Hi Greg,
I have taken all those changes. I took a fresh checkout on friday.
I have also tried out these config values also. Still it does not fix the problem.
The next step is to find out why the pauses are happening then. The first
thing
to look at is if the audio device is running dry. I would put log statements
in place where the underflow error is caught and the call to
CHXAudioDevice::NumberOfBlocksRemainingToPlay().
I think you will find that the audio device is running out of data.
I take it that you are doing software AAC decoding? What is the bit
rate of the clips that have problems? Do clips that play fine have
the same bit rates?
Below you mention that certain sample rates don't play while
others do. Does that hold for *all* clips? Does every clip encoded
at 22050Hz, for example, not play? If that is the case then you
might want to check and see what sample rate the audio device is
getting opened up at. Look at the calls to CheckFormat in hxaudses.cpp
and also make sure the physical device is getting opened up at the
rate the engine thinks it is. Could be a resampling problem perhaps.
Try those things and see what happens.

Thanks,
Rajesh.

Hi All,
I have been integrating the AAC into Symbian player. I could observe that certain AAC clips does not play completely and has lot of Pauses in between. The frequency of pause is very high that the playout is not smooth.
I tested clips (Local playback) with different rates. And playout was ok for
8KHz, 16KHz, 32 KHz and 48KHz. For other rates ( 11025Hz, 22050Hz, 24000Hz,
44000Hz) , the player introduced a lot of pauses.
Symbian player was built of helix_1_5_0 cayanne branch.
I hope there is some kind of calculation using the different rates which is giving this problem. Could someone help me on this ?
How recent is your code? We checked in some fixes for this onto the 150Cay
branch last week
or the week before. Try that and also perhaps add these values to your prefs
file:
R1_Mobile_4_0.cfg:
AutoBWDetection=0
CheckAudioPct=10
RDTFeatureLevel=2
ServerSideRateControl=0

Thanks,
Rajesh.
