using filter_by option:

Returns : list(list_formats) You can filter the formats according to the itag, adaptive, progressive, fps, quality, only_audio, no_audio. Example:

>>>Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k").formats.filter_by(only_audio=True)

Other options:

>>> yt.first()

Returns the first index of list_formats

>>> yt.last()

Returns the last index of list_formats

Example:

>>> Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k").formats.filter_by(only_audio=True).first()

Downloading a format:

To download a format, .download() function is used. Params : Download takes following parameters. All are optional .download(convert,onprogress,path,file_name)

1. convert takes a string as an argument. It converts the video into the extension you want. Ex: 'webm' -> 'mp3'. [mp4 coming soon]
2. onprogress takes function name as an argument. The function should have three arguments: Ex: def show_progress(Chunk=None,bytes_done=None,total_bytes=None)
3. path takes full path where you want to save file
4. file_name takes name of the file. by default, it is .title of the video. It is then processed to safe_filename to strip any invalid character.

• You can print final filename by using formats.safe_filename() Ex:

>>> filename = Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k").formats.safe_filename()

Working with Playlist

This Class is responsible for:

1. Get list of all the Videos
2. Create Continuation URL if len(videos)>100
3. Get Continuation data and append all the video IDs to IDS variable

Parameters : url: str - URL of the PlayList start- Define start index of Videos end - Defines end index of videos.

Returns : Tuple : All the Video IDs within the Range variable( if Defined)

  >>> from tube_dl import Playlist, Youtube
  >>> pl = Playlist('https://music.youtube.com/playlist?list=PLTy__vzNAW6C6sqmp6ddhsuaLsodKDEt_').videos
  >>> for i in pl:
  >>>   yt = Youtube(f'https://youtube.com/watch?v={i}')
  >>>   yt.formats.first().download()

Captions

Now you can download captions from youtube. Here's the Sample code.

>>> from tube_dl captions import Captions
>>> caption = Captions('url',language='en') # Use Captions('url').caption_details to get list of languages
>>> caption.fetch_captions() #raw xml output of captions
>>> caption.convert_to_srt(path='c://xample_path//',file_name='captions.srt') # Default filename is youtube id and default path is os.getcwd()

Comments

Yes! It's possible. You can also download comments for a youtube video. It's still in beta but works absolutely file. Here's a simple use case of that.

>>> from tube_dl.comments import Comments
>>> comment = Comments('Your Youtube URL').process_comments(count=45) # Don't define count variable to get all the comments.

• Fetching Replies for comments are not available yet. But will be there soon. Feel free to raise issues tickets.

Convert Formats

Converting any format to mp3 and mp4 is easy. Here's how to do it:

converting to mp3

>>> from tube_dl import Youtube, extras
>>> yt = Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k").formats.filter_by(only_audio=True)[0]
>>> b = a.download() #b variable stores the filename and meta(if available) as object of Output class.
>>> extras.Convert(b,'mp3',add_meta=True) #this will convert the format to mp3 and add meta if var add_meta is True

converting to mp4

>>> from tube_dl import Youtube, extras
>>> yt = Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k").formats.filter_by(only_audio=True)[0]
>>> b = a.download() #b variable stores the filename and meta(if available) as object of Output class.
>>> extras.Convert(b,'mp4',kepp_original=True) #this will convert the format to mp4 and add_meta is not available for mp4 files.
#if keep_original is True, previous format will be deleted i.e. the file downloaded

Merging Formats

Please note that the merge should be between an audio and a video file. Merging speed depends on file size and your system processing speed and it completely depends on CPU performance.

>>> from tube_dl import Youtube, extras
>>> yt = Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k")
>>> yt1 = Youtube("https://youtube.com/watch?v=R2j46bHm6zw&list=RDAMVMd4HYhxlsj5k")
>>> video=yt.formats.filter_by(adaptive=True)[0].download()
>>> audio = yt1.formats.filter_by(only_audio=True)[0].download()
>>> extras.Merge(audio=audio,video=video,result='output.mp4',keep_original=False) 

The result variable stores the output filename and if keep_original = False, it will delete the raw files keeping only the output file.

Working with Live Streams

With live streams, few extra options are available apart from the normal functions. As live streams are not static, a streaUrl is provided by youtube in manifest format. Here's how to grab them.

>>> yt = Youtube('https://www.youtube.com/watch?v=U_XkCKlRcGQ')
>>> if yt.is_live==True:
>>> 	print(yt.hlsUrl)
>>> 	print(yt.dashUrl)
