Subject: [FFmpeg-devel] [PATCH 22/35] avcodec/proresenc_anatoliy: remove IS_NEGATIVE() macro
Date: Mon, 11 Dec 2023 02:35:23 +0100
Message-ID: <20231211014429.1841681-23-u@pkh.me> (raw)
In-Reply-To: <20231211014429.1841681-1-u@pkh.me>

This makes the function closer to encode_acs() in proresenc_kostya.
