Modify the iframe code in order to reproduce a video with the highest definition by default
I have uploaded a video using JW Player. In my JW Player account, under the section "VIDEOS", I click on the "EMBED" blue rectangle, the one that has the "</>" symbols. A screen appears where I can view the "IFRAME" code:
<iframe src="//content.jwplatform.com/players/jIBnkxbm-A91pMc7u.html" width="480" height="270" frameborder="0" scrolling="auto" allowfullscreen></iframe>
I have copied this code to WordPress and the video loads fine.
There is a "HD" button that allows you to choose between different qualities.
Now, every time someone presses play, by default the video is reproduced with the lowest definition.
Pressing this "HD" button, I see that this default definition is "H.264 320 px". If you switch to the highest definition,
the "H.264 1920 px" option, the size of the screen is the same (which is good) and the resolution of the video is enhanced considerably.
Firstly, I would like to modify that code in order that anyone that plays the video,
this is reproduced with the maximum definition, the "H.264 1920 px" option.
Secondly, I would like to modify that code in order that anyone that plays the video,
this is reproduced automatically in "Full Screen Mode".
I would appreciate very much if you could help me to modify the upper "IFRAME" code
in order to achieve these two things.
Thank you very much in advance for your help,
