iFrame and video sizes not optimal

[nwebb1]

Great LTI because it adds no-cookie and ?rel=0 so as not display related videos. But it doesn't use the video's optimal resolution, which is available in youtube, so it often displays black bars top and bottom, or chops off part of the video. Using the youtube provided Embed code does use the optimal resolution for iframe and video.

That is our only issue with this LTI. We may decide it is better to use the Google Embed code and add ?rel=0 manually rather than have to adjust the iframe and video height and width manually. Is there any way the LTI could find the optimal resolution and use that instead of the set small, medium and large sizes? Is anyone still supporting this LTI?
