Subject: [FFmpeg-devel] [PATCH 1/5] avformat/demux: Copy AVCodecContext properties in codec_close()
Date: Fri,  5 Jul 2024 00:25:51 -0500
Message-ID: <20240705052555.402920-2-marth64@proxyid.net> (raw)
In-Reply-To: <20240705052555.402920-1-marth64@proxyid.net>

After avformat_find_stream_info() calls codec_close(), the
properties are not copied in the newly created skeleton context
returned by codec_close(). This breaks display of the properties
when viewing stream information afterward e.g. via av_dump_format().

Copy the old properties over, thus fixing printing of the properties
(such as Closed Captions) in av_dump_format() that broke sometime
after 4.4.2.
