commit 62274859104bd828373ae406aa9309e610449ac5
Author: Ted Meyer <tmathmeyer@chromium.org>
Date:   Fri Mar 22 19:56:55 2024 +0000

Replace deprecated use of AVCodecContext::reordered_opaque
    
    We can use the AV_CODEC_FLAG_COPY_OPAQUE flag on the codec context
    now to trigger timestamp propagation.
