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.
