Commerical flagging is possible both with both previous and current CVS although with 2-3 different methods. Previous releases allowed you to setup a dedicated mythbackend that didn't have any tuners and then go into config and setup that backend as a dedicated commercial flagging host. Current CVS has a JobQueue and commercial flagging and transcoding jobs are fired off via the JobQueue. You can use the same method above to setup a dedicated backend but the concept of a "dedicated commercial flagging host" is gone. There is a screen in the backend setup program that lets you specify which jobs are allowed to run on that backend, so you could setup myth to only run commercial flagging on 2 out of 3 of your backends, or 1 out of 3, etc.. There is also a new mythjobqueue executable in CVS that lets you just run mythjobqueue without setting up a full (tunerless) backend on a machine. You just run the backend setup to setup the allowed JobQueue jobs and fire off mythjobqueue and it will start processing jobs out of the queue. Commercial flagging will work on any machine, but I am not sure about transcoding. I believe the transcoder requires direct access to the recordings directory, so you might be able to get remote transcoding jobs working if you have a shared NFS recordings directory, but Geoffrey would be able to give a more definite answer on that than I can since he wrote the transcoder. I run mythjobqueue occasionally on one my development machine to process jobs in the queue since it can process them quicker than my slow master backend can do them. -- Chris
