* avfilter/avf_showcqt: Replace all fmin* and fmax* by FFMIN/FFMAXMichael Niedermayer2015-10-31

* avfilter/avf_showcqt: rewrite showcqt and add featuresMuhammad Faiz2015-10-28
| | | | | | | | | | | | | | | | | | | | | add yuv444p, yuv422p, and yuv420p output format (lower cpu usage on ffplay playback because it does not do format conversion) custom size with size/s option (fullhd option is deprecated) custom layout with bar_h, axis_h, and sono_h option support rational frame rate (within fps/r/rate option) relaxed frame rate restriction (support fractional sample step) support all input sample rates separate sonogram and bargraph volume (with volume/sono_v and volume2/bar_v) timeclamp option alias (timeclamp/tc) fcount option gamma option alias (gamma/sono_g and gamma2/bar_g) support custom frequency range (basefreq and endfreq) support drawing axis using external image file (axisfile option) alias for disabling drawing to axis (text/axis) possibility to optimize it using arch specific asm code Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avfilter,swresample,swscale: use fabs, fabsf instead of FFABSGanesh Ajjanagadde2015-10-22
| | | | | | | | | | | | | | | | | | | | | | | | It is well known that fabs and fabsf are at least as fast and sometimes faster than the FFABS macro, at least on the gcc+glibc combination. For instance, see the reference: http://patchwork.sourceware.org/patch/6735/. This was a patch to glibc in order to remove their usages of a macro. The reason essentially boils down to fabs using the __builtin_fabs of the compiler, while FFABS needs to infer to not use a branch and to simply change the sign bit. Usually the inference works, but sometimes it does not. This may be easily checked by looking at the asm. This also has the added benefit of reducing macro usage, which has problems with side-effects. Note that avcodec is not handled here, as it is huge and most things there are integer arithmetic anyway. Tested with FATE.

* avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.

* avfilter: new multimedia filter avf_showcqt.cMuhammad Faiz2014-06-05
this filter is the same as showspectrum but with constant Q transform, so frequency is spaced logarithmically
