All incoming streams are decoded by default. This behaviour is specified by option


This option may be switched off in file if necessary (for example, to reduce the server load):


In this case, incoming streams will be decoded on request only:

  1. If transcoding is necessary
  2. If decoding is necessary when taking a PNG snapshot of the stream

In the cases above, decoder is created only for the time of transcoding or snapshot taking, and is stopped after the operation is completed.
