I am adding a video in a Rich Text field through file button in toolbar. I want to play these video in iframe. How can I do this..?
Or is there anyother option or plugin by which I can upload video which and add in richtext filed anywhere I want and show this in iframe on frontend.
If you want to upload and host the video on your site's server, then I would create a field with an Asset field type and restrict the type to Video. Without further details, it's hard to understand why you'd want to handle it within a Rich Text field.
Since you're hosting the video, you don't need an iframe. Just use the HTML5 <video> tag...
{% for video in entry.FIELDNAME %}
<video width="320" height="240" controls>
<source src="{{ video.getUrl }}" type="video/mp4">
</video>
Your servers will be handling the bandwidth for video delivery though; which is why most people post to YouTube or Vimeo and use the iframe to pass it through. To do that, you'd use the include that Brad mentioned.
In your Rich Text field settings, if you select the "Standard" Redactor config that ships with a fresh Craft install (maps to the .json files in craft/config/redactor), it has the "Video" plugin selected by default.
That will add a Video button to your Rich Text field toolbar.
Clicking it will let you embed iframe code that you can output on the front-end of your site.
