Concat Operation is not compatible with ffmpeg 4.x anymore

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Critical
    • Resolution: Fixed and reviewed
    • Affects versions: 5.0
    • Fix versions: 5.2
    • Components: Backend Software
    • Labels:
      None
    • Severity:
      Incorrectly Functioning Without Workaround
    • Steps to reproduce:
      Hide
      Steps to reproduce:
      1. Make sure you use Opencast with ffmpeg 4.0+
      2. Use a workflow that adds a trailer (use animate operation i.e.) or something similar
      3. The workflow fails in the concat operation.
      4. ffmpeg throws the error " This syntax is deprecated. Use '|' to separate the list items ('0:d=1' instead of '0::d=1')"
      5. This is caused by the ffmpeg filter "aevalsrc=0::d=1[silent1]". The two :: are hard coded in Opencast's composer-ffmpeg.
      6. In older ffmpeg versions channels were sepearated by ":" in this filter. Now they are sepearated by "|". But we only have one channel (I hope that is still right) and so we probably do not need the separator at all and one ":" should be enough.
       
       Actual Results:
       
       
       Expected Results:
       
       
       Workaround (if any):
