Play singe youtube video in two iframes - javascript

I was wondering whenever it is possible to play 1 single youtube video in two different iframes? I need this for stereo rendering. I can not clone the source iframe into another, because there is a CORS violation regarding the context. Does the youtube player provide any kind of render target functionality? What I need is the following:
Play and download 1 single video
Display the video in two separate iframes positioned randomly on the screen (we are talking about 1 single frame of video being displayed in 2 render targets or textures)
I do not want to start the video twice and have some delays
I do not want to download the video twice to show the same picture 2 times
Does anyone have experience with this?
Kind regards,
Aleš Mohorič

Draggable video scrubbing

I have a MP4 video of a product which shows a 360 of the product (so it looks like it's spinning) - I have it autoplaying on the page and looks great.
I want the user to be able to click and drag on the video to basically rewind or fastforward the video, so they can kind of scroll back and forth and spin the product around as they wish.
We have used the js-cloudimage-360-view library and used images, but because we wanted this as smooth as possible each colour had 360 images and loading times weren't great, we have MP4s which are small in size and load fast but it's just the srubbing I can't get right.
I'd had a look at this https://codepen.io/webandapp/pen/xEjjOJ too but it's supper jumpy, essentially we want if the user drags to the right it fast forwards as they drag, when they stop it should play from that point (and rewinds if dragging to the left) - this should be as smooth as possible.
The video is just a HTML video element like so:
<video id="three-sixty-video" preload="auto" controls loop playsinline autoplay muted>
<source src="/video/video-1.mp4" type="video/mp4;">
</video>
Scrubbing on a streamed video is limited by the speed at which the video can be downloaded, decoded and displayed.
For a large video on most devices and connections it is not practical/possible to do all this as quickly as a user can scroll along the video timeline.
This is why video containers (mp4 etc) often include a track of thumbnail images which are displayed when the user scrubs along the line.
In other words, it is not actually the video you see in the small image in the timeline, but the appropriate thumbnail for that time in the video.
When the user stop scrubbing, the player then requests that section of the video, decodes and displays it. This is (generally) not immediate.
If your video is small enough and is downloaded completely then you may find you can scrub as quickly as you want, but even then it may be device/client dependent - a quick local test with a number of videos seem to suggest it should scrub ok when available locally:
Using a relatively small 30MB, 50 second local mp4 video, available locally on he computer hard drive (a MAC), scrubbing is relatively smooth using the Quicktime client player.
The same video on the same device being viewed by the Safari browser rather than directly by the QuickTime client appears to be similar, although it is hard to be sure. The playback may well use very similar paths under the skin.
Using a much larger 2G, 4K, 2 minute 30 second video, also locally on the hard drive, scrubbing is again relatively smooth both in Safari and QuickTime.
As a side note, if you do decide the solution is to have the video fully downloaded before you play, that is also an interesting challenge. Most effort is usually focused on the opposite, allowing a video to start playing before it fully downloads. You may find that, providing the video is not too big, having the header info at the end (the MooV atom for mp4) will force the browser to download it fully. This is the opposite of the mp4 faststart you will see discussed some places. I'm not sure how reliable this will be as I think some browser may be clever enough to 'search' in the video by making different requests for bytes at the start and end to find the metadata.

HTML5 audio player for website and mobile usage

I have a page that has multiple instances of HTML5 audio players on it (it has multiple .mp3 links, that I want to be playable).
I want to develop my own custom HTML5 audio player, with my own graphics and stuff, and the main thing that I want is to have bigger controls (play button, music scroll, volume knob etc) ONLY for the [mobile/Android] version of the page.
Is that possible ? To have different control sizes (play, pause etc.) for different screen-resolutions ?
with using the #media Rule you can do exactly what you want
CSS3 #media Rule
and there is another document that helps you found if the page is being viewed by Mobile/Tablet/PC and etc...

Banner overlay a html5 video and something happen when click on play

i'm searching for a long time a solution for my necessities but i can't find anything help me.
Well, i have a html5 player with a video (with exception, if not support, use flash) i wanna insert a banner into this video at a certain time and for a certain duration, full screen and normal size.
what javascript code should i use?
the html should be easy:
div
banner (hidden)
video
/div
what javascript code should i use?
2° Question: i always have this player, i want that when the user click for the first time on play, happen something, like open an full size image, or open a video, ecc.
I not found so much on internet about advertising and coding, and i'm not very good with javascript.
So, i hope some one there can help me, thank you.
Display your ad image on page load and ask user to click to play video.
Load your video with a proper player plugin
Start playing video
Continuously check video duration using player API
At a specific duration like (15th second) display and overlay div on top of your video
Done.
Also if you're not that good with javascript probably it's better to start with something less complicated.

HTML5 Play next video without delay

So i'm trying to stream video in segments without using the MediaSource extension. (Because not all browsers support MSE). Now i'm trying to do this by loading two video elements and play the next one at the right moment. But this has a very tiny delay between switching. I tried to keep checking the currenTime of the video and after a tiny fraction play the next video element. But this doesn't really work that well (audio overlaps, or delay)
Mind you that the video are preloaded and loaded from Blob storage. So the loading shouldn't delay the playback.
How can i make this (Or another solution without flash) play smoothly without using MediaSource extensions?
Your best bet is to use two video elements positioned one on top of the other. The first one should be playing the current part (or chunk) of the video. The second video element should be loaded with the blob that contains the next chunk and be paused. It should also be hidden (you can set display:'none' or z-index:-99999). And then when the first video element ends (the end event is dispatched), call the play() method of the second video element, show it, and hide the first one. Rinse and repeat.
This is what the LifemirrorPlayer does.
If the chunks of the stream are perfectly encoded and cut then this technique works. Often it doesn't. Common problems are:
Synchronizing the audio stream is the probably the hardest. After twenty or thirty chunks are played, the audio usually loses sync with the video. This is very annoying for the viewer and hard to detect and fix (i don't know of any solution actually).
The video element doesn't end. This is usually caused by an encoder that has put too much (or too little) content into a chunk. It can also be caused by improperly cut chunks, by a buggy encoder or decoder.
Flickering when the two video elements are swapped. This depends on the browser. However most browsers deal very well with this and the swap is quick and smooth.

Multiple videos as backgrounds: HTML5 or YouTube?

I have a one page website that I would like to have multiple videos on. I want the videos to be full-width of the browser. I have 6 videos in total. I messed around with plugins that allow me to set an HTML5 video as a div background, but when I add multiple HTML5 videos to the page, the video quality is poor, and jumpy. I'd like to be able to autoplay the videos, and keep the audio functional. In regards to loading speed, playback quality, and overall best user experience, does anyone have any suggestions in order to accomplish this? Should I continue with the HTML5 video as a div background approach or try YouTube videos?
Autoplaying multiple videos at the same time on any website especially if they are full width of the browser will make most videos jumpy. If you have them play one at a time you will probably not have that issue.
