ultimately- audio analysis request will spawn a task - there will be another call that will check progress

audio analysis will be saved - to a file? into a db?

for now - dump analysis into the http request

Running plugin: "qm-segmenter"...
Using block size = 26460, step size = 8820
Plugin accepts 1 -> 1 channel(s)
Sound file has 2 (will mix/augment if necessary)
Output is: "segmentation"

load a movie and retreive frames
save a movie

how do we deal with frames in libavcodec - can we request a frame by number
how do we deal with resolution
