<\/p>\nEn este art\u00edculo, exploraremos las capacidades de Azure Video Indexer. Azure Video Indexer es un servicio de Microsoft que permite extraer informaci\u00f3n valiosa de nuestros videos. Es importante destacar que no se trata de un an\u00e1lisis en tiempo real.<\/p>\n
Los videos se pueden enviar mediante la API o directamente desde el Portal. Una vez procesado el video, podemos recuperar toda la informaci\u00f3n extra\u00edda y guardarla en una base de datos. Adem\u00e1s de descargar el JSON, es posible obtener recursos visuales como fotogramas clave y fotos de personas detectadas.<\/p>\n
Hasta aqu\u00ed, podr\u00eda parecer un servicio simple, pero en realidad es un servicio compuesto por muchos otros que tienen la capacidad de extraer informaci\u00f3n tanto del an\u00e1lisis visual como del audio de los videos. Para entender mejor, veamos el diagrama de la cantidad de informaci\u00f3n que se puede extraer.<\/p>\n
<\/p>\n
En el diagrama, podemos ver que hay una separaci\u00f3n de la informaci\u00f3n obtenida por audio y la informaci\u00f3n obtenida por video. Vamos a ver en detalle cada una de ellas.<\/p>\n
Por audio podemos obtener:<\/strong><\/p>\n Por imagen podemos extraer la siguiente informaci\u00f3n:<\/strong><\/p>\n Como puedes ver, este servicio hace uso de muchos otros para obtener toda esta informaci\u00f3n.<\/p>\n Lo puedes probar gratis aqu\u00ed: https:\/\/www.videoindexer.ai\/<\/a><\/p>\n <\/p>\n El reconocimiento facial de personas no conocidas, como en mi caso, requiere permisos especiales.<\/p>\n En mis pruebas, configur\u00e9 para que me detectara a m\u00ed y a Wally, como puedes ver en la captura.<\/p>\n <\/p>\n Hay m\u00e1s cosas interesantes sobre este servicio. Podemos configurar Azure OpenAI para que nos haga un resumen del video. Esta funcionalidad es muy \u00fatil si pensamos en usarla, por ejemplo, para un buscador de videos sobre reuniones. Podemos elegir resumen corto o largo, adem\u00e1s de un tono formal o informal.<\/p>\n <\/p>\n <\/p>\n Toda la informaci\u00f3n devuelta por el servicio (emociones, objetos, transcripciones, etc.) incluye la duraci\u00f3n y las marcas de tiempo de inicio y fin. Cuando la informaci\u00f3n se refiere al mismo objeto o persona, se presenta en un array. Por ejemplo:<\/p>\n <\/p>\n <\/p>\n <\/p>\n Al convertir el JSON devuelto por Azure Video Indexer en clases de C#, obtendr\u00edamos una estructura jer\u00e1rquica, donde ‘RootResponse’ representar\u00eda el nodo ra\u00edz<\/p>\n <\/p>\n <\/p>\n <\/p>\n En futuros art\u00edculos, exploraremos c\u00f3mo utilizar la informaci\u00f3n extra\u00edda por Azure Video Indexer para construir un buscador de videos robusto. Este buscador se basar\u00e1 en Azure AI Search para el almacenamiento y la b\u00fasqueda de datos, Ada 002 para la generaci\u00f3n de vectores sem\u00e1nticos a partir de las transcripciones, y Node.js para el desarrollo del backend.<\/p>\n <\/p>\n Como demostraci\u00f3n temporal de esta prueba de concepto (POC), puedes acceder a una versi\u00f3n funcional en la siguiente URL: https:\/\/buscador-para-videos-ia.azurewebsites.net<\/a> .<\/p>\n <\/p>\n Ten en cuenta que esta POC es provisional y podr\u00eda ser desactivada en cualquier momento.<\/p>\n","protected":false},"excerpt":{"rendered":" En este art\u00edculo, exploraremos las capacidades de Azure Video Indexer.
