It is unsigned at least on arm, fixes the following warnings: libavfilter/vf_signalstats.c:833:21: warning: taking the absolute value of unsigned type 'unsigned int' has no effect dify += abs(yuv - AV_RN16(prev->data[0] + pw + i * 2)); --- libavfilter/vf_signalstats.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'libavfilter/vf_signalstats.c') diff --git a/libavfilter/vf_signalstats.c b/libavfilter/vf_signalstats.c index 298881bc72..2b8c0de4c4 100644 --- a/libavfilter/vf_signalstats.c +++ b/libavfilter/vf_signalstats.c @@ -830,7 +830,7 @@ static int filter_frame16(AVFilterLink *link, AVFrame *in) masky |= yuv; histy[yuv]++; - dify += abs(yuv - AV_RN16(prev->data[0] + pw + i * 2)); + dify += abs(yuv - (int)AV_RN16(prev->data[0] + pw + i * 2)); } w += in->linesize[0]; pw += prev->linesize[0]; @@ -848,9 +848,9 @@ static int filter_frame16(AVFilterLink *link, AVFrame *in) masku |= yuvu; maskv |= yuvv; histu[yuvu]++; - difu += abs(yuvu - AV_RN16(prev->data[1] + cpw + i * 2)); + difu += abs(yuvu - (int)AV_RN16(prev->data[1] + cpw + i * 2)); histv[yuvv]++; - difv += abs(yuvv - AV_RN16(prev->data[2] + cpw + i * 2)); + difv += abs(yuvv - (int)AV_RN16(prev->data[2] + cpw + i * 2)); histsat[p_sat[i]]++; histhue[((int16_t*)p_hue)[i]]++; -- cgit v1.2.3
