Can't download music video?

[weeee9]

Hi, I've found that when download a music video it will get the error: error parsing signature tokens
but there's no error when it's not a muisc video.

Is the google api changed or something?

I'm using v2.0.1 btw.

I think it has, I've just found this error. I was looking at the functions, I think the decipher.go file will need to be updated. From what I can see, its deciphering methodology may have changed, the JSON response doesn't always contain a url for formats (qualities) to download. If it doesn't, it needs to be extracted. A nice JSON response would look like this:

"streamingData": {
        "expiresInSeconds": "21540",
        "formats": [
            {
                "itag": 18,
                "url": "https://r4---sn-aigl6n7s.googlevideo.com/videoplayback?e.....",
            },

But sometimes it contains a key signatureCipher instead, and there's a url encoded in there. If nobody else has any idea how to update it I might try, but right now I'm focusing on Playlists.

Hi @weeee9 and @clr1107 ,

thanks for the issue, we will try to solve it as soon as possible.

It looks like google add additional data property for embedded video player page, so the regex became invalid.
this should be fixed by #106
if any issue, please feel free to reopen this issue for v2.0.1

release v2.0.2 for this fix
