ExoPlayer and HLS Streaming

ExoPlayer and HLS Streaming - android

I am writing an Android application that plays a large MP3 file over the web. These files are usually about an hour or so and I've been getting some really inconsistent behavior with the stream cutting off in the middle in some cases.
To fix this, I decided to move to ExoPlayer and utilize an HLS implementation. While I am able to play the Apple test files (the beep boop) without issue, I can't seem to get any of my own streams to work.
Whenever I try to access my own stream, the player errors out and I get the following stack trace:
06-05 18:15:22.898 29566-29566/com.application E/EventLogger﹕ internalError [0.66, loadError]
java.io.EOFException
at com.google.android.exoplayer.extractor.DefaultExtractorInput.readFully(DefaultExtractorInput.java:73)
at com.google.android.exoplayer.extractor.ts.TsExtractor.read(TsExtractor.java:102)
at com.google.android.exoplayer.hls.HlsExtractorWrapper.read(HlsExtractorWrapper.java:214)
at com.google.android.exoplayer.hls.TsChunk.load(TsChunk.java:110)
at com.google.android.exoplayer.upstream.Loader$LoadTask.run(Loader.java:242)
What is the correct way to create an HLS Stream from an MP3 for Android? For testing, I have tried a number of ffmpeg exports and am using S3 to serve the files, but I have been unsuccessful.
One of the samples can be found here: https://s3.amazonaws.com/gte619n/test_stream/output_test.m3u8
Thank you for all your help and suggestions.

Your link works fine in the ExoPlayer currently available at GitHub.
How to do it:
1) git clone https://github.com/google/ExoPlayer.git
2) Open the ExoPlayer/demo app in Android Studio
3) Edit ExoPlayer/demo/src/main/java/com/google/android/exoplayer/demo/Samples.java and add
public static final Sample[] HLS = new Sample[] {
new Sample("Stackoverflow",
"https://s3.amazonaws.com/gte619n/test_stream/output_test.m3u8",
PlayerActivity.TYPE_HLS),
and it worked.

m3u8 HLS Streaming not working in Android OS versions 6.0(M) and 5.0(L)

I am using MediaPlayer for Live steaming the Video using HLS medium.
The streaming file has extension .m3u8. The multimedia file is not able to provide streaming in Android OS versions MarshMallow and Lollipop in my case. Above OS version M the same file provides flawless streaming.
Questions that I am looking for the answers are below
Is it Hardware related issue?
Is it only OS related issue?
Why some of the m3u8 urls working fine on MediaPlayer implementation and some of not?
I am here sharing both the files the First one is working and the second one is not working.
1. Here is the First URL that working fine : https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8
One can find the internal details of the file here

Android mediaplayer getDuration() returns 0 for some mp3 files

I have a large collection of mp3 files on my server and i'm using android media player for playing them. The problem is for almost all of them getDuration() method returns 0. I uploaded sample mp3 file and put it somewhere on my server. mediaplayer works perfectly fine with that file!!
I can't understand what's the different. My knowledge about audio files is very limited. Can anyone give me a suggestion what to do?
can I somehow modify mp3 files on my server so mediaplayer can read the metadata?
BTW this problem occurs only on Android. My links on google chrome are fine. and google shows the duration of file right from the beginning of playing when only small percentage of file is downloaded.

We finally fixed this issue by replacing our web server. We replaced tomcat with apache and it fixed the issue. I don't exactly know why

Create a demultiplexer for MPEG 2 TS in android

I have a requirement where I need to extract ID3 tags from a MPEG2 TS(HLS STREAM). MPEG2 has a limited support in android in regards to playing the file. But my concern is to extract the ID3 tags(playing the file is not necessary). Hence I am not concerned with the codecs(encoding and decoding).
I have explored the following options:
libstagefright and OpenMax : A playback engine implemented by Google from Android 2.0.
It has a MediaExtractor is responsible for retrieving track data and the corresponding meta data from the underlying file system or http stream. But according to this post Adding video codec to Android I need to build my own firmware or my own media player.I am hoping I don't have to go down that path. More info on stagefright and openMax can be found here:
An overview of Stagefright player
Android’s Stagefright Media Player Architecture
Custom Wrapper Codec Integration into Android
How to integrate a decoder to multimedia framework
Compiling and using FFMPEG: A complete, cross-platform solution to record, convert and stream audio and video. We can demultiplex ts files with this library as mentioned here:
FFmpeg - Extracting video and audio from transport stream file (.ts).
But I am not sure if I will be able to extract the ID3 tags from the HLS Stream. libavformat might be able to do this but I still need to come up with a mechanism for signaling the read metadata to my application.
Compiling vlc for android: I have compiled vlc for android and made some modifications inside the transport module in demux component for extracting the tags, but it is not able to play all the streams that I am supplying to it.
After looking through these options , I am still at a fix in how to achieve this. I don't want to create a media player as I will not be playing the files nor do I want to build my own firmware. Using ffmpeg seems to be the most viable option, but I want to try this without using any third-party or open source library. My questions are:
Is it even possible to create a demultiplexer from scratch that will work on android?
If possible then ,how to go about it ?
Any options that I have missed?
I am new to this. Any help would be greatly appreciated..Thanks

In android, there is a support to extract ID3 tags. Please refer to ID3 module for further details.
Integration of ID3 into MP3 extractor can be found here.
From a quick check, I have found that ID3 is supported from Froyo onwards.

Stream wmv Videos from a url in my android app

i am creating an app for my website which contains lots of wmv video files.
and i want to be able to play them in my app.
i understand that android does not support wmv files so my question is:
is there any way for me to do this without to change all videos format in my site?
any modificatios to my videos via code (java - eclipse) or libraries, any loop holes?

I've been trying to create a site that has streaming video and I could never get Android devices to work with it. Then I found this...

Streaming .m3u file in Android 3.0

I am looking to develop an application where I have to stream .m3u file, this is for ANDROID 3.0 only.
I want to stream this link
dl.dropbox.com/u/2377944/test/abr_test/index.m3u8
it must work in emulator too
I searched a lot, but nothing seems to be working too good.
Please help.
Thanks in advance.

m3u is a play list format, a text file, and not actually audio/video media itself. That means it references media that you would want to stream. The distinction is important.
The contents of the m3u file is important. (Your link is dead, btw.) Show that to use and we can help more. Each of the media files contained in the m3u must be valid and point to media that is compatible with Android.
What makes the media compatable? Check the Android Supported Media Formats page.
