* Replace call of celt_inner_prod_c() (step 1)Linfeng Zhang2017-06-061-1/+1
| | | | | | | | | | | | Should call celt_inner_prod(). This change is bit exact as original, except for x86 floating-point. In x86 floating-point, it calls celt_inner_prod_sse() which may have different output with the change of floating-point operations' orders.

* Fixes a surround bug on loud signalJean-Marc Valin2017-05-231-1/+1
| | | | | The constant was copied from the analysis code which uses +/-1 as float scaling, but surround_analysis() uses +/-32767.

* Remove redundant codeMark Harris2016-11-051-20/+2
| | | | | | frame_size_select() ensures that frame_size is a valid size or -1, !st->variable_duration is always false, and delay_compensation is no longer needed to choose the frame size.

* Consider per-channel energy bits in surround_rate_allocation()Jean-Marc Valin2016-09-191-31/+40
| | | | | This should also avoid cases where stereo streams receive fewer bits than mono streams.

* Prevents an overflow in multi-stream encoder rate computationJean-Marc Valin2016-09-061-3/+5
| | | | Also avoids stupidly high/low rates
* Allow disabling phase inversion for multistreamMark Harris2016-09-031-0/+2
| | | | Also clarify in doc that conformance issue relates to decoder only.
* Correct multistream variable frame size strideMark Harris2016-08-271-3/+1
| | | | | | | | The multistream encoder input has st->layout.nb_channels channels. The number of channels actually encoded is st->layout.nb_streams + st->layout.nb_coupled_streams, which may be fewer, so ideally it would only analyze those when computing the optimal frame size, but there is no code to do that currently.

* Making calls to opus_packet_pad() on a bad packet return OPUS_INVALID_PACKETJean-Marc Valin2016-07-041-1/+6
| | | | | | | We were previously returning OPUS_BAD_ARG because the failure was only detected in opus_repacketizer_out_range_impl() rather than in opus_repacketizer_cat(). Checking the return value from opus_repacketizer_cat() also addresses the last outstanding Coverity defect.

* armv7(float): Optimize encode usecase using NE10 libraryViswanath Puttagunta2015-10-071-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Optimize opus encode (float only) usecase using ARM NE10 library. Mainly effects opus_fft and ctl_mdct_forward and related functions. This optimization can be used for ARM CPUs that have NEON VFP unit. This patch only enables optimizations for ARMv7. Official ARM NE10 library page available at http://projectne10.github.io/Ne10/ To enable this optimization, use --enable-intrinsics --with-NE10=<install_prefix> or --enable-intrinsics --with-NE10-libraries=<NE10_lib_dir> --with-NE10-includes=<NE10_includes_dir> Compile time checks made during configure process to make sure optimization option available only when compiler supports NEON instrinsics. Runtime checks made to make sure optimized functions only called on appropriate hardware. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
* Extra safety against NaNs in surround_analysis()Mark Harris2015-10-071-1/+1

* multistream: improve arg checkMark Harris2014-11-271-3/+11
| | | | | | | | | Avoid undefined behavior (signed arithmetic overflow) or implementation-defined behavior (malloc(0)) on out-of-range arguments, e.g. opus_multistream_encoder_create(48000, 2, 2147483647, 1, ...) or opus_multistream_surround_encoder_create(48000, 3, 0, ...).

* Takes into account a corner case with the multistream encoderJean-Marc Valin2014-09-041-1/+1
| | | | | | Considers the case where one stream would eat up all the remaining bytes, including a 2-byte size that would then not leave enough for the even a PLC packet in the next streams.
* Lowered the smallest packet that the multi-stream encoder can encodeJean-Marc Valin2014-09-041-15/+7
| | | | | Limit now at 2*streams-1 and anything below that returns OPUS_BUFFER_TOO_SMALL rather than OPUS_BAD_ARG
* multi-stream fix when setting bitrate to AUTO, MAX, or small valuesJean-Marc Valin2014-06-211-4/+30
| | | | | | OPUS_AUTO should now work fine, while using OPUS_BITRATE_MAX would still be a bad idea for controlling CBR rate for multistream. The encoder should now throw an error early on if max_data_bytes is just too small to do anything.
* Fix surround encodingMark Harris2014-01-261-1/+1
| | | | Broken by 306d7f5a308e30ce10ba1a1dcdbeeb81de3b2872
* Optimizes encoder NaN detection and clipping by only running them when neededJean-Marc Valin2013-12-091-6/+7
| | | | | NaN detection should now be able to catch values that would create NaNs further down.
* Surround low-passing thresholds set to much lower bitratesJean-Marc Valin2013-11-241-3/+3
|
* Adds OPUS_SET_PREDICTION_DISABLED() ctl to force "independent" framesJean-Marc Valin2013-11-151-0/+2
| | | | | | Works by turning off pitch and energy prediction in CELT, while setting first_frame_after_reset in SILK to disable pitch and LSF interpolation and reduce LPC gain.
* Adds packet padding that works for all codes and fixes 40/60 ms CBR.Jean-Marc Valin2013-11-131-8/+3
| | | | Padding is now handled by the repacketizer.
