It's the bigest change yet in 68 | the projects short lived 2.5 year history.

It 2 | does so by creating over 1,000 `metalinks`_ of TED talks varying in both the 3 | quality levels and possible talk groupings by directory. Features include: 4 | 5 | * Creates talks with informative file names - i.e. 6 | ``Unconventional Explanations/Hans Rosling on HIV - New facts and stunning data visuals.mp4`` 7 | instead of original ``HansRosling_2009_480.mp4``. 8 | 9 | * Provides subtitles for talks in over 85 supported languages. New 10 | languages and translations are added daily through the 11 | `TED Open Translation Project`_, and you help out by 12 | `becoming a translator today`_. 13 | 14 | * Tries hard to get all of the talks, or at least most of them - with a good 15 | reason if some have failed. 16 | 17 | * More choice - creates one metalink per available quality level 18 | (currently low, standard and high). 19 | 20 | * More choice - creates one metalink per available talk grouping, with all 21 | talks belonging to the same group placed inside a common directory. The 22 | possible talk groupings are extracted from talks metadata (currently 23 | filming year, publishing year, event name and author). 24 | 25 | * Aggressive caching throughout the project, to avoid expensive network/CPU 26 | operations as much as possible. Proper cache invalidation included. 27 | 28 | * High levels of fault tolerance. 29 | 30 | * Simple, yet powerful homegrown web crawler. 31 | 32 | * Flexible and extensible software design with changes in mind. 33 | 34 | * Provides both the console script and a public API. 35 | 36 | .. _becoming a translator today: http://www.ted.com/translate/forted 37 | .. _metalinks: http://en.wikipedia.org/wiki/Metalink 38 | .. _TED talks: http://www.ted.com/ 39 | .. _TED Open Translation Project: http://www.ted.com/pages/view/id/287 40 | 41 | Downloading TED talks 42 | ===================== 43 | 44 | If you just want to `download TED talks`_, you don't need to install this 45 | package, or even Python. All you need to do is get a 46 | `download client that supports the Metalink standard`_ and choose one of the 47 | `daily updated metalinks`_. 48 | 49 | .. _download TED talks: http://metated.petarmaric.com/ 50 | .. _download client that supports the Metalink standard: 51 | http://en.wikipedia.org/wiki/Metalink#Client_programs 52 | .. _daily updated metalinks: http://metated.petarmaric.com/ 53 | 54 | Installing and running metaTED 55 | ============================== 56 | 57 | You can install metaTED with `pip`_ via ``pip install metaTED``. You can run it 58 | with ``metaTED``, or ``metaTED -h`` to get help and the list of all available 59 | options. 60 | 61 | The project itself is `hosted on bitbucket`_, from where you can get the code 62 | and report bugs. 63 | 64 | .. _pip: http://pip.openplans.org/ 65 | .. _hosted on bitbucket: http://bitbucket.org/petar/metated/ 66 | 67 | New in metaTED 2.1.0 68 | ==================== 69 | 70 | Feature additions 71 | ----------------- 72 | 73 | * Fixed #13, #14: Switched to hard subtitled video download URLs, as there 74 | have been issues with externally hosted soft subtitles.
