Is there any possibility to create a YouTube playlist that will work in a real time.
All viewers will watch the same content at the same time as the traditional television.
https://viloud.tv offers this feature, but I wonder is there some script or way of embedding to achive the same thing.
You will probably have to start a live stream.

I hope you are doing well!
I am working on an eLearning website and came across the topic of the video loading. Since videos are of various sizes, it would be impossible to make the user wait for the entire download of the video for them to start watching, so it must be taken as a stream where the video keeps loading content as the user watches (similar to YouTube I guess). However, I am failing to find how this works? I've been recommended the use of SCORM and xAPI to help with this but I am only finding help on how to upload SCORM files or how to write xAPI code and not how to set them up in our website.
How can we make our videos download as the User watches? Are SCORM and xAPI actually what we should be looking for?
For context, we will be using React JS for our Frontend and will be saving the videos on a server.
I would greatly appreciate any advice you have and thank you for your time!
We tried using xAPI and SCORM however we aren't understanding how they might help
SCORM and xAPI by themselves are not going to assist you with this in general. To stream video via an eLearning course you will need to use a video player (such as the HTML5 video player or video.js) that understands streaming video protocols and to encode the video files in a format supported by that player. I would suggest reading about HLS for instance, though I didn't read the entire page, this is a good place to start: https://www.dacast.com/blog/hls-streaming-protocol/
A traditional eLearning course, such as you would have with SCORM, is going to provide a reasonable way to wrap the playing of video such that it can be launched for a learner via an LMS and may capture data such as completion. xAPI is probably suggested because it provides a more robust way of enabling the capture of interaction data such as when the learner plays, pauses, or seeks in a video. My preferred approach for doing this is to leverage cmi5, and there is an example of xAPI video profile usage within a cmi5 course in the Project CATAPULT sample content, see https://github.com/adlnet/CATAPULT/tree/main/course_examples. It could be adapted to leverage something like HLS and get streaming capability. Confirm with your LMS of choice ahead of time whether it supports cmi5 as adoption is still lower than for SCORM.
SCORM Cloud (a bit of a misnomer, https://cloud.scorm.com/) provides builtin video handling via the cmi5 mechanism and will soon support video streaming beyond just from YouTube without the need to author a course separately.
I'm trying to put together an open source library that allows iOS devices to play files with unsupported containers, as long as the track formats/codecs are supported. e.g.: a Matroska video (MKV) file with an H264 video track and an AAC audio track. I'm making an app that surely could use that functionality and I bet there are many more out there that would benefit from it. Any help you can give (by commenting here or—even better— collaborating with me) is much appreciated. This is where I'm at so far:
I did a bit of research trying to find out how players like AVPlayerHD or Infuse can play non-standard containers and still have hardware acceleration. It seems like they transcode small chunks of the whole video file and play those in sequence instead.
It's a good solution. But if you want to throw that video to an Apple TV, things don't work as planned since the video is actually a bunch of smaller chunks being played as a playlist. This site has way more info, but at its core streaming to Apple TV is essentially a progressive download of the MP4/MPV file being played.
I'm thinking a sort of streaming proxy is the way to go. For the playing side of things, I've been investigating AVSampleBufferDisplayLayer (more info here) as a way of playing the video track. I haven't gotten to audio yet. Things get interesting when you think about the AirPlay side of things: by having a "container proxy", we can make any file look like it has the right container without the file size implications of transcoding.
It seems like GStreamer might be a good starting point for the proxy. I need to read up on it; I've never used it before. Does this approach sound like a good one for a library that could be used for App Store apps?
Thanks!
Finally got some extra time to go over GStreamer. Especially this article about how it is already updated to use the hardware decoding provided by iOS 8. So no need to develop this; GStreamer seems to be the answer.
Thanks!
The 'chucked' solution is no longer necessary in iOS 8. You should simply set up a video decode session and pass in NALUs.

Is there anyway to shut down a YouTube video that you've embedded on your page? It seems like they play to the end, no matter what. What I'd like is some way to use JavaScript to send a STOP signal to the YouTube player to completely disengage from the video and show whatever was there before the video was started. An END signal from the video player would also be nice, that called my JavaScript when the video finished.
By the way, I notice when I right-click the playing video that one option is "About the HTML5 Player" so apparently YouTube is using the HTML5 player. That might make the task of communicating with the player with JavaScript a bit easier.
Thanks for any ideas.
Yes, there is a way. Use what official documentation says: player.stopVideo(). If you have a problem with it, see Stop a youtube video with jquery? and How can I stop a video with Javascript in Youtube? as they not only contain solutions to common problems but discuss alternative ways of achieving the same goal.
I would like to write a DJ's jukebox as a software which streams videos either from YouTube or from existing MP3s, and, I need to design the following:
playlists
repeat the same track
hopefully do some mixing as well
based on treble, bass and other frequencies of music coming from
different channels
...amongst others
Does YouTube allow this? Can I code this kind of music mixer? How?
YouTube has no official API for this.
You could download videos from YouTube (e.g. with yt-download), and separate the audio (e.g. ffmpeg-i video.flv audio.mp3); and use filters, like those provided by sox.
Also, in many places downloading most music from YouTube is a violation of copyright law. Distributing this application could get you in a lot of trouble, because you're encouraging people to break copyright law. (to my understanding).
After struggling with getting Ytd to work for a couple of days I'm about to dive into Youtube Direct Lite which looks much friendlier to set up.
My first question is about the playlist size limit. Once a playlist is full (200 videos?) what would happen with further video submissions? Would the oldest be dropped or is it just impossible to add any more, effectively breaking the widget for that playlist?
I expect I would need to use multiple playlists and manually make new playlists and widgets if there's a lot of videos, but is there a best practice kinda way to do this for a large number of videoslso?
Also, would it be possible to automate the submission approvals programmatically if there's a lot of videos or is this beyond the scope of ytd-lite.
Thought it's better to ask these questions now before starting the process of setting this up for my site. Ytd-lite looks like a great project.
thanks.
from the Doc:
https://developers.google.com/youtube/2.0/developers_guide_protocol_playlists#Adding_a_playlist
Note: Playlists contain a maximum of 200 videos. As such, you will not be able to add a video to a playlist that already contains that many videos.
I dont'n try to force this situation but I expect an error.
I believe that to automate the submission approvals programmatically you can modify the source code of YouTube Direct Lite, and with a little logic in the server side of your app you can do what you want.
