The silence operation performs a silence detection on an audio-only input file. The operation needs the silence detection API and impl (or remote in a distributed system) modules to be installed to process the request.

Parameter Table

configuration keys example description default value
source-flavors "*/audio" The input parameter source-flavors takes one flavor/sub-type or multiple input flavors with the *-operator followed by the sub-type EMPTY
reference-tracks-flavour "*/preview" The input parameter reference-tracks-flavour is the subtype of the media files that should be included in the provided SMIL file. The * should not be modified here. In most cases it is not important which reference-tracks-flavour is selected as long as all relevant flavors are available within this feature. "preview" is not a bad choice as all files available within the video editor UI are also available with this flavor, unlike "source" where not all flavors may be available, as some recorders record all streams to one file and the tracks are separated afterwards. The editor operation afterwards will anyway try to select the best available quality. EMPTY
smil-flavor-subtype "smil" The output parameter is smil-flavor-subtype which provides the modificatory for the flavor subtype after this operation. The main flavor will be consistent and only the subtype will be replaced. EMPTY
