Ross,
I just tried to do the subclass of WAVAudioFileSource and discovered that
the "fPreferredFrameSize" variable in that class is still private. In
checking the release notes for 2012.08.28 I see that the variable was moved
from private to protected in "ByteStreamFileSource." Is this what you
Thank you Ross, much appreciated,

Since my original thread (RTP Packet Size) has been hijacked into a

Hi Ross,
Just an FYI for you, I encoded the WAV files for audio format of "PCM" (no
codec) and the server now plays them out. Also, I tested the new feature
"maxSchedulerGranularity" and it also appears to be working. Many thanks I
much appreciate your patience,

Ross,
I completely understand. As I asked, do you know of a tool I could use to
convert the test files I have been supplied with to plain PCM (format 1).
This is part of a proof on concept so I do not have to play the WAV files as
they are. They can be re-encoded.
Thanks,
Sid.

Ross,
I have built to new code and run into an issue with my test WAV file no
longer playing. Your new WAV parser is rejecting the WAV file because of the
audio format entry which is 0x0012 which is said to be "Videologic

Aha! Thanks Ross that is clear.
My application does not require any external stimuli to cause actions within
the server. It has no UI. If external stimuli were needed I would hope to be
able to subclass "BasicUsageEnvironment" to achieve this without the need
for periodic running of the task sc
No you are wrong! That is not what I meant by events. As an embedded
programmer for more than 40 years I use the term events to mean any
stimulus, internal or external to the current process that signals a
requirement for the attention of that process.

When I comment out the line you suggested the CPU utilization by the process

Thanks Ross.
I used the word "sleeping" to mean that the process gives up any remaining

Sorry it took so long to get back to this. I reworked the front end of the

I can confirm the same issues when compiling for Windows Compact 7.

I am not going to debate whether I should be using Windows Compact 7 or not,
