hi,
I'm writing an application that involves starting and stopping various filters on the same multiplex. Obviously, I want this to be as reliable as possible with the wide range of DVB cards now supported.
My question to the driver developers (especially for the less mature drivers) is should I set all required filters once when first tuning to the multiplex, and then discard packets from /dev/dvb/adapterN/dvrN that I don't need. Or is it 100% reliable to turn filters on and off from userspace?
i.e. if I am recording data from PID 1 and then want to add PID 2 for a short time, will PID 1 come through uninterrupted?
I can only speak for the skystar2 driver, but IMHO it should be perfectly safe to turn filters on and off from userspace (in fact, that's what scan does).
