 Summary of the bug:
 use segment, the first output file is abnormal. out000.flv can not show
 video by ffplay, but I can hear sound, from the log looks like the video
 data is corrupted. Rest output files such as out001.flv, out002.flv is
 able to play normally.

 How to reproduce:
 {{{
 ffmpeg -i input.mkv -c copy -f segment out%03d.flv
 ffplay out000.flv
 ffmpeg 4.2.2
 built on Linux, MacOS
 }}}
