Actually, ffmpeg has to be installed on the MythWeb host, not the 
backend host, and the MythWeb host must have local-filesystem access to 
all the recordings you want to be able to stream (which could mean NFS 
or CIFS--but no backend streaming) and the MythWeb host has to be 
powerful enough to be able to transcode from whatever format you 
recorded to Flash on-the-fly in real time with the CPU (no VDPAU or 
other GPU assist).  (In these days of high-definition TV and, especially 
H.264, the last requirement is becoming a real pain.)

What's there, now, is a proof of concept to see whether it was worth 
adding the required code to the backend to allow Trash, er, I mean Flash 
streaming.  None who have used it have gotten motivated enough to do it 
right and add the required backend support for transcoding to 
Flash--either on-the-fly (for users with overpowered backends) or to 
store a 2nd pre-transcoded copy of the recording as Flash (for users who 
like to waste electricity transcoding everything they might want to 
stream some hours after the show is recorded), so if anyone really wants 
it, feel free to ask for some pointers on how the patches should work.  :)
