Subject: [FFmpeg-devel] [PATCH 2/3] avcodec/mlpdec: Use get_bits() instead of get_bits_long() when possible
Date: Wed, 5 Jan 2022 22:38:34 +0100
Message-ID: <AM7PR03MB6660F9B8662C7DBB75B266658F4B9@AM7PR03MB6660.eurprd03.prod.outlook.com> (raw)
In-Reply-To: <AM7PR03MB6660AEBDE14E5E4DB94238838F4B9@AM7PR03MB6660.eurprd03.prod.outlook.com>
huff_lsbs is guaranteed to be in the range of 0..24 and
so is lsb_bits here, so one can use get_bits().
