Subject: [FFmpeg-devel] [PATCH 2/2] doc/examples/transcode_aac: Set decoder packet timebase
Date: Wed, 23 Feb 2022 15:58:28 +0100
Message-ID: <ef2f977e-64a9-5fc9-ce21-9748cac69ab2@gmail.com> (raw)
Previously, the default timebase caused two warnings during decoding about not being able to update timestamps for skipped and discarded samples, respectively.
