The scaler module scales the frames of a stream. It receives a single input stream and passes it on with a different size.
The configuration of the scaler module with name NAME
is located in the scalers/NAME subdirectory.
The file instream contains the name of the stream to
receive.
The frames received from this stream are scaled and passed to the
output stream.
The file size describes the size of the output stream,
i.e. its dimensions.
The file must contain a string
<width>x<height>,
e.g. 18x8 for 18 pixels width, 8 pixels height.
The file outstream contains the name of the stream to
send the scaled frames to.
