
        return struct_unpack('!I', self.read(4))[0]

    def read_unsigned_short(self):
        return struct_unpack('!H', self.read(2))[0]

    def read_unsigned_char(self):
        return struct_unpack('!B', self.read(1))[0]

    def read_amf_string(self):
        length = self.read_unsigned_short()
        return self.read(length)

    def read_amf_value(self):
        value_type = self.read_unsigned_char()
        if value_type == 0:  # Double
            return self.read_double()
        if value_type == 2:  # DataString
            return self.read_amf_string()
        elif value_type == 3:  # DataObject
            data_object = {}
            while True:
                marker = tuple(map(lambda _: self.read_unsigned_char(), range(3)))
                if marker == (0, 0, 9):
                    break
                self.seek(-3, io.SEEK_CUR)
                name = self.read_amf_string()
                data = self.read_amf_value()
                data_object[name] = data
            return data_object
        else:
            raise NotImplementedError('Unsupported type %s' % value_type)


# From https://en.wikipedia.org/wiki/Action_Message_Format#AMF0
r = ' 03 00 04 6e 61 6d 65 02 00 04 4d 69 6b 65 00 03 61 67 65 00 40 3e 00 00 00 00 00 00 00 05 61 6c 69 61 73 02 00 04 4d 69 6b 65 00 00 09'

b = eval('b"""' + r.replace(' ', '\\x') + '"""')
reader = AmfReader(b)
print(reader.read_amf_value())

Thanks @jaimeMF, I will definitely check it out.

Hi,

This issue has been solved.Try the following command :
youtube-dl.exe --verbose -x --audio-format mp3 http://www.trilulilu.ro/the-blizzard-yuri-kane-everything-about-you-ft-rel#

Please make sure ffmpeg is install on your system. If not please follow the instructions given here
