Hi,

I'm getting the following debug log when playing some WAV files from different URLs in a loop. I read the WAV files first using ByteArrayOutputStream and then call the javax.microedition.media.Player on each stream, any help would be appreciated! Note that the files are actually being played fine, albeit with large delay in between:

Could we see the code used to create the player in this loop?

Hi Andrew,

Sure you can, here it is,

Thanks!

What BlackBerry Smartphone model and BlackBerry handheld software version are you testing on?  You can find this under Options, About on the BlackBerry Smartphone.  What line of code is triggering the IOException?

Hi,

I am also stuck with the same issue.. I tested my application on both 9000 device simulator with 4.6 os and 9630 device simulator with 4.7.1 os.

I get the same trace of statements in the console during execution.

Please help me out..

Thanks, raju.

I would write the file to the SDCard and see if it would be opened with the media player that came with the device. I have the same code (almost) working. Except that I create input stream to the player instead of from a http connection.

Hi Aviator, Nice to see ur reply...

Can't we stream the file instead of saving the file onto the SD Card.

The BufferedPlayblackdemo sample has not worked either on the simulators 9000 and 9630.
