How to flip a video on chrome mobile using css (when in fullscreen mode)?

I'm developing a web app whose main purpose is streaming dancing videos and I'm facing this problem just in chrome mobile, it works flawlessly in firefox mobile, and in every other desktop browser.
The thing is I need to be able to flip an html5 video element and it works... well, it works until I go fullscreen, then it stays for a few seconds and reverts to the original video (not flipped).
I'm using the css "transform: scaleY(-1)" property.
I've tried setting this property to the video tag, to an upper div, within the video tag and the div which requests fullscreen. And to the div requesting the full screen with no success. If I set scale(); to any positive number between 0 and 1, it seems to do the trick but it doesn't work with negative numbers.
I'm aware of the UA css :not(:root):-webkit-full-screen {transform: none !important}, but it doesn't seem to be the problem. I would rather say it's more related to the way chrome handles video in fullscreen mode.
Any help would be appreciated. If I can't make it work, I'll have to provide another stream with the mirrored version of each video.
Thanks in advance, If you need any examples don't hesitate on asking.

Force a div to show up and overlay whatever is in fullscreen

I have a Chrome extension that inserts a menu into the page, but whenever any flash or html5 video player goes full screen, anything outside of the video player is invisible.
Could I have two objects in full screen at the same time (one over the other), or is there another way to do this? I would rather not have to insert the html specifically into different places on different websites, because of the large variety of existing video players. The solution should be universal for all video players.
EDIT:
Since then, a lot of the web has moved to using html5 instead of flash, so this has become a very possible thing to do on almost all websites.
Here was the code I ended up writing and using. Hopefully this will help someone:
document.addEventListener("webkitfullscreenchange", function(){//Whenever an element becomes or stops being in full screen
//first, grab the page's fullscreenElement
var fse = document.fullscreenElement||document.mozFullScreenElement||document.webkitFullscreenElement||document.msFullscreenElement;
if(fse){//if there is a fullscreened element
fse.appendChild(menu);//append the menu inside the fullscreened element
}else{//if nothing is in full screen
if(window.self !== window.top){//if we are in an iframe
menu.remove();//hide menu if we are in an iframe
}else{//if we arn't in an iframe
document.body.insertBefore(menu, document.body.firstChild);//show menu
}
}
});

This is not likely to be possible. The video player fullscreen implementation takes over the entire screen; you do not have a browser window to overlay on anymore.
It's not the same as going fullscreen in your browser, where you still have the normal browser window to work with.
edit: to expand further;
With any video player using Flash, this is absolutely not possible, because you have no chance of any HTML elements to overlay onto; the fullscreen is handled by flash itself, and you can't do anything with that.
With HTML5, from my testing it also seems impossible. I went to this sample page, edited the HTML in the dev tools to try inserting a div inside the video element, but it won't render.
If you had control over the pages, it might be possible to fullscreen a container div instead of the video itself, and then achieve what you want, but since you can't control the pages in question, that likely won't help you at all (unless you wanted to try replacing IDs/etc in-page, but even that wouldn't guarantee success; if the page JS already had handles on the relevant elements, replacing IDs wouldn't update those)

Unfortunately as #Collin Grady mentioned this is not possible since the browser takes care when you play a fullscreen video.
You can still simulate full screen tho! You could modify the size of the video to adjust to the size of the screen (or whatever size you require). By doing this you still have control on your elements and can show your menu on top of the video.
There is an article in CSS Tricks that could guide you on how to modify the dimensions of a youtube video. The writer of the article wrote a jQuery plugin too called FitVids.JS
By Simulating full screen you could show what you want on top.
I hope this helps

Is their any responsive lightbox with slideshow that has proper swipe?

I have been search for hours for a jquery type plugin that is responsive and also has proper swipe animation during gesture.
http://www.photoswipe.com/ is 99% there except that it dosent support single image lightbox mode, its geared towards grouping images into swipable galleries, which it does brilliantly.
However now and then I may want a few images on a page to have no relation to each other. Id rather have a default class, that when used all images opened up in a single image lightbox. Photoswipe automatically groups any images given the same class.
If I was able to set an option with this plugin to hide the prev/next images on a call, then it would have been perfect.
Important though, is that the plugin must use full screen like photoswipe does. So many responsive plugins seem to waiste the screen with unrequired image chrome. The intended slide show or light box should be like viewing a gallery on a smartphone - again photoswipe does this. its only fall back in being able to have non related instances.

