comment:1 Changed 5 years ago by mrskman

Sample uploaded to your FTP (ticket_4227_dnxhd_segfault.mov). Sorry for the size but I don't know how to make it smaller and still reproducible. I have tested it with v2.5.2 and it still segfaults.

comment:2 Changed 4 years ago by michael

  • Reproduced by developer set
  • Resolution set to fixed
  • Status changed from new to closed

comment:3 Changed 4 years ago by cehoyos

  • Component changed from undetermined to avcodec
  • Keywords crash SIGSEGV dnxhd added
  • Priority changed from normal to important
  • Version changed from unspecified to git-master

The cut sample in http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4227/ needed -threads 1 to crash.

Note: See TracTickets for help on using tickets.
