From d01e684186bc1631bc176f06b89d33c27ec0d24d Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Thu, 16 Jan 2014 15:59:05 -0500 Subject: [PATCH] mov: do not set avg_frame_rate in the demuxer The track duration is often not reliable or is not the duration represented by the number of frames. In those cases, avg_frame_rate was reported incorrectly. Removing this code falls back to the default calculation in avformat_find_stream_info(). This is a partial revert of commit c3aeaa540.
