2016-01-27avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis
Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
2015-12-21lavfi/vf_histogram: replace round by lrintGanesh Ajjanagadde
lrint is at least as fast, uses a superior rounding mode, and avoids an implicit cast. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
2015-12-01avfilter/vf_histogram: remove deprecated stuffPaul B Mahol
Remove all modes except levels mode. Users should already switch to other filters with extended funcionality: vectorscope and waveform. Signed-off-by: Paul B Mahol <onemda@gmail.com>
2015-10-14avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde
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.
