Hi

I've learnt through the forum that Nokia 6680 with older firmware cant play larger files. So i thought about streaming the file. The Nokia MMAPI tutorial suggests a way to stream file via HTTPConnection. I have tried to use the code on local file system with few changes as follows

public InputStream urlToStream(String url) throws IOException
{
// Open connection to the http url...
FileConnection connection = (FileConnection) Connector.open(url);
DataInputStream dataIn = connection.openDataInputStream();
byte[] buffer = new byte[1024];
int read = -1;
// Read the content from url.
ByteArrayOutputStream byteout = new ByteArrayOutputStream();
while ((read=dataIn.read(buffer))>=0)
{
byteout.write(buffer, 0, read);
}
dataIn.close();
connection.close();
// Fill InputStream to return with content read from the URL.
ByteArrayInputStream byteIn =
new ByteArrayInputStream(byteout.toByteArray());
return byteIn;
}}

Instead of HTTPConnection, i'm using FileConnection. The above method returns the InputStream, which i use to create a player as follows.

Player p = Manager.createPlayer(urlToStream("File:///..."),"audio/mpeg");

When i run the application on actual device, it asks for the read/write permission. The application, then waits for 3 to 4 seconds and exits. Please tell me if thats the right way or give me some other suggestion to play larger files (other than upgrading the firmware;-) ). Thanking in anticipation

hi syson,

not sure what docs you are reffering, but 6680 does not have streaming support,
also you can stream only via rstp or http depending on os version:
from "Java Developer Library" (recent edition):

Streaming

RTSP
The implementation supports Real Time Streaming Protocol (RTSP). RTSP player can be created by using the Manager.createPlayer method with the locator starting "rtsp://".
A RTSP network access point must be set from RealPlayer, or Player.prefetch throws MediaException with the error code -39. RTSP connections always use the default access point set in Real Player. Depending on the product and operator configuration, a default access point may be set automatically.
A 3G network connection is recommended to achieve smooth streaming
The playable content types can be queried dynamically by calling Manager.getSupportedContentTypes( "rtsp" ).
The supported content types for RTSP are listed in section Content types.

S60 3rd Ed. FP 1: HTTP
S60 3rd Ed. FP 1: HTTP streaming player is created using the Manager.createPlayer method with the locator starting "http://".
Contrary to RTSP streaming, a HTTP streaming network connection is not dependent on RealPlayer. Instead the default Internet connection access point is used. If a default access point has not been set, then an access point selection dialog is presented.

A 3G network connection is recommended to achieve smooth streaming

HTTP Streaming is supported only for the content type audio/amr. With other types, the media data is downloaded completely before playing.
InputStream

Streaming from an InputStream is not supported. All the data available in an InputStream is consumed into a buffer before a player is created.

Peter

Hi Peter!

Thanks a million for sharing ur knowledge. As i mentioned in my first post, I'm just trying to develop an application which could play larger files even with small heap size. From ur message it seem impossible though :( Do u think there could be any other way of acheiving that end? Please give ur suggestion. Thanx

hello,

#1
maybe if you are responsible to provide music assets for that phone try to convert mp3 to AAC music file format (its available as compression format e.g. in PC Suite tool) - mime type "audio/aac",
#2
try upgrading firmware version:
http://discussion.forum.nokia.com/fo...light=6680+mp3
your issues coudl be related to firmware on phone,

hth,
regards,
peter
