Subject: [FFmpeg-devel] [PATCH] checkasm: Increase the tolerance for ac3_sum_square_butterfly_float
Date: Wed, 24 Jul 2024 00:01:32 +0300
Message-ID: <20240723210132.95804-1-martin@martin.st> (raw)

Increase the tolerance from 10 ulp to 11 ulp. This fixes occasional
errors for some inputs; the errors could be reproduced on
aarch64/neon builds, with "checkasm --test=ac3dsp 3446175925".
