I am testing out some simple HTML5 code in order to play embedded YouTube videos in a browser. However, some videos (almost exclusively music videos) will not play in the browser. Instead, a error message stating "This video is unavailable appears" (as shown here).
This is the HTML code used to display the video:
<iframe width="560" height="315" src="https://www.youtube.com/embed/oGpFcHTxjZs" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
which is the exact code generated by YouTube when selecting their "Embed" option.
The iframe tag does work for some videos, however, as shown here:
<iframe width="560" height="315" src="https://www.youtube.com/embed/jxvPjuREDpE" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
What is strange is that all types of embedded videos seem to work in an environment such as jsfiddle, but not when loading a separate HTML file into a browser.
A similar issue was asked here: "This video is unavailable" when putting music videos in iFrame , but is only resolved by running an http server, which is a completely new topic to me.
Does anyone know of an HTML/javscript fix to this issue? Thanks in advance.
