Paul B Mahol	4020787b5b	avfilter/avf_showspectrum: make colors for log scale more user friendly Previosly output was almost useless because background noise, due to windowing function picked and which is not actually present in audio, had too much brightness.

Ganesh Ajjanagadde	ec66bcc0e7	avfilter/avf_showspectrum: use log10 instead of log()/... This is likely more precise and conveys the intent better. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	6aaac24d72	avfilter/all: propagate errors of functions from avfilter/formats 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.
