how to play the music

Hi @Mrithul-E, thanks for opening this issue. I'm assuming you were using either the WEB or WEB_REMIX client to get the above streaming data? If so, YouTube employs a "bot guard" which means the stream is encoded/encrypted in such a way that it makes it hard to extract a usable URL. The community has been really good at reverse engineering the mechanism YouTube uses for this, so it is possible to decode. A few good references for this are yt-dlp and NewPipe.

The easiest solution is usually just to use a non-web client to fetch the streaming urls. For example, if you hit the /player endpoint as IOS or IOS_MUSIC (or ANDROID or ANDROID_MUSIC) you should get streamable URLs.

Hope that helps!

Very thanks!, but I am so late to see this replay from @tombulled ... and now I started using pytube for decrypting the url

we can simply pass the youtube video url to pytube's Youtube() class and access the json return from youtube using streaming_data function inside Youtube class of pytube

eg:

yt=YouTube("https://www.youtube.com/watch?v="+j)
json_respo = yt.streaming_data

The urls stored in json_respo can used straight forward

I cant open the like got from 'IOS or ANDROID_MUSIC`

[tombulled]

I wrote an example script a while back to demo fetching the streaming URLs, for example:

$ python examples/list-streams-for-video.py
[{'approxDurationMs': '212040',
  'averageBitrate': 3024555,
  'bitrate': 4534636,
  'contentLength': '80165852',
  'fps': 25,
  'height': 1080,
  'indexRange': {'end': '1241', 'start': '742'},
  'initRange': {'end': '741', 'start': '0'},
  'itag': 137,
  'lastModified': '1706255300792263',
  'mimeType': 'video/mp4; codecs="avc1.640028"',
  'projectionType': 'RECTANGULAR',
  'quality': 'hd1080',
  'qualityLabel': '1080p',
  'url': '<STREAMABLE URL HERE>',
  'width': 1920},
  ...
]

I've replaced the URL in the above example output with <STREAMABLE URL HERE> as the URL contains information such as the requestor's IP address. You should be able to download these URLs or view them in your browser. Importantly I believe you have to make HTTP requests for these links from the same IP address that requested them, otherwise they will not work
