I want to display other website videos (eg: DailyMotion, Youtube and Vimeo). How can I do this in my HTML code?
I want to use something like this:
<video width="320" height="240" controls="controls">
<source src="movie.mp4" type="video/mp4" />
<source src="movie.ogg" type="video/ogg" />
Your browser does not support the video tag.
</video>
All three sites provide an "Embed this video" (or similar) link near every video they allow to be shared. Use that.
Bypassing their player would be a violation of their terms (as you would be effectively sucking up the bandwidth they pay for without applying their branding / advertising to the video).
Here is a link that discusses all the above videos websites you mentioned.
