      avfilter/avf_showcqt: rewrite showcqt and add features · f8d429e0
      由 Muhammad Faiz 提交于 
      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

      avfilter/delogo: Set default band to 1 · 8bc708fc
      由 Jean Delvare 提交于 
      The original interpolation algorithm behaved poorly on the borders and
did not even guarantee continuity at the borders. For this reason, a
second interpolation/blending pass was required on the borders to make
them seamless.

However, since the interpolation algorithm was improved in June 2013,
the border issues no longer exist. The new algorithm does guarantee
continuity at the borders, making the second pass useless. A larger
band always increases the cumulated interpolation error. In most cases
it also increases the average interpolation error, even though the
samples in the band are only partially interpolated.

For this reason I would like to get rid of the "band" parameter. As a
first step, let's change its default value from 4 to 1 and document it
as deprecated.

I have benchmarked this change on a combination of input sources and
realistic logo areas. Lowering the band value from 4 to 1 resulted in
8 to 39 % less interpolation error per frame (or 1 to 34 % less
interpolation error per luma sample.)
