Subject: [FFmpeg-devel] [PATCH] Check codec whitelist in av_find_best_stream
Date: Thu, 27 Jan 2022 02:12:28 +0000
Message-ID: <CY4PR0501MB37305E8D8E7C943D397FBFB1AA219@CY4PR0501MB3730.namprd05.prod.outlook.com> (raw)
Modified the function av_find_best_stream() such that, when a list of
allowed codecs is supplied in the format context, and when the caller is
requesting a decoder be returned, the function will select the best
stream that has a decoder in the allowed decoders list.
