Typedefs

typedef struct video_meta_s * video_meta_h
 The structure type for the Video metadata handle.

The Video Metadata API provides functions to get information about video files present in the device.

Required Header

#include <media_content.h>

Overview

The Video Metadata API provides functions to get information about video files present in the device. Following information about video content (video_meta_h )is provided:

  • artist
  • album
  • genre
  • composer
  • year
  • recorded date
  • copyright
  • track number
  • bit rate
  • width
  • height
  • played count
  • played time
  • played position
    and others.

For getting the video handle (video_meta_h) from the media information (media_info_h), call the media_info_get_video() function.
For getting the information related to video files stored in the device call the respective get functions e.g. to get duration of the video file call video_meta_get_duration() function and so on.
When the video handle is no longer needed, it should be destroyed by calling video_meta_destroy() function.
