Prevent jwplayer video to download from chrome mobile browser - javascript

I am working on jwplayer video and I need to prevent the video from download.
When i double click on mobile chrome browser while video is playing it gives me the download option.
I have study so many articles and blogs posts about this but still could not find any solution.
I don't want to use HLS stream option. Is there any parameter jwplayer use that recognize the authenticated users and play video only for them? or is there any other way to do it.?

If you are worried about the video being copied by authorised users then ultimately there is no way to stop the user downloading it - the video has to get to the device/browser for it to play and it is not hard to get around any URL obfuscating etc.
The usual approach to avoid copying is to encrypt the video and use some secure way to send the key to decrypt it.
This is essentially what DRM systems do.
The stronger DRM implementations generally also make sure that the end user or application never is able to . This is done by having the encrypted video and the key do their work within a 'secure media path' in the device, that applications and even the OS have no access to.

How can I capture an audio stream playing in my application, and then it use it as a valid input for Web Audio API for visualization?

I am building an app that I want to be able to capture browser audio from say Spotify or YT. And then make it so that I can turn it into a live stream to input into Web Audio API to create visuals while the audio plays. I've came across technologies like Jack and MediaCapture API but wanted to know if anyone has an efficient approach. Any ideas and suggestions are appreciated greatly.
UPDATE:
Was able to get my audio to stream in my application's tab. I am looking for an approach on how to capture the audio to analyze it. I've seen a method where it can be captured through microphone hardware, but I wanted to capture just the audio without any interfering noises.
You can use getDisplayMedia() to get a MediaStream from other tabs, but this is subject to browser support. Chromium-based browsers support this, but others are less compatible at the moment.
Additionally, the UX isn't very good. It depends on the user first choosing that they want to capture another tab, checking a box to share that tab's audio, and then continuing. Also, you need to then stop the video track you get back.
You might consider participating in these discussions to push for better browser support:

How to download/save HTML5 Video on IOS to device

I'm building a web application that creates a slideshow mp4 video. It will be uploaded to S3 and viewed through HTML5 . The goal is to share it on instagram but instagram doesn't allow direct sharing through web. Hence, the alternative is to get the user to download it to their mobile device and upload it manually through the app.
On Android, I'm able to download the video using it's video controls or through <a href='s3-video-link.mp4' download>
However this doesn't work on IOS. How can I download a html5 video onto the mobile device? Can I download directly from s3 somehow? Or is there any possible option to get it to upload to instagram?
The sandboxed nature of iOS means that while Safari can access and download a file unless there is an app registered to handle that filetype that immediately accepts it then it is lost to the user.
If the user has the Instagram app installed, then you could use their custom URL scheme to reference the asset, but the documentation seems more targeted to images than video so YMMV.
There have been some attempts to reverse engineer the APIs that their app uses, and create ways around their current limitations, but nothing that would address your requirement (the various sharing widgets that target Pinterest, Facebook etc don't seem to support Instagram so it's a common problem). Might be worth reaching out to their developer support folks?

Audio recording with HTML5

I'm trying to implement audio recording in a website. Basically the user should be able to press a button and speak something into the microphone. The recorded audio should then be sent to the server for further processing. I realise that you can do this with Flash, but for now I'm trying to avoid that.
I found several resources on the internet about it (i.e. link) but as it seems, this functionality is not widly supported yet. I experienced differences betweet the used browser and between the used operating system. For instance, the Chrome Browser doesn't seem to access any microphone on Linux correctly. So i was wondering if anyone knows a good resource to dive into this. Or maybe someone tried to set up something like this himself, and can help with some suggestions about where the limitations of HTML5 and the JavaScript Web Audio API are right now.
Thanks!
As of Chrome Version 27.0.1453.56 beta Mac, audio recording works with this demo application https://github.com/mattdiamond/Recorderjs
This app returns back a WAV file for the user which can be uploaded to the server.
If you want a truly robust solution that works on most desktop web browsers, you may need to resort to Flash.
This article covers up pretty well the current state of audio video capture possibilites using HTML5:

Also for just audio capture, here's a gitHub project that records audio to mp3 directly from the browser:

How do I block/prevent video downloader addins or programmes?

I have a video site using a HTML5 video player. Users pay money to join the site. But the download manager (in mozilla) or real player download manager can download our videos from the server.
I want to prevent or block these applications. How can I prevent the programs from running?
There is no DRM (Digital Rights Management) in the HTML5 spec, so you cannot do it with HTML5 video.
There are attempts to add DRM to HTML 5 (Encrypted Media Extensions)
With tech companies abandoning the proprietary Flash and Silverlight
media players for HTML5, it was inevitable somebody would try to
inject DRM into the virgin spec.
Microsoft, Google and Netflix are that “somebody”, having submitted a
proposed modification to HTML5 to the World Wide Web Consortium (W3C)
for “encrypted media extensions”.
http://www.theregister.co.uk/2012/02/23/microsoft_google_netflix_html5_drm_infection/
However, such extensions are not available today and will not be for some time, if indeed the proposal is even adopted.
If you need DRM, you will need to use a video technology that supports it.
Even with DRM you simply can't - whatever you've sent to client (keys/content/whatever), client can simply save and replay when he needs decoded stream again. The only solution that would reliably delay decoding, is some hardware solution, but as I understand you'll be going over regular HTTP and browser.
Your problem is legal one and should be solved with legal means.
Overlay their unique user ID onto the video, so if they do capture it, then legal action can be taken as you can prove it's them that downloaded it.
other than that, nothing you can do really...

Audio streaming and voice recording via HTML and Javascript

I'm on a new project that requires to stream audio files (mp3) and record voice messages.. of course my first option was to use flash. But the problem is that the customer wants the website to be iPhone friendly.
Is there any technologie that allows me to play and record voice messages just with javascript/php/xhtml?
And of course, the website should be fully compatible with firefox, safari, internet explorer, etc.
I googled it and everything I found was flash-based.
but if you have any clue about it, please let me know.
No. Not even the new-ish HTML5 has any features to record audio. You'd need to go through Flash or Java - but that would rule out iPhone.
if you want to record sound you should do it with the new HTML5's api's, you can read more about it on
https://labs.ericsson.com/developer-community/blog/beyond-html5-audio-capture-web-browsers
However, this is theory, in reality no browsers support it and there is no way to do it. So in short: you cannot do what you ask.
What you could do is create an iPhone native app for those who want to use iPhone, and a flash website for those who want to access it with a regular browser.
