<DIV><FONT face="Times New Roman">We use ThreadX OS and Green Hill Multi
compiler. Let me summarize my questions below.</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">1) What is the difference among the code based
on windows, symbian and liuxarm platform, except the platform and OS dependent
parts? Is there any memory or code size optimization for embedded system? What
is the memory requirement for each of them?</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">2) In Helix DNA Client, it seems that there is
no Real Audio decode source code, so need I check out the correspoinding
library for ARM platform? What is the suitable setting for check out in CVS? Or
I need to check out a whole code based on an ARM platform?</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">3) What I need is a command line sample code
which is running in ARM platform and can execute local and
streaming Real Audio playback. You have a lot of sub-projects, which
one is the best I can start from? Linuxarm, symbian or anything else? What
is the check out setting for CVS?</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">4) Actually C code is more suitable for our
platform as there are a lot of new and delete operator in C++. Our SDK already
have a memory control unit, but this memory allocation is out of our control.
Were all the Helix DNA client written in C++? In helixcommunity website, it is
said the linuxarm was written in C, is it?</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT><FONT face="Times New Roman">5) For linuxarm, Eric mentioned that I
need to execute the Real Format Porting and Optimization License, it seems
that this license is for the Real Format decoder. Why get the linuxarm
need sign this license? Does linuxarm include the Real decoder source code? How
can I get the linuxarm source code if singed the license?</FONT></FONT></DIV>

Subject: [Helix-client-dev] C++ Source Code for Helix DNA Client<BR>>>
<BR>>> Hi,<BR>>> We want to port Real Audio to ARM9 platform. We
need <BR>>> the decoder and RTSP / RTP / RTCP or other protocols. The
<BR>>> Helix DNA Client was written in C++, but it is quite <BR>>>
inconvenient to port C++ code to our platform. I found that <BR>>> Real
has a SDK called the RealFormat SDK which is written in <BR>>> C. Is it
possible for me to use the RealFormat SDK and port <BR>>> the protocols I
mentioned above to it?<BR>>> Is there any better idea about it?
Thanks!<BR>>> <BR>>> Best Regards,<BR>>> Xiong
Feng<BR>>> <BR>>> <BR>>>
