* Renaming compute_allocation to clt_compute_allocation() to avoid symbol clashesJean-Marc Valin2018-10-164-4/+4
| | | | As suggested in https://github.com/xiph/opus/pull/83
* Prevent the SILK counter from overflowing after 2 years and 9 monthsJean-Marc Valin2018-09-261-3/+2
| | | | | | | or "just" 1 year and 4 months for 10-ms frames. The overflow can eventually cause a divide-by-zero when counter == -16 Thanks to Dmitry Malinin for reporting the bug.

* Fixes packet parsing for 16-bit CPUsv1.3-rc2Jean-Marc Valin2018-09-141-1/+1
| | | | | | | Without that change, a very long (> 682 ms) illegal packet could trigger a wrap-around in the test and be accepted as valid. Only 16-bit architectures (e.g. TI C5x) were affected.

* Update ISO Base Media Format draft to version 0.8.1.Ralph Giles2018-09-121-100/+108
| | | | | - Switch to 'Opus' file type identification. - Revise channel mapping to better support ambisonics.

* Work around VS2015 internal compiler errorstagingMark Harris2018-07-281-3/+3
| | | | | | | | | | | The error was: c:\projects\opus\celt\celt_encoder.c(1019): fatal error C1001: An internal error has occurred in the compiler. [C:\projects\opus\win32\VS2015\opus.vcxproj] (compiler file 'f:\dd\vctools\compiler\utc\src\p2\main.c', line 255) To work around this problem, try simplifying or changing the program near the locations listed above. Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Internal Compiler Error in C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\x86_amd64\CL.exe. You will be prompted to send an error report to Microsoft later.

* Avoiding arithmetic on NULL pointerv1.3-rcJean-Marc Valin2018-05-291-2/+0
| | | | | Causes a warning with -Wnull-pointer-arithmetic and the code wasn't doing anything anyway (the ctl call ignores NULLs)

* Fixes a SILK bandwidth switching regressionJean-Marc Valin2018-05-244-7/+27
| | | | | | | The bug was triggered because f982b84d started using prefill for SILK bandwidth changes, which reinitialized the encoder state and prevented the variable lowpass from working properly. To fix the problem, we preserve the sampling rate and variable low-pass when prefilling.
* Improving rate control for low bitrateJean-Marc Valin2018-05-174-53/+70
| | | | | | Using a finer table for the rate to SNR curves in silk_control_SNR(). It's now possible to have an SNR that reaches 0, so we can lower bitrate down to ~5 kbps for narrowband and 5.5 kbps for wideband.
* Oops, fix NaN testJean-Marc Valin2018-05-171-1/+1
|
* Aborting on NaN in CELTJean-Marc Valin2018-05-152-0/+11
| | | | | | NaNs should be filtered at the Opus layer, so if there are any in the CELT encoder, then it's likely something went horribly wrong (e.g. corrupted state). In that case, better abort than have something bad happen.
