Video Subtitles

Hello,

Ussing AEM 6.1 we would like to upload subtitle files for a video asset uploaded and transcoded with Assets- and DAM workflow.

Example:
The mp4 contains a video stream and audio stream typically with english speaking voice
myVideo_XYZ123.mp4
In order to localice this video we want to upload a set of subtitle files for several many locales (country_language duples)

Canadian french subtitles
myVideo_XYZ123_FR_CA.vtt 
myVideo_XYZ123_EN_CA.vtt 

Spain spanish subtitles
myVideo_XYZ123_ES_ES.vtt 

The subtitle file list list is long but
all subtitle files have same structure

Thanks in advance

Jorge
