Ah. I was going to point out that the issue was that this was in no way an AVI.
Looks as if you figured that out by the time I woke up. I will give the update
a try. With the header working correct I suspect things will fall into place.

I figured out an ffmpeg visualization output last year. This is what I came up
with. It's basic but you kind of get the idea. Not sure how stable it will be.
I haven't tested it beyond maybe an hour or less.
```
#Super Fancy Streaming Visualizations
output.external(%wav,"ffmpeg -loglevel quiet -i pipe:0 -f webm -content_type
