PsyWave: difficulty to map to PsyStimulus

[maartenuni]

The inheritance forPsy Wave is

GObject -> PsyStimulus -> PsyAuditoryStimulus -> PsyGstStimulus -> PsyWave

Every stimulus in psylib is a PsyStimulus. PsyStimulus has the following API

psy_stimulus_play(PsyStimulus*, Psytimepoint) // You'll have to set the duration manually.
psy_stimulus_play_for(PsyStimulus*, PsyTimePoint*, PsyDuration) // All parameters from the perspective from the stimulus are set it should be ready to rumble
psy_stimulus_play_until(PsyStimulus*, PsyTimePoint*, PsyTimePoint*) Same as before, but duration is calculated.

However, to use a PsyGstStimulus, you'll have to set it to running. And setting it to running, requires the duration of the stimulus to be known, otherwise, the audiotestsrc can't be given an a specified number of buffers. Preferably the stimulus is set to running, because that starts the Gstreamer pipeline, otherwise the audio mixer might be unable to fetch GstSample* 's as the pipeline is stale.
