How to convert YouTube offline exo file to MP4 or Avi format?is there any way?
I have tried on Google but no solution get.
You can't, exo is compressed and encrypted so only the same youtube App that you used to save it can obtain the video stream content.
The encryption key is specific for the youtube app installation and change from device to device in order to avoid that once you downloaded the content you can distribute it for play on another device.
Ideally if you have a rooted Android device you should find somewhere within the youtube application data the encryption key but then you will not have the required info on how to use that to decrypt the .exo which very unlikely Google will share since with that knowledge its copyright protection system would not be safe.

I am need a solution for protect music file downloaded in an music app.
We have all rights for the audios, so, we need to garante only our app is able to play this audios.
This music app actually is only for streaming. The next update is for implement the functionality for download e play music offline.
I know Spotify , for example, use DRM protection, but it is a little bit controvercious for some people, and I think this is not what we need now.
During my researches, I dont find any concrete solution. So, my questions are which functionalities, libraries or resources can I use to protect the downloaded files.
Maybe I need to encrypt/decrypt the files? But, Swift have a native functionality for this, and have some documentation available?
So, what can I use to protect the audios with Swift, and keep playing the audio only in my own app?
This question gets asked almost daily and the answer is, and will always be, the same - if a user can play your audio on their device, then they can also extract and keep a copy of that audio - no amount of DRM, encryption or any other naive concept anyone dreams up can change this.
You can prevent "script kiddies" from just copying the files off their phone by embedding an encryption key in your app and streaming files through a stream cipher before playing them, but again, it's trivial to reverse engineer and get the key.
You can transcode your .mp3 files to HLS file which will generate one master playlist and several segment files and then you can apply ALS encryption on it using ffmpeg or Apple Media segmenter.

Is there any way to Protect Document Directory in IOS. Any other can not show it's data via any other software? Any encrypted method Or Password Protected for we can protect Data.
My Application is related to Music App. In My app we download songs in Document Directory.
Any user can listen songs via my application. but they can not access that song via any software.
For ex. If we use iFunbox From Mac we can get every data. We don't want to access my data from that kind of software.
Any way to protect my data?
I don't know any way to encrypt an entire directory on iOS devices but you could take a look at RNCryptor to encrypt the songs that your app downloads.
RNCryptor - Github
You can user it to enrypt the songs individually and decrypt the data before you play them in your app.
In
iOS App
for Live streaming
I am getting the response from server
like this, (You can check)

Which is Smooth Streaming file.
How to play this file in my ios app.
Is there any run time converter to convert this file to Apple HLS ?
Any player*(Smooth Streaming)* like
OSMF plugin for iOS
HTML5 player
Silverlight plugin for iOS
Actually :
Actually we have not tried much with Azure Framework. We setted up
the IIS server and got the live streaming.
Played stream by HTML5 video tag in web view.

We can able to play live streaming in our iOS devices.
Still I am happy if I can configure the windows AZure framework to do the same.
You can use the Windows Azure Media Services for converting SmoothStreaming media content into Apple HLS content. Either you use the Management Portal to upload your media assets and then encode it with the preset "Playback on iOS devices and PC/MAC" or you use the REST Api for the Windows Azure Media Services at runtime.
With the REST API you can utilize the Windows Media Packager to encode Smooth Streaming content for HLS. Find a sample configuration for that task here.
I am a bit confused about the YouTube API's term & conditions. If I create an app for users to download only their own videos. Is that against the terms and conditions?
I know downloading other people content is definitely prohibited, but is it the same for your own videos? Since user can go to their video manager and download their own videosm this would be only a short-cut?
Anyone knows can/cannot do this? I was thinking of using this library http://ytdownloadextension.codeplex.com/
Any guidance would be appreciated,

Seems like YouTube already allows you to do that, so I'd say it's legal:
Download your videos
You can’t download other people’s YouTube videos, but ...
You can download MP4 files of videos that you’ve uploaded to YouTube in either 720p or 360p, depending on the video size.
See Download videos that you've uploaded.
I don't think so the Terms of Service of Youtube or the Terms of Service of the API allows you to do so:
Excerpt of Youtube ToS (5. K):
you agree not to access Content or any reason other than your personal, non-commercial use solely as intended through and permitted by the normal functionality of the Service, and solely for Streaming. "Streaming" means a contemporaneous digital transmission of the material by YouTube via the Internet to a user operated Internet enabled device in such a manner that the data is intended for real-time viewing and not intended to be downloaded (either permanently or temporarily), copied, stored, or redistributed by the user.
Excerpt of the API ToS (II. 11):
store copies of YouTube audiovisual content;
Both, state in a very clear way that neither the user nor applications built using the API can "store" content, which is a very direct statement that disallows you from giving such an option in your app. Now, whether Youtube does give its users an interface to download their content or not is an argument out of sequence here as Youtube don't need to follow their own ToS, in other words, it's up to them to give their users such an option, but you can't give it to the users of your app.
I suppose you need a special permission from Youtube to give such an option in your app.
Yes. You can definitely download your own videos from YouTube as it is your own content so you have full rights to it as the creator of the videos.
I'm looking to implement DRM in an iOS video player, but I'm not sure how to implement this. In order to implement video DRM (while still using Apple's hardware accelerated H264 decode), I need a way to feed the decrypted H264 stream into the standard iOS video playback APIs.
According to this question, it was not possible to implement 3rd party DRM in September 2010. There's a thread in the Apple Developer Forums that goes nowhere. However, as of today a number of 3rd party DRM libraries exist: Widevine, Irdeto (PDF), Marlin. They have clearly found some way to pass a custom stream to the media player in Apple approved apps.
I've found two leads. One is a suggestion to create a custom URL protocol, but people seem to have poor success using this with video. The other is to create a local HTTP server thread and provide the content by HTTP live streaming on 127.0.0.1 inside the iDevice. I'd like to be very sure that Apple will approve before going that route.
So - what Apple approved APIs do 3rd party DRM implementations use to get decrypted video data into the video player?
Edit: the latest BBC iPlayer for iOS allows programmes to be downloaded for later viewing. Either they store the content in the clear, or they have cracked this problem.
You can begin decrypting the file into another file and playback that file as you decrypt. You'll need to let it buffer a few seconds worth of video, but it will work.
Additionally you'll need to make sure that the moov atom is BEFORE the mdat atom in the file, otherwise it won't work. (AVFoundation, for example, creates MP4s where the moov atom comes after the mdat atom, and so they would need to be modified to work)
A working solution is local http server. But the patent application was submitted by Authentec.
