From 9ae4863cc57c38fa2f41f3b8c732fede4a2b78c6 Mon Sep 17 00:00:00 2001 From: Wenbin Chen Date: Tue, 15 Aug 2023 16:34:25 +0800 Subject: [PATCH] libavfilter/vf_vpp_qsv: Fix a timestamp bug when framerate is not set If user doesn't set framerate when he creates a filter, the filter uses default framerate {0, 1}. This causes error when setting timebase to 1/framerate. Now change it to pass inlink->time_base to outlink when framerate is not set.
