it looks like it's streaming but chrome just isn't playing. If anyone knows how to resolve this (or an alternative transcoder line that would get this done) then that would be greatly appreciated.

Interesting. http://caniuse.com/#search=ogg suggests you shouldn't even have Safari working, as far as the native audio tag goes.

If this is Chrome on a desktop, maybe view the developer's console and see if there is any output there?

yeah, that's my bad. I subsequently realised that safari was defaulting to mp3 as opposed to ogg, so it's actually not working at all

if anyone could advise re: setting up ffmpeg to allow for in-browser ogg streaming that would be greatly appreciated.

My first attempts didn't work.

I guess what is important are also the to/from fields for the transcoder, as well as the ffmpeg line, to be sure it is attempting the right conversion at all.
