Flash player not working with ranged stream #52

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello,

I downloaded and used the 1.3 version of the player. I'm trying to link it to a 
servlet I developped, which streams music from my database.
I think that the servlet is OK because I can listen to my music using JPlayer 
(native & flash) or directly from the browser.

It's very strange, because if I give an basic www url to an mp3, your library 
works... but when poiting to my servlet, it doesn't. I tried to stream the data 
in one big response (http code 200) or multiple (206 with ranges), it does not 
work (I have the latest Flash player and GWT 2.4). 

Here are the http headers (when using ranges, but same result when using 1 
single large response) :

-> In the player the displayed time is: 00:00 / 00:4294967295 
-> I sometimes have this exception in GWT (in debug mode):

In tomcat, I always have this exception, seems that the player closes the 
connection before I have time to send all the bytes:

Do you have any idea why it does not work ? I'll be glad to help if you want

Hi,

As a workaround, let your URL end in ".mp3" dummy parameter.

HTH.

Thank you very much. If I add that dummy parameter, I get rid of those errors.
The only small problem I still have is that the player only loads the first 
range of the stream (see the response headers in my 1st post) and never 
requests the next ones. Is it a limitation of your flash player, or are there 
some missing headers you may require ?

Thomas

The flash player had not been tested with ranged streams.  I will look into 
that when am little less busy.
