It appears that google has made changes so that the default action of videos is to autoplay. This is another stupid move on google's part. If you have several videos on the same page, and they are all autoplaying, you have a horrible mess.
One can override the default action with &autoplay=0
The videos already on the site would need that bit added to them. We also need a code change in the scripts so that the control is automatically added to the embed code when a member embeds a youTube video to prevent the videos from autoplaying.
There are two types of video embed. I think the current use for Dolphin 7.1 is to use the iframe embed code.
Let's look at the iframe code for embedding as lifted from YouTube.
<iframe width="640" height="480" src="//www.youtube.com/embed/2y00BWvglJw?rel=0" frameborder="0" allowfullscreen></iframe>
To prevent that video from autoplaying, we need to add &autoplay=0 as illustrated below.
<iframe width="640" height="480" src="//www.youtube.com/embed/2y00BWvglJw?rel=0&autoplay=0" frameborder="0" allowfullscreen></iframe>
For the old embed code it needs to be added in two places as indicated in red:
<object width="640" height="480"><param name="movie" value="//www.youtube.com/v/2y00BWvglJw?hl=en_US&version=3&rel=0&autoplay=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="//www.youtube.com/v/2y00BWvglJw?hl=en_US&version=3&rel=0&autoplay=0" type="application/x-shockwave-flash" width="640" height="480" allowscriptaccess="always" allowfullscreen="true"></embed></object>
Now the question is how to get Dolphin to automatically add the &autoplay=0 to the code when embedding videos in the video section.
