# InputStream Helper #
**script.module.inputstreamhelper** is a simple Kodi module that makes life easier for add-on developers relying on InputStream based add-ons and DRM playback.

## Features ##
- Displays informative dialogs if required InputStream components are unavailable
- Checks if HLS is supported in inputstream.adaptive
- Automatically installs Widevine CDM on supported platforms (optional)
  - Keeps Widevine CDM up-to-date with the latest version available (Kodi 18 and higher)
  - Checks for missing depending libraries by parsing the output from  `ldd` (Linux)

## Example ##

```python
# -*- coding: utf-8 -*-
"""InputStream Helper Demo"""
from __future__ import absolute_import, division, unicode_literals
import sys
import inputstreamhelper
import xbmc
import xbmcgui
import xbmcplugin


PROTOCOL = 'mpd'
DRM = 'com.widevine.alpha'
STREAM_URL = 'https://demo.unified-streaming.com/video/tears-of-steel/tears-of-steel-dash-widevine.ism/.mpd'
MIME_TYPE = 'application/dash+xml'
LICENSE_URL = 'https://widevine-proxy.appspot.com/proxy'
KODI_VERSION_MAJOR = int(xbmc.getInfoLabel('System.BuildVersion').split('.')[0])


def run(addon_url):
    """Run InputStream Helper Demo"""

    # Play video
    if addon_url.endswith('/play'):
        is_helper = inputstreamhelper.Helper(PROTOCOL, drm=DRM)
        if is_helper.check_inputstream():
            play_item = xbmcgui.ListItem(path=STREAM_URL)
            play_item.setContentLookup(False)
            play_item.setMimeType(MIME_TYPE)

            if KODI_VERSION_MAJOR >= 19:
                play_item.setProperty('inputstream', is_helper.inputstream_addon)
            else:
                play_item.setProperty('inputstreamaddon', is_helper.inputstream_addon)

            play_item.setProperty('inputstream.adaptive.manifest_type', PROTOCOL)
            play_item.setProperty('inputstream.adaptive.license_type', DRM)
            play_item.setProperty('inputstream.adaptive.license_key', LICENSE_URL + '||R{SSM}|')
            xbmcplugin.setResolvedUrl(int(sys.argv[1]), True, play_item)

    # Setup menu item
    else:
        xbmcplugin.setContent(int(sys.argv[1]), 'videos')
        list_item = xbmcgui.ListItem(label='InputStream Helper Demo')
        list_item.setProperty('IsPlayable', 'true')
        url = addon_url + '/play'
        xbmcplugin.addDirectoryItem(int(sys.argv[1]), url, list_item)
        xbmcplugin.endOfDirectory(int(sys.argv[1]))

if __name__ == '__main__':
    run(sys.argv[0])
```

The Helper class takes two arguments: protocol (the media streaming protocol) and the optional argument 'drm'.

It is recommended to not add your InputStream add-on as a dependency in addon.xml. It can cause confusion with users not being able to install your add-on because the InputStream add-on is disabled. InputStream Helper addresses issues such as these and helps the user to install/enable required InputStream components.

## Accepted protocol arguments: ##
 * **mpd** -- *MPEG-DASH*
 * **ism** -- *Microsoft Smooth Streaming*
 * **hls** -- *HTTP Live Streaming from Apple*
 * **rtmp** -- *Real-Time Messaging Protocol*

## Accepted drm arguments: ##
 * widevine
 * com.widevine.alpha
