I need to read audio and video out of a .asf file that is streamed to my iOS7 application.
I've compiled ffmpeg but I'm notre really sure this is the way to go. If this is the good tool, I do not know where to go from here.
Any pointer ?

I'm able to record slow motion videos at 120fps using AVFoundation. These videos play as expected on iphone and mac quicktime player. But other players like videojs and my own player[AVPlayer] are not able to play it in slow motion. But if I create a slow motion video using iphone native camera app, then these same players are able to play it as expected.
I compared the two videos using mediainfo and two differences came up -
1. Format Profile: High#L5.1 vs High#L4.1 . I used ffpmeg to make my video's profile to High#L5.1 but it didn't make any difference.
Format GOP : M=1, N=120 vs M=1, N=30. Again I used ffmpeg to set N=120 on my video but it didn't make any difference.
I also read online that exporting using PHAsset may help but my video files are created inside my Documents directory and will never go to Photo Album/Camera roll. I can probably try exporting to camera roll using PHAsset and then move it to my Documents directory as a hack (if it works at all). But I really need to know the underlying reason.
Any ideas what is causing this issue ?
Thanks
I want to play a .ogg audio file in iOS. This is the link of URL :-
http://strm.pistache.org:8443/pistache-tel.ogg
I have found some code from Github but that are not doing online streaming.
Can anyone knows the solution for playing .oog file from URL?
There is not any Direct API of IOS to achieve this, but you can use some Library created to Play .OGG files or you can yourself made one of that using ibvorbis 1.3.3

I want to play .mpd files in iPhone app and for that I tried VLC player but it's not working as per expectation and taking too much time to play the video. Is there any other option which i can use to play .mpd files like exoplayer in Android.
I have already implemented VLC media player for this purpose but now I'm looking for another option. Please help if any body have any idea about that.
Google has released a player that can be used with or without their widevine DRM.

So i am currently starting to develop a iOS app that will need to play audio files from iTunes library and modify audio stream with custom DSP effect that needs to modify RAW data.... I am still trying to decide if i am going to go with swift or objective-c...
I know how to access iTunes library using MediaPlayer framework, but i need a simple way to modify RAW audio data while playing and then play the modified stream back.... So the question is how can i modify the stream and then play it back, and if i use other framework than MediaPlayer framework to play songs with my DSP will my app pass the apple review?
This is exactly what AudioUnits are for. You can start here: https://developer.apple.com/documentation/audiounit
I am developing an Audio Application.
I have a set of .caf files of Apple logic Pro.
I would want to extract in information like tempo and if possible other audio data.
I am very less experienced in Audio applications but got some knowledge in audio though.
Any sample code would really be appreciated.
Somebody please save me!!
Thank you
