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.

Nicolas George	d4de6d4fad	lavfi/avf_showspectrum: do not push the frame at EOF. It is always identical to the last pushed frame. The samples in the last incomplete window were ignored, this is unchanged. Possible enhancement: pad the last incomplete window with silence.	10 years ago

Clément Bœsch	ee0a8bcba1	lavfi/showspectrum: fix outpicref initialization. In 81f2549, output pixel format was changed from rgb24 to planar yuv, but the initialization was left unchanged. As a result, the chroma planes were left uninitalized. This was not noticed since the current ff_get_video_buffer() seems to be initializing the buffer. This won't be the case anymore after the Evil Plan.	12 years ago

Rudolf Polzer	773fc6e0c7	lavfi/showspectrum: set default height to 512 Only power-of-two FFTs are supported; so to get a full spectrum (that is, one up to Nyquist), the height must be a power of two.
