Subject: [FFmpeg-devel] [PATCH 2/6] lavc/videotoolboxdec: fix escaping sequential zero sequences
Date: Mon, 09 May 2022 18:16:20 +0000
Message-ID: <20892390d0a34a97fd61a05bb4797ac648fd586c.1652120184.git.ffmpegagent@gmail.com> (raw)
In-Reply-To: <pull.23.ffstaging.FFmpeg.1652120184.ffmpegagent@gmail.com>
From: rcombs <rcombs@rcombs.me>
This ensure that e.g. 0000000000 becomes 00000300 000300,
rather than 00000300 0000.
