Añade información a los vídeos con HTML 5 y Popcorn

PopCorn es una iniciativa que añade información extra a los elementos “video” y “audio” de HTML 5, permitiendo a los usuarios mostrar información extra sobre los vídeos, subtitulso, geolocalización....

Para poder mostrar esta información, solo deberemos de añadir en un fichero XML externo toda la información que queremos mostrar y mediante el atributo “data-timeline-sources” de esas etiquetas, mostraremos la información extra del vídeo.

<video width="530px" height="299px" controls="" data-timeline-sources="xml/webMadeMovies.xml">

 <source type="video/ogg; codecs="theora, vorbis" src="wmmjuly6.ogv"></source>

 <source type="video/mp4; codecs="avc1.42E01E, mp4a.40.2" src="wmmjuly6.mp4"></source>

</video>


Un ejemplo del fichero XML que nos podemos encontrar podría ser el siguiente.
