Without the file cannot really check, but "stream seems to contain no keyframes" would indicated that the file was muxed incorrectly, in a way that does not allow seeking.

comment:2 Changed 2 years ago by beastd

  • Keywords HEVC h265 seekbar removed
  • Priority changed from highest to normal
  • Resolution set to needs_more_info
  • Status changed from new to closed

Can you still reproduce the problem?

Does it only happens on that particular file?
