* avfilter/avf_showvolume: fix several issuesPaul B Mahol2015-11-29
| | | | | | | | | Fix color fading: previously color could fade to red when volume level for red color was actually never reached. Display volume value on right side. Use red color only if clipping is needed. Signed-off-by: Paul B Mahol <onemda@gmail.com>
* avfilter/avf_showvolume: use log10 instead of log()/M_LN10Ganesh Ajjanagadde2015-10-29
| | | | | | | This is likely more precise and conveys the intent better. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* 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.
