* avfilter/formats: Schedule avfilter_make_format64_list() for removalAndreas Rheinhardt2020-08-12
| | | | | | | | | | | | Despite its name, this function is not part of the public API, as formats.h, the header containing its declaration, is a private header. The formats API was once public API, but that changed long ago (b74a1da49db5ebed51aceae6cacc2329288a92c1, the commit scheduling it to become private, is from 2012). That avfilter_make_format64_list() was forgotten is probably a result of the confusion resulting from the libav-ffmpeg split. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avfilter/asrc_anoisesrc: change color variable to intLimin Wang2019-10-29
| | | | | | | | | | | | Or it'll cause invalid color and s->filter is NULL. Please reproduce it with below command on big endian system: $ ./ffmpeg -f lavfi -i "anoisesrc=d=60:c=1:r=48000" -f s16le -c:a pcm_s16le -f null - Segmentation fault (core dumped) Signed-off-by: Limin Wang <lance.lmwang@gmail.com> Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avfilter: Add blue and violet noise generation filtersGeorge Boyle2017-07-19
| | | | | | | | | For the blue and violet noise, I took the pink and brown noise respectively and subtracted the offsets instead of adding them. When I eyeball the frequency spectrum of the resulting outputs it looks correct to me, i.e. the blue graph appears to be a mirror image of the pink, and the same can be said of the violet and the brown. I did not do anything else to confirm the correctness.
