Clément Bœsch	0e62b5d1ef	avfilter: use AV_OPT_TYPE_BOOL in a bunch of places	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.

Clément Bœsch	304fdfe9f3	lavfi: add showwavespic filter This is a variant of showwaves. It is implemented as a different filter so that the user is not allowed to use meaningless options which belong to showwaves (such as rate). Major edits done by Stefano Sabatini, from a patch by ubitux.
