* Change to a 64 bit accumulation variable instead of shifting.reimar2007-11-181-5/+5
| | | | | | | | 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
* 100l, *ppc++ was supposed to be replaced by ppc[i] in r25100, but that is ↵reimar2007-11-181-2/+0
| | | | | | | | | | 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 accountuau2007-11-011-0/+5
| | | | | | | | | | | | | | | | | | 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 cleanupuau2007-11-011-10/+17
| | | | | | | | | 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 parsinguau2007-11-011-1/+1
| | | | | | | | | | 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 positionuau2007-11-011-2/+2
| | | | | | | | | 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
