avfilter/vf_v360: add guards against NaNs Also normalize vector after rotation, it might be needed, otherwise one can get NaNs. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=0c9e01011b549f088d5afd06a82bcbffc589bcf9 --- libavfilter/vf_v360.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/libavfilter/vf_v360.c b/libavfilter/vf_v360.c index 4d59316bf6..01f0562728 100644 --- a/libavfilter/vf_v360.c +++ b/libavfilter/vf_v360.c @@ -33,6 +33,8 @@ * 5) Remap input frame to output frame using precalculated data */ +#include <math.h> + #include "libavutil/avassert.h" #include "libavutil/imgutils.h" #include "libavutil/pixdesc.h" @@ -2319,12 +2321,16 @@ static int config_output(AVFilterLink *outlink) out_transform(s, j, i, height, width, vec); else out_transform(s, i, j, width, height, vec); + av_assert1(!isnan(vec[0]) && !isnan(vec[1]) && !isnan(vec[2])); rotate(rot_mat, vec); + av_assert1(!isnan(vec[0]) && !isnan(vec[1]) && !isnan(vec[2])); + normalize_vector(vec); mirror(output_mirror_modifier, vec); if (s->in_transpose) in_transform(s, vec, in_height, in_width, r_tmp.v, r_tmp.u, &du, &dv); else in_transform(s, vec, in_width, in_height, r_tmp.u, r_tmp.v, &du, &dv); + av_assert1(!isnan(du) && !isnan(dv)); calculate_kernel(du, dv, &r_tmp, u, v, ker); } } _______________________________________________ ffmpeg-cvslog mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
