There are two media files hosted on external servers - audio and video. I need to mux them and play as online stream through Android MediaPlayer class.
The main problem, is that I don't know, if there is any possible solution for continuous download-mux-play process. I've seen examples of MediaMuxer class usage, but only with local files.
Currently, I just start two media players like this :
//Setting up video
MediaPlayer video = new MediaPlayer();
video.setDataSource("videurl");
video.prepare();
//Setting up audio
MediaPlayer audio = new MediaPlayer();
video.setDataSource("audiourl");
video.prepare();
//Starting both players simultaneously
video.start();
audio.start();
But, of course, this gives terrible synchronization between audio and video. So, the question is - is this even possible to mux online streams, and if yes - where do I start research?

I have an Exoplayer example in my android TV application which stream udp url like below
udp://232.196.x.x:xxxx
the streaming working well but the video is playing without any audio or any sound.
i need to select the default audio track using DefaultTrackSelector
I have an app that plays video files with no audio. I'm using the mediaplayer function. I want to have the videos play, but not output anything to audio, as there is no audio tracks. However, Android ducks all other audio output (music, for example) when my app is running. Is there a way to use mediaplayer and completely remove my app from audio streams?
I've reviewed Google's Managing Audio Focus article, and I can't devise a way to do so. I just want to use mediaplayer for the video, and completely forget about audio.
Is there a different function I have to call in mediaPlayer.setAudioStreamType?
you can mute all the audio streams using the below code snippet
AudioManager am = (AudioManager)NextVideoPlayer.this.getSystemService(Context.AUDIO_SERVICE);
am.setStreamMute(AudioManager.STREAM_MUSIC, true);
I am developing an application in which I have to perform three functions play, record and pause an audio file.
Has anyone implemented it before?
Take a look at MediaPlayer or AudioTrack for playback. The difference is that MediaPlayer can play several audio formats directly from file (or in some cases even from remote URL), while AudioTrack plays only from raw LPCM buffer,
For recording take a look at MediaRecorder or AudioRecord. The difference is that MediaRecorder records audio and video to .3gp, while AudioRecord gives you only audio as raw LPCM buffers. The AudioRecord data can be used to create .wav files (though some extra code is required for this).
I have made a Android streaming application that plays media from online URL's. For playing the media, I am using the
standard MediaPlayer class for playing media.
As per the Android documentation, it supports RTSP protocol for audio & video playback
http://developer.android.com/guide/appendix/media-formats.html
But when I am trying to play media from a RTSP URL, it gets connected but I am not able to hear any media
Following is one of those RTSP URL -
rtsp://sfera.live24.gr/sfera4132
Does anybody media have an idea of playing RTSP URL's through the Android MediaPlayer
Thanks
That link you provided has 3 audio tracks, with the first and last tracks appearing to be silent and don't contain any valid audio.
The middle track has audio (as per VLC). I don't know how Android deals with multiple audio tracks. I imagine you may get better results if you use links that only contain 1 audio and 1 video track at most.
I expect for an rtsp stream with multiple audio tracks, android is only going to play the first one as there is no user interface to select a specific audio stream, hence why you aren't hearing any audio.
If this is a stream from your own server, to hear the audio you should adjust the SDP file the valid audio track first. If this is not from your server, I don't know what you're options are.
I am completely new to displaying streaming either audio or video content using media player.
Somehow using post available here, i am able to display RTSP content(.3gp video) in my MediaPlayer implementation.
How to identify streaming content is audio only stream or audio/video stream using MediaPlayer class or streaming link?
I could be wrong here, but I believe there is only a MediaPLayer.OnInfoListner API available in Java to get information about the content stream being played. Not sure of how helpful that API actually is though. You might also want to try stream scrapers(is what I believe they are called) to get stream data and see if there is both audio and video channel to make a determination.
