Description Thibault Saunier 2015-09-11 16:04:08 UTC
Running a simple scenario like:

  description, seek=true, duration=20, need-clock-sync=true, handles-states=true
  seek, start=1.0, flags=accurate+flush


  GST_VALIDATE_SCENARIO=scenario ges-launch-1.0 +clip $HOME/gst-validate/gst-integration-testsuites/medias/defaults/matroska/numerated_frames_blue.mkv

leads to a black frame because the first buffer in videoaggregator has a running time of 1, and it expects something between 0 and 1.
