How can i convert 3gp file to mp3 without any library android

How can i convert 3gp file to mp3 without any library android - android

I have a recording Android app in which i want to convert the 3gp audio clips to mp3 in order to send them to server. As i have searched the internet, the only way to do that is through some various libraries like
Lame, FFmpeg and others which have some restrictions on my app.
For example the implementation 'com.arthenica:mobile-ffmpeg-full:4.4' which is the ffmpeg has minimumSdk to 24 but mine if for devices the support Android 5.
Is there a snippet of code that can do my job or at lease some kind of useful advice?
Thank you

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

What is the best audio file format to stream on both iPhone and Android

My client do have 10000+ audio songs on a server, he does want to develop an iPhone and Android app to play those songs. He is willing to convert the audio files for any given format.
So what is the best format store those files on the server to consume in iOS and Android ?

OGG is the best I've used so far on both Android and iOS.
Here's the list of libraries for this for other platforms as well.

The best format used by many well known streaming sites like SoundCloud is:
-> 128kbps transcoded mp3
Everything you need to stream is preferred to be in 128kbps transcoded mp3.
Hope that help somebody.

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...

Asx stream on Android

I have a requirement of playing a Asx stream through an Android application
I have read the Android documentation, and they don't seem to support Windows Media streams
Is there any workaround possible? Has anyone did that before? If yes, is there some source code available? Or a library that implements this
Thanks

Are you worried about asx file only or any possible outcome after this?
The asx file can be readable as simple string, read the file using byte array and you can get one or many urls that can be
pls file
m3u file
mp3 url
wma url
We don't have to worry about 1,2 and 3. 1 and 2 can have different parsing logics but at the end they will give 3 [mp3 url] and an mp3 url can be easily handled by MediaPlayer api in android . but 4 is also difficult work to be done.
