As requested in SuperUltraCriticalShowstopper request #2685
I have built an analyzer based on Rainbow Dash
...oh god, what have I done...
This will either make some people happy, or is absolute garbage.
Block analyzer uses an internal variable m_step to determine how
long to hold a bar up. This is dependant on framerate, however it is
only set on creation or resize of the analyzer. This patch changes
this value whenever the framerate is changed, preventing the analyzer
from appearing wildly fast or extremely slow until a restart.
The analyzers are sent new buffers of audio data to process each time
they pass through the gst pipeline. Different file formats and bit depths/
sample rates can change the size of these buffers, in some cases making them
large and therefore infrequent. This causes choppiness in the analyzer
as it is not getting new data with every frame. This patch chunks the buffers
coming off the pipeline to correspond with the framerate of the analyzer.
This patch prevents the framerate of all analyzers from
increasing beyond the framerate set in the interface at all times.
It however will allow the analyser to redraw as often as required
to prevent artifacting when the play scrubber is drawn in front.
