* | ac3dsp: x86: Replace inline asm for in-decoder downmixing with standalone asm | Justin Ruggles | 2016-10-01 | 1 | -37/+75 |
| | | | | | | | | | Adds a wrapper function for downmixing which detects channel count changes and updates the selected downmix function accordingly. Simplification and porting to current x86inc infrastructure by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de> | ||||
* | ac3dsp: Add some special-case handling for the C downmix function | Justin Ruggles | 2016-10-01 | 1 | -1/+38 |
| | | | | | | This is about 200% faster for in-decoder downmixing of 5.0 and 5.1 content. Signed-off-by: Diego Biurrun <diego@biurrun.de> | ||||
* | ac3dsp: Reverse matrix in/out order in downmix() | Justin Ruggles | 2016-10-01 | 1 | -4/+4 |
| | | | | | | | Also use (float **) instead of (float (*)[2]). This matches the matrix layout in libavresample so we can reuse assembly code between the two. Signed-off-by: Diego Biurrun <diego@biurrun.de> | ||||
* | Drop pointless assert.h #includes | Diego Biurrun | 2016-05-03 | 1 | -1/+0 |

* | Update dsputil- and SIMD-related comments to match reality more closely | Diego Biurrun | 2014-03-13 | 1 | -1/+1 |

* | dsputil: Move apply_window_int16 to ac3dsp | Diego Biurrun | 2013-12-08 | 1 | -0/+15 |
| | | | | The (optimized) functions are used nowhere else. | ||||
* | ac3dec: make downmix() take array of pointers to channel data | Mans Rullgard | 2012-12-09 | 1 | -1/+1 |

* | x86: call most of the x86 dsp init functions under if (ARCH_X86) | Janne Grunau | 2012-10-08 | 1 | -1/+1 |
| | | | | Rename the called dsp init functions to *_init_x86. | ||||
* | ac3: move ac3_downmix() from dsputil to ac3dsp | Mans Rullgard | 2012-09-12 | 1 | -0/+26 |

* | ac3dsp: simplify extract_exponents() now that it does not need to do clipping. | Justin Ruggles | 2011-07-01 | 1 | -14/+1 |
| | |||||
* | ac3dsp: fix loop condition in ac3_update_bap_counts_c() | Justin Ruggles | 2011-05-28 | 1 | -1/+1 |
| | |||||
* | ac3enc: modify mantissa bit counting to keep bap counts for all values of bap | Justin Ruggles | 2011-05-28 | 1 | -16/+26 |
| | | | | | | instead of just 0 to 4. This does all the actual bit counting as a final step. | ||||
* | ac3enc: clip large coefficient values and negative exponents rather than using | Justin Ruggles | 2011-05-01 | 1 | -1/+3 |
| | | | | av_assert2(). | ||||
* | ac3enc: move extract_exponents inner loop to ac3dsp | Mans Rullgard | 2011-04-04 | 1 | -0/+23 |
