Package: hotstar-m3u8
m3u8Pythonm3u8parser.DocumentationThe basic usage is to create a playlist object from uri, file path or
directly from a string:importm3u8m3u8_obj=m3u8.load('http://videoserver.com/playlist.m3u8')# this could also be an absolute filenameprintm3u8_obj.segmentsprintm3u8_obj.target_duration# if you already have the content as string, usem3u8_obj=m3u8.loads('#EXTM3U8 ... etc ... ')Supported tags#EXT-X-TARGETDURATION#EXT-X-MEDIA-SEQUENCE#EXT-X-DISCONTINUITY-SEQUENCE#EXT-X-PROGRAM-DATE-TIME#EXT-X-MEDIA#EXT-X-PLAYLIST-TYPE#EXT-X-KEY#EXT-X-STREAM-INF#EXT-X-VERSION#EXT-X-ALLOW-CACHE#EXT-X-ENDLIST#EXTINF#EXT-X-I-FRAMES-ONLY#EXT-X-BYTERANGE#EXT-X-I-FRAME-STREAM-INF#EXT-X-DISCONTINUITY#EXT-X-CUE-OUT#EXT-X-CUE-OUT-CONT#EXT-X-CUE-IN#EXT-X-CUE-SPAN#EXT-OATCLS-SCTE35#EXT-X-INDEPENDENT-SEGMENTS#EXT-X-MAP#EXT-X-START#EXT-X-SERVER-CONTROL#EXT-X-PART-INF#EXT-X-PART#EXT-X-RENDITION-REPORT#EXT-X-SKIP#EXT-X-SESSION-DATAEncryption keysThe segments may be or not encrypted. Thekeysattribute list will
be a list  with all the different keys as described with#EXT-X-KEY:Each key has the next properties:method: ex.: “AES-128”uri: the key uri, ex.: “http://videoserver.com/key.bin”iv: the initialization vector, if available. OtherwiseNone.If no#EXT-X-KEYis found, thekeyslist will have a unique elementNone. Multiple keys are supported.If unencrypted and encrypted segments are mixed in the M3U8 file, then the list will contain aNoneelement, with one
or more keys afterwards.To traverse the list of keys available:importm3u8m3u8_obj=m3u8.loads('#EXTM3U8 ... etc ...')len(m3u8_obj.keys)=>returnsthenumberofkeysavailableinthelist(normally1)forkeyinm3u8_obj.keys:ifkey:# First one could be Nonekey.urikey.methodkey.ivGetting segments encrypted with one keyThere are cases where listing segments for a given key is important. It’s possible to
retrieve the list of segments encrypted with one key viaby_keymethod in thesegmentslist.Example of getting the segments with no encryption:importm3u8m3u8_obj=m3u8.loads('#EXTM3U8 ... etc ...')segmk1=m3u8_obj.segments.by_key(None)# Get the list of segments encrypted using last keysegm=m3u8_obj.segments.by_key(m3u8_obj.keys[-1])With this method, is now possible also to change the key from some of the segments programmatically:importm3u8m3u8_obj=m3u8.loads('#EXTM3U8 ... etc ...')# Create a new Key and replace itnew_key=m3u8.Key("AES-128","/encrypted/newkey.bin",None,iv="0xf123ad23f22e441098aa87ee")forsegmentinm3u8_obj.segments.by_key(m3u8_obj.keys[-1]):segm.key=new_key# Remember to sync the key from the list as wellm3u8_obj.keys[-1]=new_keyVariant playlists (variable bitrates)A playlist can have a list to other playlist files, this is used to
represent multiple bitrates videos, and it’s calledvariant streams.
See anexample here.variant_m3u8=m3u8.loads('#EXTM3U8 ... contains a variant stream ...')variant_m3u8.is_variant# in this case will be Trueforplaylistinvariant_m3u8.playlists:playlist.uriplaylist.stream_info.bandwidththe playlist object used in the for loop above has a few attributes:uri: the url to the streamstream_info: aStreamInfoobject (actually a namedtuple) with
all the attributes available to#EXT-X-STREAM-INFmedia: a list of relatedMediaobjects with all the attributes
available to#EXT-X-MEDIAplaylist_type: the type of the playlist, which can be one ofVOD(video on demand) orEVENTNOTE: the following attributes are not implemented yet, followissue 4for updatesalternative_audios: its an empty list, unless it’s a playlist
withAlternative audio, in this case it’s a list withMediaobjects with all the attributes available to#EXT-X-MEDIAalternative_videos: same asalternative_audiosA variant playlist can also have links toI-frame playlists, which are used
to specify where the I-frames are in a video. SeeApple’s documentationon
this for more information. These I-frame playlists can be accessed in a similar
way to regular playlists.variant_m3u8=m3u8.loads('#EXTM3U ... contains a variant stream ...')foriframe_playlistinvariant_m3u8.iframe_playlists:iframe_playlist.uriiframe_playlist.iframe_stream_info.bandwidthThe iframe_playlist object used in the for loop above has a few attributes:uri: the url to the I-frame playlistbase_uri: the base uri of the variant playlist (if given)iframe_stream_info: aStreamInfoobject (same as a regular playlist)Custom tagsQuoting the documentation:Lines that start with the character '#' are either comments or tags.
Tags begin with #EXT.  They are case-sensitive.  All other lines that
begin with '#' are comments and SHOULD be ignored.This library ignores all the non standard tags by default. If you want them to be collected while loading the file content,
you need to pass a function to theload/loadsfunctions, following the example below:importm3u8defget_movie(line,data,lineno):ifline.startswith('#MOVIE-NAME:'):custom_tag=line.split(':')data['movie']=custom_tag[1].strip()m3u8_obj=m3u8.load('http://videoserver.com/playlist.m3u8',custom_tags_parser=get_movie)print(m3u8_obj.data['movie'])#  million dollar babyRunning Tests$./runtestsContributingAll contribution is welcome, but we will merge a pull request if, and only if, ithas testsfollows the code conventionsIf you plan to implement a new feature or something that will take more
than a few minutes, please open an issue to make sure we don’t work on
the same thing.
