YouTube Widgets?. there are alt of them. YouTube Showcase Widgets?. there are some of them. YouTube Showcase Widgets with a built in player?. those can be counted with one hand. here is one that works, looks good and is simple. it is called YouEmbedTube.
YouEmbedTube is a YouTube Widget Showcase Widget Player. so it showcases videos and plays them without leaving the page. sure you can search and browse around videos in a YouTube Embed now. but this displays them better and lets you display the Videos you are interested in without having to put several embeds in the same page.
You only need to go to the YouEmbedTube web page. set for youtube video tag query. select how many videos you are interested in showcase in your query and call a for preview.
This will call for videos that are matched to the tag or tags you searched for and it will show the number of videos you set for it. all while display it deep in carrousel. inside a simple but ok looking widget.
If a visitor clicks on a video. the video will be called into a built in player without the user having to leave the page. and will also maintain said visitor focused on the video he clicked minimizing distractions.
Good and simply YouTube Widget. it is a Widget service by Quinto Piso from Argentina. the same who developed FlickrIn.
