Subject: [FFmpeg-devel] [PATCH v7 10/14] avcodec: add helper for configuring AVCodecContext's frame side data
Date: Thu, 29 Feb 2024 18:42:57 +0200
Message-ID: <20240229164307.3535613-11-jeebjp@gmail.com> (raw)
In-Reply-To: <20240229164307.3535613-1-jeebjp@gmail.com>

This allows API clients that wish to configure multiple entries
at a time to do so without writing the looping code themselves.
