* Fix 8101b33 to decode ignored redundancyMark Harris2022-06-261-5/+9
| | | | | | | Even if the redundancy is ignored, the final range from the decoder is needed for testing. Reviewed by Timothy B. Terriberry.
* Correct redundancy handling with lost/DTX framesMark Harris2022-06-251-2/+7
| | | | | | | | | | | | | | | | | In https://github.com/xiph/opus/issues/253, the encoder generates a Hybrid frame with redundancy, to switch to CELT-only mode, and then activates DTX immediately afterwards. The decoder ran Hybrid PLC, which isn't right. Use CELT PLC instead if there was already a transition to CELT via redundancy at the end of the previous frame. Also do not use a stale CELT decoder to decode a second redundancy frame when the first redundancy frame for a transition from SILK-only mode was lost. Instead of mixing in old audio from the last time that CELT was used, ignore the second redundancy frame in this case. Alternatively the CELT decoder could be reset before decoding, but it would not be ready until after the 2.5 ms of audio that is needed. Reviewed by Jean-Marc Valin.

* Fixing no-redundancy CELT->SILK and CELT->hybrid transitionsJean-Marc Valin2018-03-271-20/+28
| | | | | We make sure the CELT PLC we do in the transition uses the same bandwidth as the previous (CELT) packet and not the new bandwidth

* Cisco optimization for x86 & fixed pointxiangmingzhu2014-10-031-1/+3
| | | | | | | | | | 1. Only for fixed point on x86 platform (32bit and 64bit, uses SIMD intrinsics up to SSE4.2) 2. Use "configure --enable-fixed-point --enable-intrinsics" to enable optimization, default is disabled. 3. Official test cases are verified and passed. Signed-off-by: Timothy B.

* Preventing unnecessary stack use when using a large decode bufferJean-Marc Valin2014-01-071-0/+18
| | | | | This was causing pseudostack builds to fail because opus_demo uses a 2-second buffer.

* Moves opus_packet_parse_impl() from opus_decoder.c to opus.cJean-Marc Valin2013-10-281-181/+0
| | | | Because it's indirectly used in the encoder (through the repackerizer).
* Add a little missive when compiling without optimization.Gregory Maxwell2013-10-281-2/+6
| | | | | | | The library really depends on all the little fixed point math functions being inlined in order to get acceptable performance. It turns out that it's very easy for someone to compile with optimization disable when twiddling cflags or cooking up their own build system.
* Replace "inline" with OPUS_INLINE.Gregory Maxwell2013-10-281-1/+1
| | | | | | | | | Newer versions of MSVC are unhappy with the strategy of the build environment redefining "inline" (even though they don't support the actual keyword). Instead we define OPUS_INLINE to the right thing in opus_defines.h. This is the same approach we use for restrict.
* Oops, thanks to Mark Harris for spotting this!Jean-Marc Valin2013-10-141-1/+1

* opus_packet_parse_impl() now computes the packet size with paddingJean-Marc Valin2013-10-141-15/+16

* Fix 40/60ms zero-length frame decode failureMark Harris2013-10-111-8/+18
| | | | | | | | Decoding failed with OPUS_BAD_ARG on a packet containing a 40ms or 60ms zero-length frame when it followed a hybrid or MDCT frame. It now invokes the PLC for the duration of the packet as expected. Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
* Do up-front validation of multistream packetsJean-Marc Valin2013-10-111-10/+9
| | | | | Prevents the decoder from being out-of-sync on an invalid packet. Also returns OPUS_INVALID_PACKET on a corrupted FEC packet.

* Add run-time CPU detection and support for ARM architectureAurélien Zanelli2013-06-041-0/+3
| | | | | | | | | | | | Run-time CPU detection (RTCD) is enabled by default if target platform support it. It can be disable at compile time with --disable-rtcd option. Add RTCD support for ARM architecture. Thanks to Timothy B. Terriberry for help and code review Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>

* Fixes FEC issues introduced in 7fcd66cJean-Marc Valin2013-04-231-6/+9
| | | | | | This left FEC disabled on the decoder side for all cases except concatenated packets. Also fixes a FEC bug in opus_demo (wrong output buffer size calculation).
* Applies soft-clipping to the int decoder API.Jean-Marc Valin2013-03-011-7/+16
| | | | | | | | opus_decode() and opus_multistream_decode() now apply soft clipping before converting to 16-bit int. This should produce better a higher quality result than hard clipping like we were doing before. The _float() API isn't affected, but the clipping function is exported so users can manually apply the soft clipping.
* Fixes OPUS_GET_LAST_PACKET_DURATIONJean-Marc Valin2012-12-051-0/+7
