How to use
This plugin supports Audio, Video, YouTube and Vimeo. With local video, it supports Thumbnail and Subtitle.
Create an example article and put the code below:
1. Insert audio file:
{audio <PATH TO FILE>}
Example: {audio media/audio.mp3} or {audio media/audio.ogg}
2. Insert video file
{video <PATH TO FILE>}
Example: {video media/video.mp4} or {video media/video.webm}
To add a subtitle, you need to create a subtitle file (*.vtt) with the same name as the video file and put it in the folder containing that video. Example with video is media/video.mp4, the subtitle file is media/video.vtt.

Do the same with the thumbnail. The image must have a JPG extension (*.jpg). In this example, the thumbnail is media/video.jpg.
3. Insert YouTube video
{youtube <YOUTUBE ID>}
Example: {youtube gdeqbg8QFJM} for video url: https://www.youtube.com/watch?v=gdeqbg8QFJM
4. Insert Vimeo video
{vimeo <VIMEO ID>}
Example: {vimeo 21946320} for video url: https://vimeo.com/21946320
------------
This plugin is a Content type, so if you want to use it for a module, please read this article.
1. The "radio buttons" extra field doesn't transfer the values in the additional field, e.g., "yes" or "no," and only enters certain values into the #__fields_values database.
2. The "textarea" extra field with the "Use editor" option checked converts to "textarea" when it should be "editor."
3. In K2, the extra field group is assigned in the category. In Joomla Articles, the category is assigned in the extra field. It would be nice if this were automatically completed. A checkbox could be added if someone doesn't want this option.
