* Add new audio filter for encoding multi-channel audio into ac3 at runtime.Gravatar ulion2007-12-13
| | | | | | | | And if set first parameter of this filter to 1, it will do ac3 passthrough like hwac3 did. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@25385 b3059339-0415-0410-9bf9-f77b7e298cf2
* Fix all current known multi-channel wrong order problems by addingGravatar ulion2007-12-10
| | | | | | | | | | | common functions for channel reordering. This fixes these modules by adding channel reordering code for 5.0/5.1 audio: ao: pcm ad: dmo, faad, ffmpeg(ac3, dca, libfaad, liba52), pcm ae: faac, lavc(ac3, libfaac), pcm git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@25343 b3059339-0415-0410-9bf9-f77b7e298cf2

* Change to a 64 bit accumulation variable instead of shifting.Gravatar reimar2007-11-18
| | | | | | | | Changing the way the loop is done is necessary to reduce register pressure. About 20% speedup even on 32 bit x86. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@25103 b3059339-0415-0410-9bf9-f77b7e298cf2

| | | | | | | | | | not any faster. Just removing the += s->samples_overlap - s->num_channels; still provides a ca. 20% speedup on x86 (AThlon X2 64) with gcc 3.4 (compiler stupidity?) git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@25102 b3059339-0415-0410-9bf9-f77b7e298cf2

* A/V sync: take audio filter buffers into accountGravatar uau2007-11-01
| | | | | | | | | | | | | | | | | | Substract the delay caused by filter buffering when calculating currently playing audio position. This matters for af_scaletempo which buffers significant and varying amounts of data. For other current filters the effect is normally insignificant. Instead of the old time-based filter delay field (which was ignored) this version stores the per-filter delay in units of bytes input read without corresponding output. This allows the current scaletempo behavior where other filters before and after it can see the same nominal samplerate even though the real duration of the data varies; in this case the other filters can not know the delay they're causing in terms of real time. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24928 b3059339-0415-0410-9bf9-f77b7e298cf2
* af_scaletempo: code cleanupGravatar uau2007-11-01
| | | | | | | | | Make internal functions static and remove leading '_' from some function names. Cast pointers to compatible 8-bit pointer types instead of ints when calculating their difference. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24927 b3059339-0415-0410-9bf9-f77b7e298cf2
* af_scaletempo: Fix crash in option parsingGravatar uau2007-11-01
| | | | | | | | | | The value of the "speed" suboption was not initialized before calling subopt_parse(). If the command line had suboptions but "speed" was not one of them then the code accessed an uninitialized pointer and possibly crashed. Fixed by initializing the option value. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24926 b3059339-0415-0410-9bf9-f77b7e298cf2
* af_scaletempo: Fix audio copy positionGravatar uau2007-11-01
| | | | | | | | | Because of a missing *num_channels factor the filter copied audio from an incorrect position. This mixed up the channel order and hurt audio quality even if the channels had identical content. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24925 b3059339-0415-0410-9bf9-f77b7e298cf2
* Add audio filter scaletempoGravatar uau2007-11-01

* Change decode_audio() interfaceGravatar uau2007-11-01
| | | | | | | | | | | | Rewrite decode_audio to better deal with filters that handle input in large blocks. It now always places output in sh_audio->a_out_buffer (which was always given as a parameter before) and reallocates the buffer if needed. After the changes filters can return arbitrarily large blocks of data without some of it being lost. The new version also allows simplifying some code. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24920 b3059339-0415-0410-9bf9-f77b7e298cf2
* Remove some pointless 'inline' qualifiersGravatar uau2007-11-01

* libaf: Remove rational number implementationGravatar uau2007-11-01
| | | | | | | | Remove the mul/cancel/gcd functions and some related code. Use ff_gcd instead of the removed af_gcd in af_resample.c. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24917 b3059339-0415-0410-9bf9-f77b7e298cf2
* libaf: change filter input/output ratio calculationsGravatar uau2007-11-01
| | | | | | | | | | Change the audio filters to use a double instead of rationals for the ratio of output to input size. The rationals could overflow when calculating the overall ratio of a filter chain and gave no real advantage compared to doubles. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24916 b3059339-0415-0410-9bf9-f77b7e298cf2
