Subject: [FFmpeg-devel] [PATCH v3 2/6] {configure, avformat/movenc}: enable AC-3 parser for movenc
Date: Tue, 21 Jun 2022 09:46:30 +0300
Message-ID: <20220621064634.16797-3-jeebjp@gmail.com> (raw)
In-Reply-To: <20220621064634.16797-1-jeebjp@gmail.com>

From: Jan Ekström <jan.ekstrom@24i.com>

This simplifies the code to no longer have #ifs in a manner which
does not require handling avpriv_ac3_parse_header returning ENOSYS.

As an existing example, the MPEG-TS muxer already requires the AC-3
parser, and in order to fix existing issues with the current AC-3
movenc code, switching to use the AC-3 parser is required, so this
is an enabling change for that.
