autoplay	data-ry-autoplay	This parameter specifies whether the initial video will automatically start to play when the player loads. Supported values are 0 or 1. The default value is 0.
cc_load_policy	data-ry-cc_load_policy	Setting the parameter's value to 1 causes closed captions to be shown by default, even if the user has turned captions off. The default behavior is based on user preference.
color	data-ry-color	This parameter specifies the color that will be used in the player's video progress bar to highlight the amount of the video that the viewer has already seen.
controls	data-ry-controls	This parameter indicates whether the video player controls are displayed
disablekb	data-ry-disablekb	Setting the parameter's value to 1 causes the player to not respond to keyboard controls.
fs	data-ry-fs	Setting this parameter to 0 prevents the fullscreen button from displaying in the player. The default value is 1, which causes the fullscreen button to display.
hl	data-ry-hl	Sets the player's interface language.
iv_load_policy	data-ry-iv_load_policy	Setting the parameter's value to 1 causes video annotations to be shown by default, whereas setting to 3 causes video annotations to not be shown by default. The default value is 1.

modestbranding	data-ry-modestbranding	This parameter lets you use a YouTube player that does not show a YouTube logo. Set the parameter value to 1 to prevent the YouTube logo from displaying in the control bar. Note that a small YouTube text label will still display in the upper-right corner of a paused video when the user's mouse pointer hovers over the player.
playlist	data-ry-playlist	This parameter specifies a comma-separated list of video IDs to play. If you specify a value, the first video that plays will be the VIDEO_ID specified in the URL path, and the videos specified in the playlist parameter will play thereafter.
playsinline	data-ry-playsinline	This parameter controls whether videos play inline or fullscreen in an HTML5 player on iOS.
rel	data-ry-rel	If the rel parameter is set to 0, related videos will come from the same channel as the video that was just played (changing on or after September 25, 2018)
