TO BE DONE

M3U Plus and IPTV

The M3U Plus format is a de facto standard for distributing IPTV playlists on the Internet.

The terms IPTV playlist and M3U Plus playlist are generally used interchangeably, but in this repository M3U Plus refers to the data format, while IPTV Playlist refers to playlists in M3U Plus format.

M3U Plus stems from the extended M3U8 format, of which it supports only 2 tags (#EXTM3U and #EXTINF).

The syntax of the #EXTINF tag has been extended for adding extra attributes (e.g., logo, group, language). Unfortunately this has broken the backward compatibility with the original M3U8 standard (as explained in detail here).

This library has been created from scratch to parse and handle the M3U Plus format only. It does not fully support regular M3U8 playlists.

Usage

Load an IPTV Playlist from a file

import ipytv
file = "~/Documents/my_playlist.m3u"
pl = ipytv.playlist.M3UPlaylist.loadf(file)
print(len(pl.list))

Load an IPTV Playlist from a URL

import ipytv
url = "https://iptv-org.github.io/iptv/categories/classic.m3u"
pl = ipytv.playlist.M3UPlaylist.loadu(url)
print(len(pl.list))

Other loading methods

M3U Playlists can be loaded as a string as well as an array with the following methods respectively:

ipytv.playlist.M3UPlaylist.loads(string)
ipytv.playlist.M3UPlaylist.loada(array)

Access the channels in the playlist

Once loaded, the channels in a playlist can be accessed by using the list property:

import ipytv
url = "https://iptv-org.github.io/iptv/categories/classic.m3u"
pl = ipytv.playlist.M3UPlaylist.loadu(url)
firstChannel = pl.list[0]

Access the properties of a channel

The list property of an M3UPlaylist object contains a list of IPTVChannel objects.

An IPTVChannel object has 3 basic properties (url, name and duration) and an optional attributes field.

The attributes property is a dictionary in the format:

{
    "attribute_1_name": "attribute_1_value",
    "attribute_2_name": "attribute_2_value",
    ...
    "attribute_N_name": "attribute_N_value"
}

For example:

from ipytv.channel import IPTVAttr, IPTVChannel

channel = IPTVChannel(
    url="http://myown.link:80/luke/210274/78482",
    name="Rai 1",
    duration=-1,
    attributes={
        IPTVAttr.TVG_ID.value: "Rai 1",
        IPTVAttr.TVG_NAME.value: "Rai 1",
        IPTVAttr.TVG_LOGO.value: "https://static.epg.best/it/RaiUno.it.png",
        IPTVAttr.GROUP_TITLE.value: "RAI"
    }
)
print(channel.name)
print(channel.attributes[IPTVAttr.GROUP_TITLE.value])

The IPTVAttr enum class contains tags that are commonly found in IPT Playlists.

Format considerations

The extensions to the #EXTINF tag introduced by the M3U Plus format have broken the compatibility with the M3U8 format.

This is what a standard #EXTINF row looks like:

#EXTINF:-1,Rai 1

The format is pretty straightforward:

#EXTINF:<duration>,[<title>]

Let's break it down:

1. the #EXTINF: tag
2. the duration of the content (as an integer or float, signed or not)
3. a comma character
4. a title

This is what an #EXTINF row in the M3U Plus format looks like:

#EXTINF:-1 tvg-id="Rai 1" tvg-name="Rai 1" tvg-logo="https://static.epg.best/it/RaiUno.it.png" group-title="RAI",Rai 1

If we break it down, we see that points 3. and 4. have been added (and they break the previous definition for the #EXTINF tag):

1. the #EXTINF: tag
2. the duration of the content (as an integer or float, signed or not)
3. a space
4. a variable-length, space-separated list of attributes
5. a comma character
6. a title

The attributes in point 4 are in the attribute="value" format, where value may also contain non-escaped commas (which really complicates the parsing logic).

It's worth noting that the M3U8 RFC document specifies how attribute lists should be formatted, but the M3U Plus implementation doesn't comply with the standard.

In conclusion, the M3U Plus format with its quirks and idiosyncrasies is hard to read for humans and hard to parse for computers. It's an ugly format, but it's too widespread to be ignored and for Python to lack a parsing library.

On a funny note, this is how the VLC programmers named the parsing function for the IPTV playlists in the M3U Plus format:

static void parseEXTINFIptvDiots( char *psz_string,
                                  char *(*pf_dup)(const char *),
                                  struct entry_meta_s *meta )
