From 8f1580c31a3cfb9994bda7b3914a97e09b9f1d48 Mon Sep 17 00:00:00 2001 From: Derek Buitenhuis Date: Mon, 15 Mar 2021 14:20:17 +0000 Subject: [PATCH] avformat/mov: Handle when we have an mfra box but have not read the full sidx for a fragment Use the tfra timestamp if it is available and sidx timestamp is not. Fixes reading the entire file after seeking in a live-style DASH FMP4 with an MFRA. This specifically fixes when use_mfra_for is set.
