I download, encrypt and save audio files for offline playing in my app.
The problem is when I play them from offline, I don't want to decrypt entire file before playing because it can take some time. I want to decrypt bunch of start data, let player play, and just add more data during playing.
But I can't find any AVPlayer methods to achieve that.
After some research I found AVAssetResourceLoaderDelegate but I am confused if it will solve my problem and how to achieve it.
Any solutions?

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.

Currently in our iOS Application, we are downloading the video and then playing it, which is indeed taking a lot of time and killing the user experience. Now, we want to shift to directly stream the video or play the video while it is downloading.
I have tried using AVAssetResourceLoaderDelegate. I doesn't play the video at all and displays the mime type as text/html. Maybe because I am loading from a secured URL with headers.
Can someone suggest me a good way where I can stream or Play the video while downloading it. Would be glad if someone suggest a way to Stream the video's directly from the URL.
Here's the needs: People record their video via my App and upload stream to our website, you know, like a live show.
When they are recording, the network goes bad, then record audio instead of video.
And when audience watch, first comes the video, in a certain time comes the audio with a static picture.
How am I supposed to do that? Thanks.
I got this after thinking. So I'll answer by my self.
If you wanna record video and audio separately. Use lower level Library to handle this. Then upload it. And you can get the upload speed, When the speed goes low, you can shut down the video upload process.
I'm building an app in which I need to steam multiple tracks of audio that make up a song. They all need to be synchronized so the song plays back naturally.
I've been able to play back local multitrack audio very well with the solution on this thread: multi track mp3 playback for iOS application, but it looks like AVAudioPlayer isn't able to stream.
I've been looking into working with DOUAudioStreamer because I've read that it's the best solution for streaming audio on iOS without going pretty low-level, but it seems to lack the equivalent of a -playAtTime: method, which is how the tracks were synced up using `AVAudioPlayer.
Does anyone know a workaround for this using DOUAudioStreamer, or have any advice on another way I should approach this? Thanks.
i'm using AFNetworking to download media files. Audio and Video. I use AFDownloadRequestOperation to get a better way to pause and resume large downloads.
i found lots of tutorials for download and for stream media but i need a way to start download and play the unfinished download from disk to get a better experience while playing large files.
does anybody know how to do this?
As Player i use AVPlayer with AVPlayerItem and AVAsset
if there is another way without this 3 Objects it would be great.