There are a couple out there that appear to be inline with what you want. I never understood why some developers create "responsive" galleries, but waste so much space with padding or decretive chrome elements.
I was thinking of using PhotoSwipe, but the developers stopped supporting it and recently threw it out there for the open source community to maintain. Kind of turned me off during the transition.
Here are a few others I came across that I'm considering myself.

Embedding youtube video has scrolling issues on iPhone

When I'm embedding youtube video in my mobile page, it brings a lot of scrolling issues in iPhone(I guess, it will same problems in other devices too). Users just can't scroll page when their tap on the video itself.
Here is code I'm used for embedding
<iframe width="270" height="152" frameborder="0" src="http://www.youtube.com/embed/nBJCbUMHna4?rel=0"></iframe>
Can we solve this problem anyway? For example, can we show only thumbnail image of video and play it when user taps on that image. I think the scrolling problem will disappear when there will be image instead of iframe in the page.
I've tried to use html5 version of youtube video, but seems IPhone still renders video in flash way.
<iframe width="270" height="152" frameborder="0" src="http://www.youtube.com/embed/nBJCbUMHna4?rel=0&html5=True"></iframe>

The below snippet appears to do the trick without any JavaScript trickery. At the same time this also ensures that you get the nice scrolling momentum on iOS.
*{
-webkit-overflow-scrolling: touch;
}

I've exactly the same issue on my site, this is not the case in the google blog.
I precise that it doesn't scroll the iframe content, it scroll the safari's viewport.
I've try to replace the iframe by an img, no scrolling problem but the video now open in the youtube app...
I'm interested by a solution/workaround
for image solution
var frame = $('#youtubeFrame');
if ( mobileCheck )
{
frame.replaceWith('<img id="imgYoutubeFrame"/>');
$.getJSON("http://gdata.youtube.com/feeds/api/videos/"+youtubes[currentVideo]+"?v=2&alt=jsonc&callback=?", function(json){
$("#imgYoutubeFrame").attr("src", json.data.thumbnail.hqDefault);
});
}

We are having this issue with Vimeo on our mobile site as well. It took us a while to even figure out that users were having the issue.
One work around that we are checking out is to add a div layer on top of the video that allows users to scroll as normal and also acts as a custom play button that would distinguish between a scroll and a tap, or perhaps require a double tap to play the video. There is good step by step info on the general principal of how to do that here (https://css-tricks.com/play-button-youtube-and-vimeo-api/). I'd love to hear if others have found a better option to fix this.

As far as i know you cant have scrolling iFrames on iOS devices
since the scrolling is done with a touch/sliding/gesture
it will scroll the whole page...ie: if you try to scroll
the contents in a iFrame it will scroll the whole page...so the iFrame
will move away with it.
So you could look more in the direction where you dont use scrolling frames,
or make shure theres no need to scroll (content is size of frame it is in),
or use a fancybox-type-of thing where the content is on top instead of in a frame,
or have 2 (jquery) buttons that when pressed do the up/dwn scrolling (instead of a scrollbar),
or have a link which opens the player in a new page,
or the standard way where video opens directly in the iOS player itself (QT/Safari).

Dynamically Resizing Flash Object to Fill Window

I have a Flash/Flex object (Flashlight-VNC), which I would like to dynamically resize to fit the entire window after pressing a button in the Flex app. This would preferably happen without restarting the Flex app (and therefore the VNC session). I would just use the built-in Flash fullscreen mode, however Adobe's somewhat silly security restrictions prevent keyboard input while in fullscreen mode.
How exactly can I do this? I'm already using SWFObject to embed the SWF, if that helps. I am open to any solution utilizing ActionScript, JavaScript, or both, however I am not all too familiar with ActionScript or Flex, and the AS-based solutions I have found involve extending a "Sprite" object to add resize functionality, which Flashlight-VNC does not seem to use.
I see that there is a very similar question already posted on this site, however the accepted answer points to one dead link and another link that does not answer my question (my goal is to resize the object on command, not from when the page loads).
Thanks!

This really isn't related to flash. It's more about HTML DOM manipulation. You want to make sure your Flash SWF is set to use 100%/100% and then when you want to trigger "full screen" mode change the html container to be placed in the top-left-most corner and have a width/height of 100% of screen.
You'll still have the browser's toolbars and tabs and address bar, but if you want keyboard input there aren't many options.
