Python m3u8 parser
Project description
m3u8
Python m3u8 parser.
Documentation
The basic usage is to create a playlist object from uri, file path or directly from a string:
import m3u8
m3u8_obj = m3u8.load('http://videoserver.com/playlist.m3u8') # this could also be an absolute filename
print m3u8_obj.segments
print m3u8_obj.target_duration
# if you already have the content as string, use
m3u8_obj = m3u8.loads('#EXTM3U8 ... etc ... ')
Encryption key
The segments may be encrypted, in this case the key attribute will be an object with all the attributes from #EXT-X-KEY:
method: ex.: “AES-128”
uri: the key uri, ex.: “http://videoserver.com/key.bin”
iv: the initialization vector, if available. Otherwise None.
If no #EXT-X-KEY is found, the key attribute will be None.
Multiple keys are not supported yet (and has a low priority), follow issue 1 for updates.
Variant playlists (variable bitrates)
A playlist can have a list to other playlist files, this is used to represent multiple bitrates videos, and it’s called variant streams. See an example here.
variant_m3u8 = m3u8.loads('#EXTM3U8 ... contains a variant stream ...')
variant_m3u8.is_variant # in this case will be True
for playlist in variant_m3u8.playlists:
playlist.uri
playlist.stream_info.bandwidth
the playlist object used in the for loop above has a few attributes:
uri: the url to the stream
stream_info: a StreamInfo object (actually a namedtuple) with all the attributes available to #EXT-X-STREAM-INF
media: a list of related Media objects with all the attributes available to #EXT-X-MEDIA
playlist_type: the type of the playlist, which can be one of VOD (video on demand) or EVENT
NOTE: the following attributes are not implemented yet, follow issue 4 for updates
alternative_audios: its an empty list, unless it’s a playlist with Alternative audio, in this case it’s a list with Media objects with all the attributes available to #EXT-X-MEDIA
alternative_videos: same as alternative_audios
A variant playlist can also have links to I-frame playlists, which are used to specify where the I-frames are in a video. See Apple’s documentation on 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 ...')
for iframe_playlist in variant_m3u8.iframe_playlists:
iframe_playlist.uri
iframe_playlist.iframe_stream_info.bandwidth
The iframe_playlist object used in the for loop above has a few attributes:
uri: the url to the I-frame playlist
base_uri: the base uri of the variant playlist (if given)
iframe_stream_info: a StreamInfo object (same as a regular playlist)
Running Tests
$ ./runtests
Contributing
All contribution is welcome, but we will merge a pull request if, and only if, it
has tests
follows the code conventions
If 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.
