Subject: [FFmpeg-devel] [PATCH v2 1/4] avformat/mov_chan: check channel count of layout tags at compile time
Date: Wed, 3 Apr 2024 00:40:48 +0200
Message-ID: <20240402224048.32011-1-cus@passwd.hu> (raw)
In-Reply-To: <GV1P250MB07373070C66D7FDF7F7EE8348F3F2@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM>
We can do this by using an X-macro for channel map declaration and doing a
static_assert() in one pass for the check. Thanks for Andreas Rheinhardt for
the suggestion.
