Fixes a minor CELT->SILK switching glitch in the decoder

By not reinitializing the stereo state during a switch, the old stereo
memory would create a false impulse (i.e. single sample) in the decoded audio.
This change affects the normative part of the decoder. Fortunately,
the modified decoder is still compliant with the specification because
it still easily passes the testvectors. For example, for the float decoder
at 48 kHz, the opus_compare (arbitrary) "quality score" changes from
from 99.9333% to 99.925%.

6 years agoFixes an out-of-bounds read issue with the padding handling code

Fixes an out-of-bounds read issue with the padding handling code

This was reported by Juri Aedla and is limited to reading memory up
to about 60 kB beyond the compressed buffer. This can only be triggered
by a compressed packet more than about 16 MB long, so it's not a problem
for RTP. In theory, it *could* crash an Ogg decoder if the memory just after
the incoming packet is out-of-range.

6 years agoAllow the build files to override OPUS_EXPORT.
Ralph Giles [Thu, 29 Nov 2012 19:01:27 +0000 (11:01 -0800)]
Allow the build files to override OPUS_EXPORT.

OPUS_EXPORT was conditionalized on OPUS_BUILD, so that symbols
are export based on public header declarations when building
opus as a library, but not when those headers are included in
other programmes. This doesn't address the case when the opus
source and its caller are both included in the same monolithic

In that case we want to define OPUS_BUILD, to indicate that we
are compiling the codec source, but not export the symbols. To
support this, only define OPUS_EXPORT if it is not already defined.
This allows build scripts to -DOPUS_EXPORT and override the
platform-specific attribute decortation in opus_defines.h.

Remove obsolete #ifdef OPUS_BUILD.

Likewise there is no reason for it to be conditional.
According to Jean-Marc it's left over from when we had
an alternate CELT_BUILD define.
