◆ streamAttributes()
|
inlinevirtual |
Configures a PiPo module according to the input stream attributes and propagate output stream attributes.
PiPo module: Any implementation of this method requires a propagateStreamAttributes() method call and returns its return value, typically like this:
return this->propagateStreamAttributes(hasTimeTags, rate, offset, width, height, labels, hasVarSize, domain, maxFrames);
PiPo host: A terminating receiver module provided by a PiPo host handles the final output stream attributes and usally returns 0.
- Parameters
-
hasTimeTags a boolean representing whether the elements of the stream are time-tagged rate the frame rate (highest average rate for time-tagged streams, sample rate for audio input) offset the lag of the output stream relative to the input width the frame width (number of channels for audio or data matrix columns) height the frame height (or number of matrix rows, always 1 for audio) labels optional labels for the frames' channels or columns (can be NULL) hasVarSize a boolean representing whether the frames have a variable height (respecting the given frame height as maximum) domain extent of a frame in the given domain (e.g. duration or frequency range) maxFrames maximum number of frames in a block exchanged between two modules (window size for audio)
- Returns
- 0 for ok or a negative error code (to be specified), -1 for an unspecified error
