I am new to Flutter App and I have to create a WEBRTC based video and audio calling app for both IOS and Android without using TURN Server with FCM for creating a connection between 2 users.
Could anyone please help me out how can we achieve this functionality?
Need something very similar to Peer js.
Any docs or videos explaining it will also help.
There is actually an existing plugin specific on the implementation of webRTC using Flutter. As for the tutorials, try to check the webRTC codelab and good video tutorial about "Realtime Communication with WebRTC in Flutter & Dart".
We are creating an app using Swift on IOS that needs to use custom audio controls: a play button, a stop button, a current time/pos indicator, the duration and perhaps even a seek bar to play 1 audio file that is built into the application. My friend has worked hard on this project but so far was unable to find a solution. Is it possible using mediaplayer or is another api easier, possibly something similar to exoplayer for android apps.
Thanks.
In my opinion I would say that using AVFoundation would probably be easiest since it is built into swift you just have to do import AVFoundation and you would probably want to create an AVAudioPlayer to listen to the music. Also the API is pretty simple. If you need any help getting started I found this article on Mashable that shows how to play audio and how to control it with a custom play and pause button. https://medium.com/yay-its-erica/creating-a-music-player-app-in-swift-3-53809471f663. Also I found on Apple's documentation how to get the current time of the audio playing https://developer.apple.com/documentation/avfoundation/avaudioplayer/1387297-currenttime. I hope I was able to help and if you have anymore questions don't hesitate to ask!
I am creating one application which requires recording voice and then funny voice will play.
Is there any library to use this work function better?
The SpeakHere sample application provided from the SDK site has a working example of how to use the microphone to record the voice.
Now how to play funny voice.
For that there are no built-in iOS APIs that will do independent time-pitch modification.
There is open source code that implements time-pitch stretching in Audacity, but I don't know whether this code has been ported to iOS. Same with SoundTouch.
There is a Time-Pitch Stretch Tutorial on the DSP Dimensions site.
Some more blogs on it

I'm making my own internet radio app with a custom interface. So i'm wondering what is the best tool to implement the audio playback with a custom interface? I tried to use MPMoviePlayerController, but i couldn't find out how to customize it's interface. I also tried AVPlayer, but somehow it didn't play the .m3u files, though it worked perfectly well with .m3u8 playlists from apple test http live stream examples.
Use audiostreamer its also having a good example https://github.com/mattgallagher/AudioStreamer

In my project i have to use youtube api and play only audio of the video. We must not show the youtube player. Is it possible to play only audio without showing video using youtube api?
Extraction may be the incorrect implied word here. From what I understand, is user133611 wants to have an audio only stream from YouTube. Unfortunately, YouTube directly forbids it. Here is a quote from Kuan Yong from the YouTube API team:
Your API Client will not, and You will not encourage or create
functionality for Your users or other third parties to:
"separate, isolate, or modify the audio or video components of any YouTube audiovisual content made available through the YouTube API"
-Kuan Yong, YouTube API Team

I don't think this is really possible only using Youtube API. The Youtube API is not intended to be used for "downloading" videos/audio from them. You should go here, to understand what the Youtube API is really about.
A small abstract:
Unless I am missing something really big, the Youtube API consists of 5 main parts:
Data API
Custom Player
YouTube Direct
Player APIs
Widgets
None of this APIs allow you to for example "download" a video. Also I think (correct me if I'm wrong), that in a youtube video, the audio is actually embedded in the flash video, making the task even less trivial.
To illustrate you, the Data API, allows you to perform and use the youtube video search capabilities, use playlist capabilities and many more of the operations available on the YouTube website.
That have being said, the Youtube API, can be used for example to upload a video from your iPhone to youtube, as this example illustrates.
My Thoughts:
I think that extracting the audio from a youtube video, is actually possible, but involves a whole different process of downloading the video in H264 and then extracting the audio... but it still involves downloading the whole video.
Is the audio only prohibition still valid? Streamus is available as a Chrome Extension. It streams audio only from YT - see website https://streamus.com/
Well, one can simply give the video a width and height of 1px, or better yet do:
.video { text-indent: -9999px; }
And then force the video to play via the API controls. But I wouldn't do it as it is against their TOS and would result in my app being blocked if they find out.
I really confused about your platform. Do you want to do it over iOS platform with writing native code? If yes, you can do it without playing video. But you have to stream both video and music. You can do it with AVAudioPlayer Class, check the reference from
https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioPlayerClassReference/
But yes, you will makes users GSM data overload and it's not fair with letting users about that situation.
Maybe you can force your view over the youtube view? Have you tried that?
If it is against TOS, the op should just drop the idea of implementing his idea.
Just imagine the free music everyone will be streaming out of the promo videos of major videos on youtube!
