* avfilter: Constify all AVFiltersAndreas Rheinhardt2021-04-27
| | | | | | | This is possible now that the next-API is gone. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avfilter/asrc_sine: Fix invalid left shift of negative numberAndreas Rheinhardt2021-03-28
| | | | | | | | | | by using a multiplication instead. The multiplication can never overflow an int because the sin-factor is only an int16_t. Affected the FATE-tests filter-concat and filter-concat-vfr. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* 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>

* lavfi: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.

* avfilter: avoid zero arguments to variadic macroGanesh Ajjanagadde2015-10-24
| | | | | | | | | ISO C requires at least one argument in the place of the ellipsis in a variadic macro. In particular, under -pedantic, this triggers the warning -Wgnu-zero-variadic-macro-arguments on clang 3.7.
