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 |
title | MEDIA_TITLE | Get from metadata if exist. if not, base name except file extension. |
album | MEDIA_ALBUM | Get from metadata if exist. |
artist | MEDIA_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 | MEDIA_COPYRIGHT | Get from metadata if exist. |
track_num | MEDIA_TRACK_NUM | Get from metadata if exist. |
bit_rate | MEDIA_BITRATE | Bitrate |
bitpersample | MEDIA_BITPERSAMPLE | Bit per sample |
sample_rate | MEDIA_SAMPLERATE | Samplerate |
channel | MEDIA_CHANNEL | Channel |
duration | MEDIA_DURATION | Duration |
rating | MEDIA_RATING | Get from metadata if exist. |
author | MEDIA_AUTHOR | Get from metadata if exist. |
rotation | MEDIA_ORIENTATION | Video rotation |

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.
