Antti, Just to be sure -- which device driver did you use for your testing, and are you using the exact code in Mauro's for_v3.2 branch, or modified code?

OK... I think it's safe to remove that code. The only time that "adap->active_fe" should really be set to -1 is at startup, before *any* frontend is used.

Does removal of those two lines fix it for > you completely? BTW, I understand the cause of this now -- this error case occurs when the application stops streaming but leaves the frontend open. (for instance, to change the channel) We only want to set (adap->active_fe = -1) if ( ((adap->feedcount == onoff)&& (!onoff)) AND ALSO only if the file handle gets closed. It's safe to just disable those lines for now. Regards, Mike Krufky ^ permalink raw reply [flat|nested] 7+ messages in thread
