Subject: [FFmpeg-devel] [PATCH 2/9] lavf/demux: restrict video parser duration handling to just GIF
Date: Sun, 1 Oct 2023 14:55:45 +0200
Message-ID: <20231001125552.23976-2-anton@khirnov.net> (raw)
In-Reply-To: <20231001125552.23976-1-anton@khirnov.net>
The parser does not have a timebase associated with it, so in general it
makes no sense for it to be exporting durations. Longer-term this
should be handled more cleanly with a new parser API.
