      ProcessSmil processes editing of one source group (which may contain multiple source tracks) to one set of outputs (to one or more encoding profiles). Note that the source tracks are expected to have the same dimensions.
      Specified by:
      processSmil in interface org.opencastproject.composer.api.ComposerService
      Parameters:
      smil - - smil containing with video names and clip sections from them
      trackparamId - - group id
      mediaType - - VIDEO_ONLY, AUDIO_ONLY, or "" if neither is true
      profileIds - - list of encoding profile Ids
      Returns:
      Compose Job
      Throws:
      org.opencastproject.composer.api.EncoderException - - if encoding fails
      org.opencastproject.mediapackage.MediaPackageException - - if missing files or bad mp

      Splice segments given by smil document for the given track to the new one. This function reads the smil file and reduce them to arguments to send to the encoder
      Parameters:
      job - processing job
      smil - smil document with media segments description
      trackParamGroupId - source track group
      mediaType - VIDEO_ONLY or AUDIO_ONLY or "" if it has both

      A single encoding process that produces multiple outputs from a single track(s) using a list of encoding profiles. Each output can be tagged by the profile name. This supports adaptive bitrate outputs.
      Parameters:
      job - - encoding job
      track - - source track
      profileIds - - list of encoding profile Ids, can include one adaptive profile
      Returns:
      encoded files
      Throws:
      org.opencastproject.composer.api.EncoderException - - if can't encode
      IllegalArgumentException - - if missing arguments
