Hi All,
I have downloaded the Vorbis Codec source code for Windows. How do I
compile, build and run it? Do I need VisualC compiler for that? Also, please
tell me how do I test it?
Is there a easier way of accomplishing the above in Linux?
Thanks,
Niranjan

If not we may need to add some extra instructions for WIndows builds, but please first explain what you have tried.> ???? Is there a easier way of accomplishing the above in Linux?The way described in the README file is fairly standard; whether it is easier or not depends on what you are used to. Does the text in that file help you with compiling, building, running and testing the vorbis codec? Conrad.

Hi Conrad,
With the help of my friend, I opened and built the vorbisfile project in
VisualStudio successfully. We had to change some directory paths. It would
have been better, if clear instructions were given how to use and build the
project in Visual Studio. Also, we did not know how to run the code by
giving the ogg file as input. After some trail and error, we were
successful. Once again, clear instructions on the same would have helped.
Please suggest me where I can get information on what each source file
does with respect to the Vorbis codec. I did not find any detailed
description of the Vorbis codec.
Thanks,
Niranjan

After some trail and error, we were successful. Once again, clear instructions on the same would have helped. As you have now successfully compiled Vorbis in Visual Studio and got the code to run, why don't you write it all up and let others know what the pitfalls are? You are in the best position to give some clear instructions as you have done it. The other gurus may have never used evil Visual Studio and won't want to get their hands dirty. This is what open source stuff is all about.
Thanks for your suggestion. Is there any literature/article on the working principle of Ogg Vorbis Audio Codec? This would help me prepare a presentation.

Hi All,
I see the source codes mdct.c; lpc.c; smallft.c use floats. How do I
modify them to run on a fixed point Processor, with no float functionality?
Is there an integer implementation of Ogg Vorbis Codec?
Thanks,
Niranjan
