Subject: [FFmpeg-devel] [PATCH 2/2] avcodec/mpeg4videodec: Keep data_partitioning in sync between threads
Date: Wed, 17 Aug 2022 15:29:18 +0200
Message-ID: <DB6PR0101MB2214DA4993D763D04B80BF008F6A9@DB6PR0101MB2214.eurprd01.prod.exchangelabs.com> (raw)
In-Reply-To: <DB6PR0101MB2214BCE4702315DE7987846C8F689@DB6PR0101MB2214.eurprd01.prod.exchangelabs.com>
Fixes frame-threaded decoding of samples created by concatting
a video with data partitioning and a video not using it.
(Only the MPEG-4 decoder sets this, so it is synced in
mpeg4_update_thread_context() despite being a MpegEncContext-field.)
