Subject: [FFmpeg-devel] [PATCH 6/7] avcodec/mpegvideo: Remove always-false check
Date: Wed, 26 Oct 2022 04:01:47 +0200
Message-ID: <AS8P250MB0744F40DB410D3C26BBEF5688F309@AS8P250MB0744.EURP250.PROD.OUTLOOK.COM> (raw)
In-Reply-To: <AS8P250MB0744149DC87FAB32814CAF938F2E9@AS8P250MB0744.EURP250.PROD.OUTLOOK.COM>

This basically reverts cc0380222add8df8ff9b3bd95eaf2b9d8c4c0d11.
At the time of said commit, cleanup on init failure was very
buggy. For codecs with the INIT_CLEANUP cap, the close function
could be called on error even before the private data has been
allocated; and when using frame threading the same could also
happen even without said flag. Some mpegvideo decoders were
affected by the latter.

Yet both of these issues have been fixed long ago, the latter
in commit e9b66175793e5c2af19beefe8e143f6e4901b5df. Therefore
the workaround in ff_mpv_common_end() can be removed.
