I am using 2 different assets:
An Audio Recorder: it records audio when started and then it plays it later (Speech Auto Detector).
A Screen Recorder (Android Native Screen Recorder).
When Screen Recorder starts, I want the recorded audio to play along with it. I want to screen record it with the audio but when the screen recorder starts, audio stops because both of the assets are using the same mic to capture the audio. Also, both of the assets work fine separately. Is there any solution?
Thank you.
Someone also had the same problem but with different assets so the solution was little different, also I couldn't understand that solution because I am not that experienced with this topic. So, it will be really helpful if you will simplify your answer.

I'm building an App that plays a mp3 file (hosted on http://<somewhere>/<audio>.mp3) while the user is watching some changing labels (think about a lyrics app, which write the lyrics synchronised with the song).
In the bottom side of the screen I'd like to show the audio controls (play/pause, ff, rew), and a bar for indicating the downloaded part of the file and the playing point.
How is the easiest way to do it? I've already tried with AVAudioPlayer, AVplayer and MPMoviePlayerController, but none of them solved my problem.
You can use MPVolumeView Class.Read the documentation here http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPVolumeView_Class/Reference/Reference.html
Is there a library or built in graphical player to represent a playing audio file in iOS.
I dont want a full screen player, but a small inline player that can be embedded into a UIView.
Does this exist in iOS?
Apple has a good example of this, avTouch. I have successfully adapted parts of their code to display audio levels in the past.

I'm using mpmovieplayer to play video on ios 4, and I want to keep the audio playing when my app enter background, but it doesn't work. I thing it's because video player use GPU to render video on screen and this is not allowed by apple when app enter background.
So, is there any way to do that? There are some apps have this feature, and they seems just use the mpmovieplayer, is it work by detach the video layer of mpmovieplayer?
Thanks for your answer!
You'll need to have separate audio file and video file for this. Play both when you need to play video and just the audio when app gets into background.
I would like to programmatically produce a video using the microphone on the iPad (for sound) and the screen display (for visual)? Is this possible? How should I proceed?
Possible, but not easy. A rough outline:
Start capturing the audio: How do I record audio on iPhone with AVAudioRecorder?
Capture individual images of the screen as fast as you can: How to capture current view screenshot and reuse in code? (iPhone SDK)
Later, combine the two into a video. I have no clue how to do this part.
Does anyone know of a good tutorial on the distinction between the MPMoviePlayer vs AVAudioPlayer vs MPMusicPlayer?
I want to play audio from an mp3 file available at an external URL.
Ideally it is played in an iPod-like audio view. I toyed with MPMoviePlayer but it appears to be more suitable for video, as when audio starts a "movie playing" message displays, the controls disappear and a white quicktime splash page displays.
I would like the standard ipod audio controls to display all the time, and to customize the image behind them.
