mediaplayerstream w/ shoutcast & android 2.1

exjey · May 23, 2013

I 'm coming back because after tons of tests with this equipment:

Android 2.1 emulator (i want this api level because my clients using 2.1 version, by making 2.2+ apps will abandon them so its not an option for me)

B4A - The TOOL !

Audio library 1.32 & MediaPlayerStream object

SHOUTCAST server running locally at "localhost:8000"

-Tried Shoutcast DSP plugin and Winamp, all the encoder settings which exists in the plugin, the only thing that appeared on screen was "media_error_unknown -1"

The reason for my post is that i 've tried VLC to stream to SHOUTCAST server (both programs running locally).

VLC has many more encoding options, all seems to bring the same error message, but right now i've tested RTP: // encoding and reencoding to MPEG-TS MPEG Audio etc subformat, the MediaPlayerStream shows again "media_error_unknown" but with error code -4 instead of -1.

Am i getting close? LOL , i hope someone can help me in this step, maybe we are close to a solution..

Edit: What is the difference of error codes -1 and -4 ? Is there any error tutorial ?

Erel · May 24, 2013

Please check the unfiltered logs and see whether the media player prints any relevant errors.

exjey · May 25, 2013

I am sorry Erel, how do i find "unfiltered logs". Looking so desperate for a solution on this. To get audio via streaming from my company's pc, for android 2.1 platform. I have the control of the streaming PC, meaning i can encode whatever i want, needed for this case. Just cant figure out what settings i have to use.

You are mentioned "Media Player" logs, i am using "MediaPlayerStream" object.

The logs are part of the B4A IDE, look at the right panel, bottom of the screen, click on the tab labeled LOGS, and uncheck the FILTER box.

exjey · May 25, 2013

Thanks NJDude, Erel.

This is part of the log while getting "media_error_unknown -1"

(i have it retry every 5 seconds while i am testing other encodings to the stream, but no change).

I've found this when googling: "Shoutcast streams are nativelly supported only on 2.2. For earlier versions you must create local proxy that changes the response protocol from ICY (shoutcast) to HTTP, which the mediaplayer will support."

This is too SAD. OK, not a suicide thing yet, but lets say to forget Shoutcast, why not. I have the control, i have VLC. I want only this to use a streaming server. It supports everything. I am creating new VLC profile for audio streaming: HTTP , MPEG-TS container , MPEG Audio , listening to port 8080 , path "stream". So on the same computer which runs B4A and runs the project, i have VLC that streams the audio and listens to address "http://localhost:8080/stream" or "http://192.168.1.100:8080/stream". Nothing, i cant get it to work. MediaPlayerStream always showing "media_error_unknown" . Anybody did it.... i mean with Android 2.1 api level. I dont want Android 2.2+ stuff.

Added: I am changing the encodings in VLC, i am getting the same error but with different negative number (-1, -4, -10 etc\)

exjey · May 25, 2013

I was doing something wrong or its the new updated version of VLC i've just downloaded. Just selected :

1) Network streaming
2) HTTP method
3) Audio-MP3 profile
4) RAW container
5) MP3 encoding, 32k 44100

And thats it. It works. MediaPlayerStream and Android 2.1 emulator with so clear sound!

exjey · May 25, 2013

I have 2 android 2.1 devices (1 phone, 1 tablet) , 1 android 2.2 minibook , 1 android 4.0.1 tablet.

Both 2.1 devices are starting the stream fair quick, almost in 5 secs max. The 2.2 minibook delays about 20 secs to start the stream and the 4.0 android takes about a minute to play it.

Is there an explanation for this? The stream quality is very poor, only 24kbps at 44100 Mhz.

Edit: The 2.1 devices have 600mhz processor, the 4.0 have 1.3Ghz processor. So someone could expect the opposite behavior...

Erel · May 28, 2013

Is there an explanation for this?

Not sure. The stream is processed by the native Media Player service.

hi,

about playing webradio using shoutcast, is it sufficient to use mediaplayerstream and audio lib?
i use b4a 3.2, audio lib 1.5.5.

my code is simply like this:

B4X:

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
   
    Dim Media As MediaPlayerStream
    Dim Audio As AudioStreamer
   
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
   
    Media.Initialize("Media")
    Audio.Initialize("Audio", 44100, False, 16, Audio.VOLUME_MUSIC)
   
    Media.Load("http://localhost:7777/")
    Media.Play
End Sub

the audio is audio/mpeg and the stream is up at 48 kbps.

i don't mind if it's even has to force users to use sdk level 14 or above because android 4.0 (ICS) is common device here.

i got error like this from the log (unfilter):

B4X:

** Activity (main) Create, isFirst = false **
setDataSource_l(URL suppressed)
start called in state 4
error (-38, 0)
** Activity (main) Resume **
out_write() limiting sleep time 32199 to 23219


Error (-38,0)

ERROR_END_OF_STREAM

error (1, -2147483648)
Error (1,-2147483648)

Ratna Fang · Feb 15, 2014

sorry... just found a solution NJDude here

so i change my code like this:

B4X:

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim Media As MediaPlayerStream
    Dim Audio As AudioStreamer
   
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    Media.Initialize("Media")
    Audio.Initialize("Audio", 44100, False, 16, Audio.VOLUME_MUSIC)
   
    Media.Load("http://localhost:7777/")
   
End Sub

Sub Media_StreamReady
    Media.Play
End Sub

thanks for providing well documentation/wiki for us

now it's getting easier for me

Hello, sorry in advance for my english. I used the method of Ratna Fang and it works very well but after about 5 minutes the flow this cup. Do you have an idea of the problem? Thank you in advance for your help.

Here is the unfiltered log if it can help.
