tests/swscale: use yuva444p as reference Instead of the lossy yuva420p. This does change the results compared to the status quo, but is more reflective of the actual strength of a conversion, since it will faithfully measure the round-trip error from subsampling and upsampling. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=1707e81073cebd419333b8e115a02d1a9d9588c2 --- libswscale/tests/swscale.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/libswscale/tests/swscale.c b/libswscale/tests/swscale.c index a30be077ab..04c07e19c4 100644 --- a/libswscale/tests/swscale.c +++ b/libswscale/tests/swscale.c @@ -82,7 +82,7 @@ static int fmt_comps(enum AVPixelFormat fmt) static void get_mse(int mse[4], const AVFrame *a, const AVFrame *b, int comps) { - av_assert1(a->format == AV_PIX_FMT_YUVA420P); + av_assert1(a->format == AV_PIX_FMT_YUVA444P); av_assert1(b->format == a->format); av_assert1(b->width == a->width && b->height == a->height); @@ -90,8 +90,8 @@ static void get_mse(int mse[4], const AVFrame *a, const AVFrame *b, int comps) const int is_chroma = p == 1 || p == 2; const int stride_a = a->linesize[p]; const int stride_b = b->linesize[p]; - const int w = (a->width + is_chroma) >> is_chroma; - const int h = (a->height + is_chroma) >> is_chroma; + const int w = a->width; + const int h = a->height; uint64_t sum = 0; if (comps & (1 << p)) { @@ -499,7 +499,7 @@ bad_option: goto error; ref->width = opts.w; ref->height = opts.h; - ref->format = AV_PIX_FMT_YUVA420P; + ref->format = AV_PIX_FMT_YUVA444P; if (sws_scale_frame(sws[0], ref, rgb) < 0) goto error; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
