[opus] Regarding opus audio codec's build & run

[Deepthi Raychoti]

Hi,

I have downloaded the latest stable version *1.0.2 opus audio codec* from
the following link:
http://www.opus-codec.org/downloads/

*Details of OS & CPU:*
OS    : Microsoft Windows XP
CPU  :  intel core 2 Duo cpu

I am using Microsoft visual C++ 2010 Express to build the codec
(opus.vcxproj available in the package downloaded). I am able to build it &
could generate the application opus_demo.exe.

With this executable, I tried to encode 'input_48k.wav" file with the below
command & "input_48k.opus" file got generated.Please check the attached
folder which contains input file,encoded file& decoded file.

*Encoder command line :   opus_demo -e audio 48000 2 94840 -cbr
input_48k.wav input_48k.opus*

Similarly, I tried to decode "input_48k.opus" file with the below command
line. I am getting noisy output here.
*
Decoder command line :   opus_demo -d 48000 2 input_48k.opus
input_48k_decoded.wav
*

*Experiments done:
*
I have downloaded opus tools
opus-tools-0.1.6-win32.zip<https://ftp.mozilla.org/pub/mozilla.org/opus/win32/opus-tools-0.1.6-win32.zip>from
http://www.opus-codec.org/downloads/ link.
With the available executables in this folder (opusenc.exe , opusdec.exe) ,
I am able to get noise free output.

*Case 1:  checking the codec's encoder:*

With the codec's encoded "*input_48k.opus*" file as input,I have run Opus
tool's decoder (which is working fine).
With this, I am getting error message like "This doesn't look like a Opus
file".

*Case 2:*  *checking the codec's decoder:*

With the tools's generated encoded output (opus file which is proper), I
have run codec's decoder to generate the decoded output.
It is not generating any output(0 bytes output).

Can you please help me here.

Regards,
Deepthi
