Subject: [FFmpeg-devel] [PATCH 6/6] avcodec/mpv_reconstruct_mb_template: Optimize dead code away
Date: Mon, 17 Oct 2022 03:34:42 +0200
Message-ID: <GV1P250MB0737BB636B363E909D3782128F299@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM> (raw)
In-Reply-To: <GV1P250MB0737DB7E1DA91101E51ECD208F299@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM>
None of the MPEG-1/2 codecs support frame threading,
so one can optimize the check for it away.
