Subject: [FFmpeg-devel] [PATCH] avcodec/adpcmenc: Round up required buffer size
Date: Thu, 15 Sep 2022 17:58:11 +0200
Message-ID: <GV1P250MB073732E5EBBBB202D53994B38F499@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM> (raw)
Otherwise the buffer might be too small. Fixes assert violations
when encoding mono audio with exactly one sample.
