阅读更多关于 Can I use Firebase Storage for online music streaming?

问题 What I want is to save mp3 files on Firebase Storage and then stream it to an Android device. All the tutorials on Firebase discuss about the image file upload and download. If there are any other cloud that is more easy than Firebase to store and stream audio for android, then please suggest. 回答1: Firebase provide StreamDownloadTask as Mike has suggested, for getting InputStream but unfortunately MediaPlayer doesn't accept a direct stream. Now we have 2 options if we strictly like to

Audio data streaming in HTML5

阅读更多关于 Audio data streaming in HTML5

I am receiving PCM audio data from the server in small chunks and having them stored in an Array. Now I would like to play these audio chunks sequentially without gaps using some HTML5 capability. Two options which I am looking at as 'possible' solutions are: HTML5 Audio tag with Data URI Web audio API While I am investigating these options, please suggest me any other option or views on the two options I am looking at. Though a cross platform solution will be the best but I can settle for Chrome only solution as Scheduling audio is something the Web Audio API was designed for. If you have the

Realtime Audio/Video Streaming FROM iPhone to another device (Browser, or iPhone)

阅读更多关于 Realtime Audio/Video Streaming FROM iPhone to another device (Browser, or iPhone)

I'd like to get real-time video from the iPhone to another device (either desktop browser or another iPhone, e.g. point-to-point). NOTE: It's not one-to-many, just one-to-one at the moment. Audio can be part of stream or via telephone call on iphone. There are four ways I can think of... Capture frames on iPhone, send frames to mediaserver, have mediaserver publish realtime video using host webserver. Capture frames on iPhone, convert to images, send to httpserver, have javascript/AJAX in browser reload images from server as fast as possible. Run httpServer on iPhone, Capture 1 second duration

Using AudioTrack in Android to play a WAV file

阅读更多关于 Using AudioTrack in Android to play a WAV file

I'm working with Android, trying to make my AudioTrack application play a Windows .wav file (Tada.wav). Frankly, it shouldn't be this hard, but I'm hearing a lot of strange stuff. The file is saved on my phone's mini SD card and reading the contents doesn't seem to be a problem, but when I play the file (with parameters I'm only PRETTY SURE are right), I get a few seconds of white noise before the sound seems to resolve itself into something that just may be right. I have successfully recorded and played my own voice back on the phone -- I created a .pcm file according to the directions in

The easiest way to play an audio RTMP stream in Android

阅读更多关于 The easiest way to play an audio RTMP stream in Android

I found some Android RTMP libraries (like this : http://rtmpdump.mplayerhq.hu/ ). The problem is that there is no accurate documentation on how we can use it. In my case, I have a simple RTMP live audio stream (ex: rtmp://myserver/myapp/myliveaudio). What is the easiest way to read it in my Android app? Please, I don't want links: I need some pieces of code or some accurate step-by-step explanation. Thank you very much. It is unfortunately non-trivially difficult to do. Right now your best bet is to look at the code in http://code.google.com/p/android-rtmp-client/ : specifically look at http:/
