Libtheora
Hi all,
I am Sahana. I am currently working on Libtheora for windows platform and
very new to it. I am getting a lot of compiling errors. Since Libtheora
depends on libogg and libvorbis i have added these as well to my workspace
in VC++ 6. I have a doubt regarding the x86 and x86_vc folders described in
the libtheora software.Since both these folders have the same set of files
which one do we

CELT Test case failures
Hi ,
We've downloaded the CELTV0.11.1 source code from celt-codec.org . But
having trouble with mathops-test and tandem-test unit test that
exercises internal components of CELT codec, please find attached
document for each test case failure in details.
Also could you please give some inputs on CELT Low complexity code and
full version of the code, point me source code to CELT full versions...

[RFC PATCH v1 0/2] Encode optimize using libNE10
Hello opus-dev,
I've been cooking up this patchset to integrate NE10 library into opus.
Current patchset focuses on encode use case mainly effecting performance of
clt_mdct_forward() and opus_fft() (for float only)
Glad to report the following on Encode use case:
(Measured on my Beaglebone Black Cortex-A8 board)
- Performance improvement for encode use case ~= 12.34% (Based on time -p
