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:

Attribute	Filter Keyword	Comments
album	MEDIA_ALBUM	Get from metadata if exist.
artist	MEDIA_ARTIST	Get from metadata if exist.
album_artist	MEDIA_ALBUM_ARTIST	Get from metadata if exist.
genre	MEDIA_GENRE	Get from metadata if exist.
composer	MEDIA_COMPOSER	Get from metadata if exist.
year	MEDIA_YEAR	Get from metadata if exist.
recorded_date	MEDIA_RECORDED_DATE	Get from metadata if exist. if not, same as modified time.
copyright		Get from metadata if exist.
track_num	MEDIA_TRACK_NUM	Get from metadata if exist.
bit_rate		Bitrate
bitpersample		Bit per sample
sample_rate		Samplerate
channel		Channel
duration	MEDIA_DURATION	Duration
rating		Get from metadata if exist.
rotation		Video rotation
width	MEDIA_WIDTH	Width
height	MEDIA_HEIGHT	Height
longitude	MEDIA_LONGITUDE	Get from metadata if exist.
latitude	MEDIA_LATITUDE	Get from metadata if exist.
altitude	MEDIA_ALTITUDE	Get from metadata if exist.
is_360_content	MEDIA_360	Whether 360 content or not.

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.
