Hi, I have a patch for bug #8027 <https://trac.ffmpeg.org/ticket/8027> (see attachment).
But there is still a problem with -0.0, but FFABS(-0.0) works fine. Testcode: av_log(NULL, AV_LOG_ERROR, "FFSIGN(0): %d\n", FFSIGN(0)); av_log(NULL, AV_LOG_ERROR, "FFSIGN(-0): %d\n", FFSIGN(-0)); av_log(NULL, AV_LOG_ERROR, "FFSIGN(0.0D): %d\n", FFSIGN(0.0D)); av_log(NULL, AV_LOG_ERROR, "FFSIGN(-0.0D): %d\n", FFSIGN(-0.0D)); av_log(NULL, AV_LOG_ERROR, "FFSIGN(-0.0F): %d\n", FFSIGN(-0.0F)); av_log(NULL, AV_LOG_ERROR, "FFSIGN(-0.0): %d\n", FFSIGN(-0.0)); av_log(NULL, AV_LOG_ERROR, "FFABS(0): %d\n", FFABS(0)); av_log(NULL, AV_LOG_ERROR, "FFABS(-0): %d\n", FFABS(-0)); av_log(NULL, AV_LOG_ERROR, "FFABS(0.0D): %f\n", FFABS(0.0D)); av_log(NULL, AV_LOG_ERROR, "FFABS(-0.0D): %f\n", FFABS(-0.0D)); av_log(NULL, AV_LOG_ERROR, "FFABS(-0.0F): %f\n", FFABS(-0.0F)); av_log(NULL, AV_LOG_ERROR, "FFABS(-0.0): %f\n", FFABS(-0.0)); Results: FFSIGN(0): 1 FFSIGN(-0): 1 FFSIGN(0.0D): 1 FFSIGN(-0.0D): 1 FFSIGN(-0.0F): 1 FFSIGN(-0.0): 1 FFABS(0): 0 FFABS(-0): 0 FFABS(0.0D): 0.000000 FFABS(-0.0D): -0.000000 FFABS(-0.0F): -0.000000 FFABS(-0.0): -0.000000 -Ulf _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
