I've been asked to integrate videos into an existing app which previously only let users upload posts with images.
I don't want to host the videos on my own server for the following reasons:
Server Bandwidth
File Size Limits and Storage Space
Slow-Loading Video or Unexpected Pauses During Playback
Issues with converting to specific formats
Piracy
Based off this article:
https://www.wp101.com/10-reasons-why-you-should-never-host-your-own-videos/
So I tried to research into where I could host the files and then I would simply have to store the URL in my db and use a video player to stream the content.
Vimeo and youtube seemed to be the main options I could find.
I'm wondering how best to implement, would I make use of a youtube API and on successful upload, grab the link and upload to my own server? I'm concerned this may be a long process for the end user.
Another problem is I can't see any swift examples (ZERO obj-c experience) of making the http request but perhaps it is still possible but I'd just have to write the code myself? I'm wondering if anyone has implemented anything like this already as I can't find any examples.
Looking at this question:
How do I upload a video to YouTube from within an iOS application?
None of the links in the comments work and the answer directs to the youtube 2.0 API and I'm concerned that this is now deprecated.
Any advice appreciated!

I've been asked to create an education ebook which contains 200 videos for a total size of 25 Go (!).
Although it is my first ebook creation, I can't imagine to embed so many videos in the epub file, and so, I plan to only use external videos.
Since the making of these videos requested a lot of work (and personnal funds), the teacher want to secure the videos and avoid the videos to be stolen and made publicly visible on other sites.
How can I include external videos in an epub ebook in a safe manner ?
Thanks in advance for any tips !
Short answer: there is no way to 100% "protect" a resource embedded in an EPUB file, if the user has access to the EPUB file itself.
Long answer: unless you are also creating the reading application intended to be used for consuming those EPUB files and thus you can prevent the user from "reaching" the actual EPUB file, there is no 100% secure way of preventing a user from extracting a resource (the video, in your case) from an EPUB file.
Traditionally, to prevent "oversharing" of the EPUB file itself or "unauthorized extraction" of some assets (images, audios, videos) two main techniques are used: DRM or per-purchase watermarking. If you apply a DRM (i.e., the Adobe DRM), there are programs to remove it with just a click. The per-user watermarking route seems difficult for videos, I do not think any watermark provider has a tool to insert hidden user info inside videos embedded in EPUB files.
Another possibility consists in NOT embedding the video inside the EPUB file, and just link to it or to declare it as a "remote resource" (see http://www.idpf.org/epub/301/spec/epub-publications.html#sec-resource-locations ). But again, this does not prevent a malicious user from downloading the video from the URL you need to specify in the EPUB file.
Probably the best solution consists in showing some information (like "(c) Name_of_the_author, 2016") in a corner of the video. Again, very determined pirates might crop that text off, but at least discourage the "casual oversharers".
As with every ePub response, this depends entirely on the distribution channels they require. If they plan to distribute the ePub files directly, and the ePub files are ePub3 / HTML5 compatible, I would suggest this:
host the videos on a site that provides custom domain-level-access to the videos (like Vimeo: https://help.vimeo.com/hc/en-us/articles/224817847-Privacy-settings-overview), then have the video live in an iFrame to your site and require users to authenticate to that iFrame before the videos will play.
This will prevent people from sharing the videos by simply copying and pasting a URL, which will give you client peace of mind. But there will ALWAYS be the possibility of an authenticated user downloading/saving the video and then re-posting it in a public place. But you will always have that possibility regardless of security: because someone can always do a screen record and audio capture for any video they can see.
Best of luck,

I'm building a Rails app that has videos that users will see on the app and they will pay for it. So I need to ensure that no one can download the video. How can I protect, for example, that someone go to the source code the page and find the link and download it?
You can't really do this in standard Rails techniques. If you are serving the file yourself: Dirty Web Video Secret: If You Can See It, You Can Steal It
You can’t guarantee that a video can’t be copied, but you can make it harder by limiting the people with access to the video, by letting those people know that you can track how they view your videos, and by putting some reasonable technological hurdles in the way.
If you are OK using flash, then you can look at Brightcove's solution that uses "DRM" http://support.brightcove.com/en/video-cloud/docs/protecting-your-videos-drm
What do most people do?
They use an authenticated URL that expires (to prevent emailing and sharing), and trust their users won't download and share the videos. They then ignore those that do share (or file DCMA takedown requests).
I test with browser with the link I get from "http://www.youtube.com/get_video_info?&video_id=xx" to see if it is be able to download.
After remove some parameters from original link, some works but some still don't.
I read some post here but most of are pretty old. A lot of change since then.
I wonder if there are somebody working on this recently.
The purpose I need this is because my youtube view program need a better quality video to display.
This is link doesn't work:

What wrong with it? I removed fallback_path and replace sig with signature.
The working link is for webm. This is for h264. Both have the same kind of parameters.
And this is working now.

That's not a supported method of interacting with YouTube. You need to use one of the official YouTube Player mechanisms to display YouTube videos.
Please familiarize yourself with the YouTube API Terms of Service if you have any more questions.
I searched far and wide and came up with nothing.
Ok, that is not completely true, there are in fact tons of solutions on the Internet (even here on stackoverflow) on how to get a download link for youtube video, but not a single one of them is working anymore, since youtube seems keep changing things all the time.
What I want to do, is to write a PHP script which will be able to download video from specified youtube page and then save it on the server in flv or mp4 format.
I can get some video information by downloading this: http://www.youtube.com/get_video_info?&video_id=VIDEO_ID
But thats about it, no matter what I do, I just cannot figure out how find the link pointing to the video download.
I tried to use this link: http://youtube.com/get_video?video_id=VIDEO_ID&t=TOKEN&fmt=18&asv=2 from one more recent solution I found, but either there is something missing in it, or it's completely outdated already too.
So how can I dig out some working link for direct video download from youtube?
There has to be some way to do it, since there are some web pages out there which provide this service.
Thank you for any advices.
I prefer RealPlayer to download videos from youtube and other video sharing sites like metacafe, funnyordie and others. You're able to download in both mp4 or flv format, save them, and view them whenever you'd like.. even if you're not online which is great for travel. http://www.real.com/realdownloader
I have a web application that i have developed in RoR 2.1. In the app, users have the privilege of uploading media files. Currently, only FLV videos can be streamed online since i have given FLV player browser support.I have used the gem Mime Types to identify the file fomats of the media files being uploaded.
I would like to get the feasibility and ways to implement two new requirements
How can i stream all videos being uploaded online? Should I convert these files to flv or
is there any other way of making it possible?
I want the users who upload the videos to set a privilege (count) of how many users can
stream this video on line at a given time. How can i implement this?
1) for streaming you should use a CDN, this should not be the responsibility of your rails app. Lots of options, I have enjoyed working with S3/Cloudfront. Streaming through your app will really hurt the scalability of your platform. Lets the good folks at the CDN deal with this.
2) To throttle the usage -- I would do the following. When a web user wants to watch a video give them a link you your app (vs directly to the CDN) so http://myapp/video/watch. In that method(VideosController#watch) you can count concurrent views, and if under the threshold then perform a secure redirect to the video.
If you must serve files directly from your server use send_file method (doc)
If you are looking for video playback, there a bunch of javascript/html5 video solutions: VideoJS is a pretty good one: http://videojs.com/, It should be able to handle many different types of video formats
